Approximately 25 documents describe the mine and its natural and cultural environments. The documents contain numerous color maps and illustrations. Access to approx. 130 drawings from a series of original blueprints will be available in the near future.\nAll the materials in this collection were made available to the citizens of Wisconsin at the Ladysmith Public Library during the life of the mine. They were donated to the Kurt F. Wendt Library, University of Wisconsin-Madison after the mine closed. Wendt Library holds the print copies.\nThis summary of the history of the mine and the permit process is based on the website \"Reclaimed Flambeau Mine\" by the Wisconsin Department of Natural.\nBeginning in 1974, Kennecott Minerals Company initiated the process to obtain a mining permit in accordance with the newly adopted Metallic Mining Reclamation Act. The project as proposed in the mid-1970s involved mining the ore body in two phases, an 11-year open pit phase followed by an 11-year underground mining operation.\nFlambeau Mining Company, a subsidiary of Kennecott Minerals Company, formally restarted the permitting process for the project in 1987, starting a three year process of baseline data gathering, negotiations with local communities, and project design and review.\nThe Wisconsin Department of Natural Resources issued the Final Environmental Impact Statement for the project in early 1990 and the permit hearing was held during the summer. The independent hearing examiner issued all necessary permits in January 1991 and construction of the project site began in July 1991.\nOre shipments from the site began in May 1993 and continued for just over 4 years. Backfilling of the pit took about 1.5 years and reclamation activities at the site were generally completed by the end of 1999.\nThe 181-acre mining site located about one mile south of Ladysmith, Wisconsin, is bounded on the east by State Highway 27 and on the west by the Flambeau River.\nThe Flambeau deposit existed at very shallow depth. Depth to bedrock at the mining site ranged from about 15-40 feet. Glacial sand, gravel and till overlaid sporadically occurring Cambrian sandstone which in turn sat above the weathered pre-Cambrian metamorphic rocks containing the Flambeau deposit.\nMining of this shallow ore body was accomplished through a 32-acre open pit. The pit trended in a northeast-southwest direction and was 2,600 feet long, about 550 feet in width, and reached an ultimate depth of about 220 feet.\nOver the course of the mining operation, about 1.9 million tons of ore containing about 8.9% copper and 0.10 ounces of gold per ton were mined and shipped from the site. The mine produced about 178,000 tons of marketable copper and 328,000 ounces of gold.\nThe approved Reclamation Plan for the Flambeau Project specified that the open pit, upon completion of mining, would be completely backfilled with original rock material that was separated from the ore (waste rock and glacial overburden). Reclamation of the pit began in early 1997 and was completed in late 1998.\nFor additional documents not available via this digital collection, see the Bibliography of Historical Flambeau Mine Technical Reports, Environmental Monitoring Data, Correspondence, Diagrams, Legal Briefs and Photos (1969 - 2020+), Second Edition, published by Deer Tail Scientific.\nThis compilation (including design, introductory text, organization, and descriptive material) is copyrighted by University of Wisconsin System Board of Regents.\nThis copyright is independent of any copyright on specific items within the collection.

According to the African Review May 10, 1902 Prior to 1899 Eritrea had never been prospected for minerals and during that year it was brought to the attention of the Governor of the Colony Signor Martini that a large block of rich gold-bearing quartz had been discovered by a native. Shortly thereafter two experienced prospectors with the aid of natives came to the conclusion that many of the outcropping quartz reefs contained gold. The Eritrea gold mining company was established in June of 1900 and the mines of Sciumaghelle with a depth of 200 feet and Medrizien with a depth of 140 feet were selected for the initial operations. By December 31, 1901 the two mines had yielded about 6 ounces of gold. Other mines were also set up at Regina di Saba, Adiconsi and Az Nefas with similar results. According to the Annual Report of the Director of the Mint (Washington) for the Fiscal Year Ended June 30, 1903 page 237 \"In 1902 gold in the amount of 5,920 lire was coined, in pieces of 20 lire, using in part, as an experiment, metal obtained from the mines of Eritrea and in part gold purchased\". When divided by 20 the number comes to 296 total pieces struck for that year between domestic and imported gold. Also stated in the Mint report page 237: \"Gold Produced from mines of the country during 1902: Kilograms, 11. The value of the gold produced, 37,811 Lire\" and \"Gold product of the colonies of the country during 1902: The gold Mining Company of Eritrea in the year 1902 continued the preliminary work begun in 1901, with satisfactory results. However, we have no figures as to the quantity of the production.\" Clearly not all of the gold produced during this year was used in the manufacture of coinage and must have been either deposited in the treasury, exported or used for other manufacturing.

China currently dominates the production and processing of critical minerals like cobalt and lithium, which are crucial for the energy transition. This has raised concerns among Western governments about their dependence on Beijing. Despite the risks associated with operating in Africa, Western companies and investors are increasingly willing to build processing plants on the continent. These investments not only address the demand for local processing from African governments but also provide an alternative to China for Western auto manufacturers.\nOne example is Australian mining giant BHP Group, which has invested $100 million in a nickel mine in Tanzania and plans to build a processing plant in the country. This facility, expected to be the first of its kind in Africa, will produce battery-grade nickel for the US and global market by 2026. The trend of investing in processing facilities in Africa is likely to continue due to the growing demand for battery metals and China’s current dominance in the industry. London-based fund Vision Blue Resources has invested in a graphite mine in Madagascar and a processing facility in Mauritius, both of which are touted as the first of their kind outside of China. The company is also backing a cobalt refinery in Zambia, which is set to become the world’s third-largest and the largest outside of China. Western companies are willing to pay a premium for materials that meet environmental and labor standards, are traceable, and are produced outside of China. Despite the challenges, many Westerners believe the opportunities in Africa outweigh the risks, as they seek non-Chinese sources of battery metals.\nPressure on Western Miners to Process Metals in Africa as China Dominates Battery Supply Chain\nWestern miners are facing increasing pressure to establish supply chains for electric-vehicle (EV) batteries that bypass China, as Beijing dominates both the production and processing of critical minerals such as cobalt and lithium. This dependence on China has raised concerns among Western governments, prompting some companies and investors to build processing plants in Africa. By processing the raw materials they mine on the continent locally, these companies can export the refined materials directly to Europe and the U.S. This move also aligns with the demands of African governments for more local processing of metals and minerals extracted from their soil.\nAustralian mining giant BHP Group has invested $100 million in a nickel mine in Tanzania, along with U.S.-based Lifezone Metals. The companies plan to build a processing plant in Tanzania, which will be the first of its kind in Africa. The plant is expected to deliver battery-grade nickel to the global market, including the U.S., by 2026. London-based investment fund Vision Blue Resources has also invested in a new graphite mine in Madagascar and a processing facility in Mauritius. The company aims to establish the first graphite processing facility outside of China. Additionally, Vision Blue is backing a cobalt refinery in Zambia, which is expected to be the world’s third-largest and the largest outside of China once completed.\nAccording to Jacques Nel, head of Africa Macro at Oxford Economics Africa, investments in processing facilities in Africa are likely to increase due to the expected boom in demand for battery metals and China’s current dominance in the industry. Western companies are willing to pay a premium for materials that meet certain environmental and labor standards and are traceable, as long as they are produced outside of China. This presents an opportunity for African countries to become alternative suppliers to Western auto manufacturers and other green-tech manufacturers in Europe and the U.S.\nDespite the growing interest from investors, there are significant challenges for companies doing business in Africa. Some countries, such as the Democratic Republic of Congo, Guinea, Namibia, and Zimbabwe, have implemented resource nationalism policies, seeking a larger share of mining companies’ revenue. Zimbabwe, for example, banned the export of raw lithium, forcing foreign companies to process it within the country. Chinese competitors also have an advantage due to their established presence and appetite for risk in Africa.\nHowever, many Western companies believe that the opportunity in Africa outweighs the risks. Chris Moorman, Chief Commercial Officer at U.S.-based refiner ReElement Technologies, stated that doing business in Africa is not as daunting as some people believe. The company recently signed an offtake agreement to process lithium mined in South Africa and is building a processing facility in the country. They are in talks with four Western automotive manufacturers interested in purchasing African-sourced lithium. This shift in attitude reflects the growing demand for non-Chinese sources of battery metals.\nIn conclusion, the pressure to establish supply chains for EV batteries that bypass China is leading Western miners to build processing plants in Africa. By refining the raw materials they mine on the continent locally, these companies can export the refined metals directly to Europe and the U.S. Despite the challenges and risks associated with doing business in Africa, Western companies are increasingly willing to invest in the region. This trend is driven by the expected boom in demand for battery metals and the desire for alternative suppliers to China in the Western world.", "domain": "mining_engineering"}

It produced small amounts of silver from time to time for nearly 100 years. But today the mine is famous not for silver, but for fine rhodochrosite, a collector's gem found in just a few places in the world.\nRhodochrosite is a manganese carbonate by chemical composition, and it is the manganese that is responsible for the rose-like color. Rhodochrosite is most commonly light red or pink and is usually cut as cabochons or carved. Transparent red crystals are very rare, and the large red crystals found in the Sweet Home Mine are famous among mineral and gem collectors. Lower grade rhodochrosite from mines in Argentina displays alternate bands of color like agate.\nGemologically, rhodochrosite is a soft stone with a hardness of just 3.5 to 4 on the Mohs scale. It has a density of 3.45 to 3.70, about the same as topaz, and a refractive index of 1.597 to 1.816. The refractive index has a wide range due to variations in chemical composition.\n|Rhodochrosite Cabochons, Sweet Home Mine, Colorado|\nRhodochrosite was described in 1813 based on a sample from a silver mine in Romania. It tends to form in hydrothermal veins associated with silver, lead and copper sulfides. It can easily be confused with rhodonite, a manganese silicate, but rhodonite is a harder material, with a rating of 5.5 to 6.5.\nWhile rhodochrosite has been found in many places where silver is mined in North and South America, the red crystals from the Sweet Home Mine are so unusual that rhodochrosite was named the state mineral of Colorado in 2002.", "domain": "mining_engineering"}

Since acquiring the property in 2000, we have focused our analysis, design, planning, and permitting efforts on Golden Dream.\nAn internal feasibility study of Golden Dream conducted by our staff engineers indicates probable underground mineral reserves of 1.17M tons containing 258,000 oz. of gold and 8.5M lbs of copper. Following successful production start up at Golden Dream, we will expand our focus to other deposits in the immediate area with the objective of bringing additional deposits into additional production.\nIn November 2011, we posted the $591,474 Reclamation Bond and the Montana Department of Environmental Quality (“MDEQ”) approved the Golden Dream Operating Permit (#00173). Golden Dream is now fully permitted and bonded for mining operations between 500 and 1,000 tons a day.\nAs of April 2013, we have developed 650 feet of a 14’ X 14’ main underground access tunnel and 350 feet of a 12’ X 12’ underground ore access tunnel. In Q3 2012, we completed underground and surface water treatment and disposal infrastructure necessitated by our Operating Permit. The main underground access ramp will be used to transport mined ore to the surface. Ore will then be transported by road to the Mill Complex at Montana Tunnels for concentration; concentrated ores will be sold and shipped to a smelter.\nOur initial production plan targets the main pyrrhotite zone. Beginning in Q3 2013, we plan to extend the Golden Dream primary access ramp to reach deeper ore zones. A “bore” raise will be completed from surface into the main access ramp as a secondary egress. We expect to achieve initial ore production by Q4 2013 and full production by Q2 2014. Concurrent with development, the Mill Complex at Montana Tunnels will be re-commissioned to allow for processing ore shipments. We anticipate production of 55,000 oz. of gold in Year One.\nWe believe that Golden Dream mine life could be extended beyond ten years at anticipated peak production levels.

Success, thus far, had eluded them. Taking a circuitous route to the south to avoid being followed, they explored the rocky slopes of a nameless mountain. On April 25, 1895, Charles Burcham, F. M. Mooers, and John Singleton found what they had been looking for - gold and lots of it. Only forty seven years had passed since James Marshall inadvertently started California's gold rush with a chance find at Sutter's Mill.\nEight claims were first filed. The new mine was called the Yellow Aster, either for the name of a local flower, or for the title of a book one of the miners was reading. A new mining district was organized. It was called the Rand District after the Witwatersrand gold mining district in South Africa.\nThings were beginning to grow. On December 20, 1895, thirty three residents officially organized Rand Camp. The name was soon changed to Randsburg. In 1896, 1500 people were living in the area. The same year marked the start of serious milling (refining) operations for the Yellow Aster. Water was scarce, so the ore was hauled down the hill to Garlock where there was both water and milling facilities\nIn 1898, a railroad spur line that connected with the Santa Fe's Los Angeles to Las Vegas tracks was completed from Kramer Junction to Joberg. Ore was loaded on to railcars and transported to Barstow for refining. As gold ore went out on the railroad, mining equipment, supplies and water were shipped in. The old right of way can still be seen just to the east of present day Highway 395.\nThe Yellow Aster mine completed its own 30-stamp mill in 1898, and added an additional 100 stamps in 1901. Turn of the century Randsburg boasted 3500 people. Along with the people came the trappings of civilization including schools, fraternal orders and churches.\nThe Yellow Aster continued to be the major mine in the area. In 1911 it was a 24-hour operation employing 250 men. Six million dollars worth of gold had been recovered since the mine's discovery. By 1918, gold production declined. A resurgence of mining activity occurred in the 1930's when gold prices increased. The beginnings of American involvement in World War II marked the closing of the Yellow Aster in 1942.\nMore than six million tons of ore, yielding in excess 600,000 ounces of gold were extracted from the Yellow Aster underground workings. It was the most productive mine of its day in Kern County.\nThe Yellow Aster is again alive with activity. Underground miners with picks and shovels have given way to Caterpillar loaders able to move 13 cubic yards of material in a single bite. Since 1984, Glamis Gold Ltd. has been operating the Yellow Aster, and nearby mines.\nModern mining techniques move huge volumes of material onto a heap where it is treated with a weak cyanide solution. The cyanide leaches the gold from the crushed rock. Gold is later recovered through chemical and electrolytic refining of the \"pregnant\" cyanide solution. During the first nine months of 1997, Glamis reported that 5,193,000 tons of ore were placed on the leach pad. The ore was graded at 0.018 ounces of gold per ton. According to the Glamis' Annual Report (1997), the Rand mining operations yielded 94,243 ounces of gold.\nToday Randsburg is neither a ghost town or a boom town. A branch of the Kern County Museum is occasionally open. Assorted antique stores, a real general store, with maps, books, and prospecting supplies, and the White House Saloon and Floozy House are the principle commercial enterprises along its main street. Residences of varying styles line the towns' few back streets. Randsburg is located off the Redrock-Randsburg Road, about 40 miles north of Mojave.", "domain": "mining_engineering"}

The richest, most concentrated US oil shale deposits are located in Colorado, Utah and Wyoming. These deposits contain approximately 1.2 trillion barrels.\nCurrent oil shale conversion technologies\nBasically, there are two types of oil shale conversion methods, i.e., surface retorting and in-situ process.\nSurface retorting consists of three steps: 1) oil shale mining and preparation; 2) pyrolysis of oil shale; 3) oil refinery.\nThere are two different surface retorting facilities, vertical and horizontal. Vertical retorts heat the oil shale in a vertical vessel. Examples of vertical retorts include Paraho, Petrosix, Fushun, Kiviter. Horizontal retorts heat the oil shale through a horizontal kiln. Examples of horizontal retorts include TOSCO II, ATP, Galoter.\nIn-situ process involves no mining. It is feasible for deeper, thicker deposits, not as amenable to surface or deep mining methods.\nThe most well-known in-situ process is Shell ICP. In this process, a freeze wall is first to be constructed to isolate the processing area from surrounding groundwater. The process releases oil and gas from the oil shale by in-situ heating. The oil and gas then is pumped to the surface using traditional methods.\nAuraSource, Inc. uses a proprietary low-temperature catalytic process (AuraFuelTM Process) for oil recovery from oil shale. AuraFuelTM process is an above-ground retorting technology, which has simple and robust design, energy self-sufficiency, minimal water usage, and high oil yields. By weight of raw oil shale, the oil yield of this technology is as high as 21-28% and it can produce 8-15% of petroleum dry gas to substitute natural gas.", "domain": "mining_engineering"}

This type of needle is the earliest drill bit used in production in my country, and it is also widely used. The working part of the drill bit is a straight-line carbide tip. Practice has proved that the drill bit has simple structure, easy processing and low cost, and is suitable for rock formations with high integrity, so it has been widely used in the process of production and excavation. However, it has certain defects. If the strength of the needle is low, it will wear quickly and easily get stuck, which often causes damage to the needle itself, which affects the progress; the working part of the fiber head is an arc, and the height of the blade arc and the blade is too large, causing damage Easy to scrap. In the process of rock drilling, the outer end of the rotating blade of the needle head has a great effect, but it will not break the rock, and it is easy to form a triangular hole. case, increased wear and tear. In short. Its production effect is not high, and according to the current situation, it has been eliminated. It can only be seen in a few projects.\n②Three-knife drill bit structure. This kind of drill bit is developed on the basis of the original one-shaped type. The structure of the drill bit is a discontinuous needle-blade structure. Since the three-blade Xuan head was developed, many companies have been Through research and development, products based on the basic structure have been continuously introduced, and their forms and materials have also been continuously improved. In the 1980s, a three-edged drill bit was developed. Compared with the three-edged drill bit structure, it has more chipping points and better quality. The tool head matched with carbide material can give full play to the drilling performance, and the geometric shape is also beneficial. Excavation, outstanding anti-wear performance, high speed and not easy to stick, long re-grinding cycle and long life. However, from the manufacturing point of view, its production process is relatively complex, so the wood production is relatively high. Compared with other drill bits, the maintenance of the three-blade drill bit is relatively simple, which can reduce maintenance work during the production process, and also relatively reduce the cost of production organization. Practice has proved that the optimal diameter of the three-blade fiber head should be between 32 and 40 mm, and the rock layers with the highest generation efficiency are brittle rocks and monolithic and fractured rock layers.\n③Cross-shaped drill bit structure. The cross-shaped drill bit also appeared at the same time as the three-blade drill bit. my country was the first to achieve success in the in-line drill bit and the cross drill bit, and it will be designed, applied and produced. In the drill bit series, the cross-shaped drill bit has become an important series of products. The diameter of the cross bit is between 32 and 48 mm, and the blade of the cross bit is improved on the basis of the three-edged bit.\nThe force pieces are arranged in a line. The cross-shaped drill bit with obvious wear resistance can be increased by 30% to 50% according to estimates. The geometry of the in-line drill bit is stable, the processing technology is simple and the quality can be guaranteed, the quality of the fixed piece is easy to guarantee, the broken points of the fiber chisel are easy to operate, and the adaptability to various rock formations is strong. The drill bit can be adapted to the excavation of tough fissures and abrasive rock formations.\n④Ball tooth drill structure. The spherical tooth bit is designed to adapt to high-power hydraulic rock drills, mainly to improve generation efficiency and reduce labor. The multi-tasking carbide insert used in the spherical tooth drill bit has a concentric shape on the drill bit. The wear resistance of spherical teeth is the largest and has higher strength, followed by conical spherical teeth and the lowest, but the efficiency of rock drilling is completely opposite. Therefore, different spherical tooth drill bits should be selected according to different situations in the generation, and the matching situation of the equipment should also be considered. In medium-hard rock formations, one should choose a ball tooth or a bit with a conical tooth. At the same time, it should be noted that the number of teeth is also an important structural parameter. There are many types of ball teeth, and their diameter and number of teeth are also different, so their working conditions are also different. . Practice has proved that the application range of such drill bits is brittle and corrosive rock formations, which are characterized by fast speed, high stability, coarse rock powder and long service life.\n⑤Alloy composite drill bit. Carbide composite drill bits are developed on the basis of a variety of needles, which combine the advantages of flake and spherical drill bits, highlighting the comprehensive performance. The blades with strong rock drilling energy are set on the edge of the drill bit, and the spherical teeth with high rock drilling efficiency are set in the middle, which concentrates the advantages of the above-mentioned various fiber heads. Compared with the traditional one-word, three-blade, cross, spherical and other needles, it has the characteristics of high speed, long life, small grinding amount, stable quality, material saving and low cost. The technical indicators and economic indicators reflected in the application have exceeded those of the traditional drill bit. The measurement of various comprehensive experimental characteristics shows that the drilling stability and speed are good, which is 1.5 times that of the in-line drill bit, and the number of grinding times is significantly reduced; It is 2 to 4 times of the spherical fiber head; the cost of chiseling is also reduced. The cost of the hole with the same diameter is only 1/5 of the flat-shaped drill head and 1/3 of the spherical drill head, and the operation is labor-saving and convenient.", "domain": "mining_engineering"}

The initial assay results from their Phase 3 drill program confirm a significant near-surface lithium pegmatite presence, especially at Big Red and Rocky prospects.\nWithin the verdant terrains of Western Australia, the Kangaroo Hills Lithium Project, managed by Future Battery Minerals Ltd (ASX: FBM), is gaining prominence. The recent Phase 3 drilling results have provided a promising glimpse into the lithium-rich ground, further solidifying FBM’s strategy.\nThe company has reported significant assay outcomes such as:\nFor those unacquainted, “pegmatite” is a type of rock enriched with lithium, among other minerals. A high concentration suggests potential for mining operations.\nFBM’s Technical Director, Robin Cox, shared his enthusiasm, “The initial set of assays from the recent RC and DD program at Big Red and Rocky have delivered further excellent results and confirms the early visual spodumene observations of this emerging LCT pegmatite system. In particular, the result from KHDD006 at Big Red provides further support to the relative consistency in that area of the system in terms of shallow, thick intervals (+20m) at a high lithium grade (+1.2% Li2O).”\n“Recent RC drilling at Rocky (assays pending) has also returned many shallow, substantial intercepts of visual spodumene bearing pegmatites that have significantly increased the scale of this system with assays outstanding. The focus of drilling at Rocky will move shortly to a diamond tail program to commence testing for extension at depth, including the potential for a thickening of mineralisation.”\n“In terms of ongoing scout target drilling, we are seeing encouraging early signs at Wallaroo (West) and further drilling is planned to test the identified pegmatites in this area. The grant of final environmental permitting will also allow us to commence drilling north from Big Red, including other attractive combined resistivity/structural target areas such as Western Grey”.\nWhile FBM has been actively targeting the Big Red and Rocky pegmatite systems, they’re also casting an eye on other regional prospects like Wallaroo. Their drilling program is expected to continue into November, targeting potential extensions at Rocky. This involves a DD program to assess potential down-dip extension or thickening at Rocky.\nBeyond the immediate results, the broader market implications are clear. As the demand for electric vehicles and renewable energy solutions continues to soar, lithium, a key component for batteries, remains in the spotlight. Future Battery Minerals Ltd’s success in Kangaroo Hills is not just a win for them, but potentially an indication of Australia’s bolstered position in the global lithium market.\nHowever, as always, investors should tread cautiously. While assay results provide scientific data on mineral presence, they don’t guarantee successful mining operations or returns. But for now, the horizon looks like it may hold potential for Future Battery Minerals Ltd.\nCurious to learn more about Future Battery Mineral’s story?

A Thermodynamic Cradle-to-Cradle Assessment. By Antonio Valero Capilla and Alicia Valero Delgado. World Scientific, 2014\n\"Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today.\nThis book presents a cradle-to-cradle view of the Earth's abiotic resources through a novel and rigorous approach based on the Second Law of Thermodynamics: heat dissipates and materials deteriorate and disperse. Quality is irreversibly lost. This allows for the assessment of such depletion and can be used to estimate the year where production of the main mineral commodities could reach its zenith. By postulating Thanatia, one acquires a sense of destiny and a concern for a unified global management of the planet's abiotic resource endowment.\nThe book covers the core aspects of geology, geochemistry, mining, metallurgy, economics, the environment, thermodynamics and thermochemistry. It is supported by comprehensive databases related to mineral resources, including detailed compositions of the Earth's layers, thermochemical properties of over 300 substances, historical energy and mineral resource inventories, energy consumption and environmental impacts in the mining and metallurgical sector and world recycling rates of commodities.\"\nThe Threads: Minerals, Economy and Thermodynamics:\nThe Depletion of Non-Renewable Abiotic Resources\nEconomic versus Thermodynamic Accounting\nFrom Thermodynamics to Economics and Ecology\nPhysical Geonomics: A Cradle-Grave-Cradle Approach for Mineral Depletion Assessment\nOver the Rainbow: From Nature to Industry:\nThe Geochemistry of the Earth\nThe Resources of the Earth\nAn Introduction to Mining and Metallurgy\nMetallurgy of Key Minerals\nDown the Rainbow: From Grave to Cradle:\nThermodynamics of Mineral Resources\nThanatia and the Crepuscular Earth Model\nThe Exergy of the Earth and Its Mineral Resources\nThe Exergy Replacement Costs of Mineral Wealth\nThe Exergy Evolution of Mineral Wealth\nTying the Rainbows: Towards a Rational Management of Resources:\nThe Challenge of Resource Depletion\nThe Principles of Resource Efficiency", "domain": "mining_engineering"}

The goal is to lower the cost of these technologies, meet growing demand, and reduce dependence on offshore supplies, DOE said.\n“President Biden’s Investing in America agenda is helping rebuild America’s manufacturing sector by enhancing our ability to produce the critical minerals necessary to develop clean energy technologies,” Energy Secretary Jennifer M. Granholm said in a written statement. “Thanks to these transformative investments, we are reducing our reliance on foreign supply chains while delivering high-quality jobs throughout the communities that have helped power the nation for generations.”\nThe U.S. currently imports more than 80 percent of such minerals from non-domestic suppliers, DOE said. In 2022, the U.S. imported more than half of its consumption of 43 of the 50 critical minerals identified by the U.S. Geological Survey and there was no domestic production of 14 critical minerals, DOE said.\nThe funding will be used to conduct proof-of-concept testing in laboratory or bench-scale facilities to research “economically viable, environmentally benign extraction, separation, and refining technologies.” Such minerals are used in clean energy, national defense, and commercial commodity products and equipment.\nThe funding opportunity is divided into two topic areas: advanced process development for production of rare earth metals and co-production of critical minerals and materials from coal-based resources; and production of critical minerals and materials, excluding rare earth minerals, from coal-based resources.\nThere is potential for advanced processes to produce individually separated, high-purity rare earth oxides and salts and high-purity single or binary rare earth metals at costs about 20 percent lower than currently available conventional separation and conversion technologies, the agency said. The materials will be produced in small-scale pilot facilities that extract and separate critical minerals from coal-based resources.\nThe Infrastructure Investment and Jobs Act authorized appropriations to develop and assess advanced separation technologies for the extraction and recovery of rare earth elements and other critical minerals from coal and coal by-products and determine if there are any environmental or public health impacts from the recovery of these resources.\nOne goal of the program and other DOE-related activities is to help build a domestic supply chain of rare earth elements from a diverse list of resources and establish private investments to create the first domestic midstream processing capabilities for these resources in decades. The supply chain consists of mining, separation, refining, alloying, and manufacturing devices and components parts, DOE said. Forming such a supply chain is essential for domestic self-reliance in this area, the agency said.\nResponses to the funding opportunity are due Oct. 20 Eastern Time, DOE said.\nAll views expressed by the author are solely the author’s current views and do not reflect the views of Concentric Energy Advisors, Inc., its affiliates, subsidiaries, or related companies.

These companies are seeking to develop the hotly contested Pebble Mine, which – if developed – could potentially produce 53 billion pounds of copper, 50 million ounces of gold and 2.8 billion pounds of molybdenum over nearly 80 years.\nAll of these miners are well-positioned to expand their projects further once the transportation infrastructure is in place.\nIn fact, I believe Alaskan copper production could be the next big thing as mining companies look to bring several of these giant projects online over the next few years.\nfor Top Stock Millionaire", "domain": "mining_engineering"}

The mine buildings and processing plants are built, and any necessary equipment is obtained. The operation of the mine to recover the ore begins and continues as long as the company operating the mine finds it economical to do so. Once all the ore that the mine can produce profitably is recovered, reclamation begins to make the land used by the mine suitable for future use.\nMining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.\nTargets are divided into two general categories of materials: placer deposits, consisting of valuable minerals contained within river gravels, beach sands, and other unconsolidated materials; and lode deposits, where valuable minerals are found in veins, in layers, or in mineral grains generally distributed throughout a mass of actual rock. Both types of ore deposit, placer or lode, are mined by both surface and underground methods.\nSome mining, including much of the rare earth elements and uranium mining, is done by less-common methods, such as in-situ leaching: this technique involves digging neither at the surface nor underground. The extraction of target minerals by this technique requires that they be soluble, e.g., potash, potassium chloride, sodium chloride, sodium sulfate, which dissolve in water. Some minerals, such as copper minerals and uranium oxide, require acid or carbonate solutions to dissolve.\nSub-surface mining consists of digging tunnels or shafts into the earth to reach buried ore deposits. Ore, for processing, and waste rock, for disposal, are brought to the surface through the tunnels and shafts. Sub-surface mining can be classified by the type of access shafts used, the extraction method or the technique used to reach the mineral deposit. Drift mining utilizes horizontal access tunnels, slope mining uses diagonally sloping access shafts, and shaft mining utilizes vertical access shafts. Mining in hard and soft rock formations require different techniques.", "domain": "mining_engineering"}

The term Oreb refers to the Ore Body, which is the host rock that contains minerals that are being extracted during mining operations. The lease agreement is a contractual agreement between the mining company and the landowner or government agency that grants the mining company the right to explore, develop, and extract minerals from the Oreb.\nBefore signing an Oreb lease agreement, it is important to understand the terms and conditions that are included in the agreement. The lease agreement should clearly outline the rights and obligations of both the mining company and the landowner or government agency. It should also specify the duration of the lease, the rights of renewal, the amount of rent or royalty payments, and any other fees or expenses that may be incurred during the mining operations.\nOne of the key elements of an Oreb lease agreement is the royalty payment. The royalty is the amount of money that the mining company pays to the landowner or government agency for the right to extract minerals from the Oreb. The royalty can be calculated as a percentage of the value of the minerals extracted or as a fixed amount per unit of minerals extracted.\nAnother important aspect of an Oreb lease agreement is the reclamation plan. The reclamation plan is a plan that outlines how the mining company will restore the land to its original state after the mining operations are complete. The reclamation plan should include details on the specific activities that will be undertaken to restore the land, the timeline for completion, and the estimated cost of the reclamation activities.\nIn addition to the terms and conditions of the lease agreement, it is also important to consider the legal and regulatory framework that governs mining operations in the jurisdiction where the Oreb is located. Mining operations are subject to a range of laws and regulations that are designed to protect the environment, ensure the safety of workers, and promote sustainable mining practices.\nIn conclusion, an Oreb lease agreement is a critical document that outlines the rights and obligations of both the mining company and the landowner or government agency. Before signing an Oreb lease agreement, it is important to understand the terms and conditions of the agreement, including the royalty payment, reclamation plan, and legal and regulatory framework. By carefully reviewing and negotiating these terms, both parties can ensure a successful and sustainable mining operation.", "domain": "mining_engineering"}

In its time, the state-of-the-art milling techniques of the Argo processed over $100 million worth of gold ore!\nThe prices per ounce ranged from $18 to $35, meaning the mill operations were hard at work each and every day. Various techniques were used to extract gold and other minerals, requiring different machines to process the ore diversity. Below, we explore the Argo’s machinery and how it aided its prosperity during the Colorado Gold Rush.\nExploring Milling Techniques – Amalgamation Table\nAmalgamation requires mercury to extract minerals from the rock. To get the gold by itself, the mixture of mercury and gold is heated until the mercury vaporizes, allowing for nearly pure gold to be left behind.\nThis process had been used for centuries before the Colorado Gold Rush, and is still widely used in small-scaling mining worldwide. Efforts to eradicate this practice are in effect, as the high levels of toxic exposure affect both miners and the environment negatively.\nFlotation cells are used in a variety of industries to this day. It is an effective concentration method used to separate finely ground materials. In a mixture of chemicals, water, oil and air, the metallic products would float to the frothy top, allowing any gold to be extracted.\nThe origins of this process were developed in the early 1900s in Australia, and have been refined for commercial use. Introducing flotation technology to the mining industry allowed the supply of low-grade ores to flourish, setting up the industry to prosper globally.\nConcentrating tables utilized simple technology to separate gold ore from other minerals of the Rocky Mountains. The Argo Mill employed seven concentration tables, which vibrated the powered ore to separate heavy and light materials.\nAlso known as gold shaking tables, Arthur Redman Wilfley created the original patented design in 1896 in the U.S. Other variations of this table were created, but the purpose remained the same—it served as the last stop in the milling techniques of The Argo to recover valuable gold that may have been missed during the other concentration methods.\nCyanide Leaching Tank\nThis gold processing method allows for maximum recovery for many forms of gold ores. The cyanide dissolves the gold, which is then extracted from the solution by absorption via carbon or resin granules. Essentially, the cyanide turns the finely ground gold into a liquid form, allowing it to separate from other materials.\nThis process dates back to 1783, but wasn’t introduced to the gold mining industry until 1887.\nOre-Crushing & Grinding\nNone of these processes would have been possible without the machines helping turn the large mined rocks into processable sizes. This was done through the arrastra, the ball mill and the tube mill. Furthermore, stamps weighing over 1,000 lbs were used to pulverize these materials.\nMost of these machines, especially the stamp mill, produced a deafening noise, affecting the miners manning the equipment forever. It was so loud, they called it Thunder in the Valley.\nThe Argo Mill’s three-decade reign is owed to the stellar milling techniques that processed gold ore from the many mining towns near Idaho Springs. They implemented the most recent technologies to yield the highest percentage of precious metals.\nIf you’re fascinated by the history of the Colorado Gold Rush, we can guarantee you’ll enjoy a tour of The Argo Mill & Tunnel. Experiencing the size of Idaho Springs’ mining operations and viewing the milling techniques firsthand will allow you to put yourself in the shoes of a miner in the late 19th century.\nBook your tour today!", "domain": "mining_engineering"}

The stream was the scene of the first discovery of gold in Montana. While the quality of the strike was soon overshadowed by the Bannack strike, it was the Gold Creek mines that first drew prospectors to the region and directly led to the discovery on Grasshopper Creek. Because of its unique position in history, the events leading to the discovery are of more than passing interest.\nIn 1852, Francois Finlay, who was also known as Benetsee, found the first float gold in what is now Montana, in a branch of the Clark Fork, later to be called Gold Creek. His findings became known to the few mountain men in the area, and the stream from which the gold came was called Benetsee's Creek. Angus McDonald, in charge of Fort Connah near Flathead Lake, had some of the dust Benetsee found assayed, and reported the discovery to the Hudson's Bay Company in Victoria, British Columbia. With the California gold rush only three years old, the Hudson's Bay Company well knew what would happen if news of the gold strike were to get out. To prevent prime beaver grounds from being overrun by gold-seekers, McDonald was ordered to keep the dust a secret.\nOne year later John Mullen and other members of the U.S. Government-sponsored Stevens railroad expedition were said to have washed some flakes from Benetsee creek. Popular tradition and nearly every historical source states that Mullen knew nothing of Finlay's discovery and so renamed the stream Gold Creek after finding the gold. However, Mullen and Finlay's daughter, Mary Ann, were apparently well-acquainted. Peter Mullen, Mary Ann's first child was born not long after the expedition. Whether Mullen actually panned the gravel of Gold Creek or merely noted it after hearing about it, Mullen's name became linked with that of Gold Creek. At the time, little was made of the discovery, the expedition report notation of gold in a remote northern stream could hardly compete with the banner headlines heralding vast gold strikes and the reality of tons of gold dust coming out of contemporary California (Mullen 1991).\nThe stream was next prospected in 1856 by a group of miners led by Robert Hereford. The group included John Sanders (known as Long Tom), Bill Madison and a couple of others. The party of men was enroute from the Bitterroot valley to Salt Lake City when they apparently heard of Gold Creek and did some panning there. Some gold was found, but not enough to slow the men. When they connected with the California Trail just west of Utah, they stopped and talked with Granville Stuart, James Stuart and Reece Anderson; the trio were on their way back from the California mines. The Stuart-Anderson party was cooling their heels in camp waiting for the dust to settle on the Mormon War so they could proceed across Utah safely. When they saw the gold dust of Hereford and company, they altered their plans to take a side-trip to Gold Creek. Although the Stuarts tried to work the stream early in the spring of 1858, the lack of tools brought a halt to the operations. Stuart built a log cabin on the Mullen Road where it crossed Gold Creek. This cabin became the nucleus of a small community named American Fork where 45 people lived and conducted an active trade of goods (Pardee 1951).\nIn 1860, Henry Thomas (also known as Gold Tom) dug a 30-foot shaft in the glacial till of Gold Creek at a point about one mile west of what later became known as Pioneer City. The small prospect returned $1.50 a day from axe-hewn sluices. However, the gold was little return on the effort involved in producing home-made mining equipment. It was, however, enough to push Stuart into obtaining the means to properly work the gravels of the stream. In the spring of 1862, miners were hurrying through the area from the head of navigation on the Missouri to the new Idaho mines. From them Stuart obtained the tools necessary to work the stream. On May 8 1862, Granville Stuart set up the first effective sluices in Montana. When he found gold, the news was not lost on the prospectors passing through the area. A party of prospectors arrived on May 14 and found diggings that paid 20 cents per pan. On May 20 another party arrived and prospected along a branch of Gold Creek which they named Pikes Peak Creek. On June 1, yet another group of prospectors arrived on the scene and found gravel that paid about $10 to the man by working the stream with sluices (Pardee 1951).\nMiners on the way to diggings such as Stuart's often stopped and panned the streams along the way. In such a manner John White came upon the fabulous placers of Grasshopper Creek. When word of the rich strike arrived at Gold Fork, the miners left for more promising operations. By August 1862, only four months after the first sluices were in place, the Gold Creek placers were nearly abandoned; only two men remained to work the gravel. There followed a dizzying number of fabulously rich strikes at Alder Gulch, Last Chance Gulch, Confederate Gulch and many others. Gold Creek became a backwater and the town of American Fork was abandoned (Pardee 1951).\nThere was little activity on Gold Creek until 1866, when the Pioneer mining district was organized. The placers of Pioneer Creek and its tributaries, French and Squaw gulches, soon overshadowed the initial placers on Gold Creek. Under laws of the new district, bar claims of 200 feet running back to the summit of the hill could be made. In 1867, the Pioneer Company began using hydraulics on the bars. Although no rush ensued, mining activity picked up and the population of the Pioneer district rose to a high of 1000. Most of the population was concentrated in the new camp of Yam Hill near Batterton Bar.\nLack of water was more of a problem than the apparent lack of gold. In 1868 or 1869 Conrad Kohrs and others, formed the Rock Creek Ditch Company, to build a 16 mile canal to deliver water from Rock Creek to the Pioneer, Willow Creek, and Pikes Peak districts. The system initially delivered water to the Gold Hill terraces; the first terrace to be worked was the slope descending down to Pikes Peak Creek. These terraces contained rich gold deposits. Several hundred men worked the placers and a reported $140,000 was recovered in a single season from a pit on Batterton Bar. By 1870, it was estimated that $20,000,000 in placer gold had been taken from the gulches (Pardee 1951; Wolle 1963).\nThe Pioneer district never rivaled the other major strikes of Montana, but just the same the district flourished all through the 1870s. New placer deposits were discovered and developed at French Gulch, Squaw Gulch, Woods Flat and Wilson's Bar. By 1874 the richer parts of the terraces had been worked, but new deposits were discovered at Pioneer Bar and Ballard Hill. As these placers grew, the town of Yam Hill became deserted and a new town of Pioneer City began to grow. It has been estimated that over a million dollars of gold dust (at $20.67 per ounce) was removed from the Pioneer Bar in the late 1870s and early 1880s (Pardee 1951; Wolle 1963).\nAround 1875, Conrad Kohrs, a stockman and trader who had been involved in the Rock Creek Ditch Company, bought up a number of mining claims and water rights in the Pioneer district, planning to leave them to his son as a legacy. His plans failed to materialize, for his son died and he quit mining. Another man, Tim Lee, brought a company of 800 Chinese miners to the gulch. He directed these laborers for several years. They worked to wash gold from the tailings and carried away the waste rocks in baskets to restack it on new dumps. When they could no longer recover any gold, they left the area.\nPrior to 1890 the deposits on Pioneer Bar and at the Ballard mine were nearly worked out, but extensive hydraulic operations were being conducted at the K & K Bar, a low terrace in Pioneer Gulch. This operation was conducted by F.J. Slaughtner for the owners, Kohrs and Bielenberg. The hydraulic operation continued until 1918 (Pardee 1951).\nIn the 1890s, an English syndicate, the Gold Creek Mining Company Ltd., sank test holes in the gravel and began to work the ground with a small dredge. The dredge proved too small and light in construction to deal with the deep, bouldery gravels and efforts stopped after a shallow trench was excavated. The English Company also met resistance from some of the older residents of the district, including Conrad Kohrs, who cut off their supply of timber and water. The company ceased work and filed suit against the hecklers. The case dragged on for many years and was not settled until 1927, when Pat Wall, a miner from Butte, offered to buy the English Company's holdings. He bought up 3,200 acres held by the Kohrs-Bielenberg interests, which included water rights and the townsite of Pioneer. These two purchases, which gave him 7,000 acres of placer ground, permitted him to plan big-scale dredging on 6,500 acres and hydraulicking on 500 acres more.\nBetween December 1933 and June 1939, the Pioneer Placer Dredge Company, Inc., recovered a gross total of $1,374,631 from these gravels. The company used a sturdy \"California-type\" electric chain-bucket dredge.\nProduction figures for the creeks of the district have generally been combined reports, so a fair and accurate estimate of the production of each creek cannot be made. The total production of the placer mines in the district, up to 1949, was estimated to be $28,526,000. An estimate of about $7,000,000 seems to be fair and conservative for the total production of placer gold from the Pioneer district from 1860-1945, because the \"cream had been skimmed\" from the richest bars prior to 1898. In fact the dredge at Pioneer held first rank as a gold producer in Montana in 1934. Although primarily a placer mining district, some lode mines have been developed at the head of Gold and Little Gold Creeks. Most of the lode mines, however, are in Granite County (Sahinen 1935; Lyden 1948; Wolle 1963).\nIn addition to the efforts of Pat Wall and the Pioneer Placer Dredge Company, other smaller mines continued to work in the early 20th Century. Prior to 1920 the west side of Gold Hill was reworked in the Squaw Gulch pit. In 1920, the Rock Creek ditch and its water rights were purchased and diverted to water fields. Water was then brought into the district from Pikes Peak Creek and used to work deposits on Gold Hill above the Rock Creek ditch. The largest of these workings were the Kelley and Irvine pits. For several years after 1920, hydraulic operations were conducted on the gravels of Pioneer Gulch at the foot of Ballard Hill. This deposit had been missed by earlier efforts because of a heavy talus overburden (Pardee 1951).\nOn the upper parts of the middle and east forks of Pioneer Gulch as well as on China Bar, Chinese miners worked the gravel prior to 1930. The amount of gold production is not known, but may have been large.\nGold Creek and Pikes Peak Creek flow into an area of complexly folded and faulted Mesozoic and Paleozoic sediments which have been intruded by an elongated batholith of quartz monzonite. The lode deposits occur in veins and replacement deposits in highly altered granite or quartz monzonite. None of the lode deposits have been particularly important as points of production, but erosion of these gold-bearing deposits have resulted in extensive placer deposits in Gold, Little Gold, Pioneer, and Pikes Peak Creeks. The placer gold occurs in recent stream gravels and also in bench gravels. The deposits have been mined by sluicing, hydraulicking, and dredging (Sahinen 1935).\nNo production figures are available prior to 1904 when the majority of the gold was recovered from the district. However, from 1904 to 1951, the operations in the district worked 4,625,700 cubic yards of gravel to recover 65,000 ounces of gold and 7,442 ounces of silver. Estimated value of historic Twentieth century production was reported to be over $2,000,000. Most of this production occurred in the 1930s with the advent of dredging (McClernan 1976).\nBOUNDARIES OF THE DISTRICT\nSahinen (1935) places the district southwest of Gold Creek, a station on the Northern Pacific and Chichago, Milwaukee, and St. Paul Railroads. Figure 1 shows the historic mining district as defined by Sahinen (1935) which includes the primary creeks and gulches which were the scene of the placer activity.\nHISTORIES OF SELECTED MINES\nFrom 1909 to 1930, the Friday mine reported production in 19 years (WPA 1941).\nGold Creek Placer\nThe Gold Creek placers during the Twentieth century reported production intermittently from 1905 to 1910 and again in 1930 and 1931. The mine was discussed in the mining literature in 1904 and 1905 and again in the 1930s (WPA 1941).\nThe Gold Hill placers can be divided into two areas, the north portion which was called the Squaw Gulch pit and the southern portion which contained the Kelley and Irvine pits. The area around the Squaw Gulch pit was worked early in the history of the district. Extensive workings were excavated on the western side of Gold Hill above the steep slope to Squaw Gulch. The Squaw Gulch gravels were prospected in 1931 by the Henderson Mining Co., but no paying ground was found. The Kelley and Irvine pits contained gold in an unsorted mass of boulders, cobbles, sand and clay. The pits were reported to have produced $20,000 in gold. No production figures are available for the larger Squaw Gulch pit. Other small gulch and ravine placers have also been worked on Gold Hill (Pardee 1951).\nThe Independence mine is located on Windy Hill. Although the vicinity was worked in the district's early days, no production records have survived. The mine next reported production nearly every year between 1926 to 1930. The gold was of exceptional purity, assaying at 968 fine. The rough angles on the gold recovered indicated that the gold was little water worn, having been deposited by glacial action (WPA 1941; Pardee 1951).\nK & K Bar\nLocated on the east side of upper Pioneer Gulch, the K & K Bar stretches nearly a mile and a half in length with varying width. The workings on the lower third of the bar was collectively known as the Kohrs and Kelley mine. The upper two-thirds of the bar was known as the Kohrs and Bielenberg mine. In 1916 the upper workings were extended 600 feet; the area is known as the 1916 pit. From it 711 ounces of gold were recovered. Work continued in the pit until leaner gravels were encountered in 1918 (Pardee 1951).\nThe Oro Fino was active intermittently from 1909 to 1929 (WPA 1941).\nPikes Peak Creek\nPrior to the advent of dredge operations in 1934, nearly half of the gold recovered in the district came from the Pikes Peak placers. The Batterton Bar in the district produced $140,000 in a single season. Gold was found in small particles with some nuggets up to $10 in value. The gold assayed at $17.75 an ounce at a time when pure gold ran $21.67. Some gold from the Larrabee Bank ran as high as $18.60 per ounce.\nPart of the pay streak was mined by drifting, but this area was covered by waste rock from mines higher on the hill. Below Treadwater Bar, a 3,000 foot segment of recovered pay streak was worked by a dragline shovel and a dry-land washer (Pardee 1951).\nThe Pioneer property was active in 1916 and again from 1928 to 1931. The mine was discussed in the mining literature during the latter period of production (WPA 1941).\nIt has been estimated that over a million dollars worth of gold was taken out of six gravel terrace channels on a spur west of Pioneer Gulch. Bank records indicated that the gold assayed at $18.50 per ounce. The Pioneer placer was active 18 years from 1910 to 1938 (WPA 1941).\nPioneer Placer Dredging\nThe Pioneer electric dredge reported production from 1933 until the operation was stopped by Federal order at the advent of World War II (WPA 1941; Pardee 1951).\nThe Montana Bureau of Mines vertical files list the following placers: Dawson, Dry Creek, Fin de Siecle, Fowler Tibbetts, French Gulch, Gold Hill, Hart's Gravel, Middle Falls, Prowse Par, Rocker Gulch, Squaw Gulch, Trail Gulch, Wilson's Bar, Windy Bar, Wood's Flat, and Yam Hill (Pilgrim's Bar).\nBowman, A.

Marks\nJohn R. Marks, Jr. was born and raised in Wisconsin. In 1966, the Marks family moved to Boise, Idaho where he attended and graduated from high school. Marks earned a bachelor's degree in mining engineering at the University of Idaho in 1973 and began his mining career as a junior engineer at Hecla Mining Company in the Silver Valley of north Idaho. He did surveying, mine planning and design at the Star Mine and ventilation engineering for the Star and Lucky Friday mines.\nFrom 1975 to 1977, he continued his education at the University of Idaho as a graduate student and served as an instructor and tutor. Marks completed his thesis, “Computer-Aided Design of Large Underground Direct-Contact Heat Exchangers” in 1990 and earned a master's in mining engineering.\nIn 1977, Marks returned to Hecla Mining Company as a mining and ventilation engineer where he was responsible for all ventilation and refrigeration at the Star, Lucky Friday and Con Sil Mines. He Became a senior mine engineer in 1980 and was responsible for all mine engineering functions at the Lucky Friday Mine.\nFor the next 19 years, Marks worked for the Homestake Mining Company in Lead, S.D., as a ventilation engineer, then as the chief ventilation and health engineer. The former Homestake mine is 8,000 feet deep and contains 370 miles of tunnels. Between 1876 and 2003 the Homestake Mine produced 42 million ounces of gold worth about $3.5 billion. Marks was responsible for all ventilation and refrigeration at all levels of the mine. He designed and installed a 3,000 horsepower (hp) surface fan, a double 1,000 hp underground booster fan and a 2,300 ton refrigeration plant utilizing controlled recirculation. In 1996, he worked on assignments including shaft design, strategic planning, pumping, ore haulage, waste rock removal and refinery ventilation.\nIn 2001, Marks worked at Stillwater Mining Company in Nye, Mont., as a consulting engineer planning ventilation requirements and designing a $10 million system upgrade for the Stillwater platinum/palladium mine. A year later he joined the engineering transition team for the National Underground Science Laboratory facilitating the conversion of the Homestake Mine into a science laboratory. Plans are now under way to turn Homestake into the first national laboratory for underground science in the United States — and the largest and deepest facility of its kind in the world. Scientists hope to use the lab in the mine for an experiment to find out what role neutrinos played in the evolution of the universe. It is one of more than 40 scientific experiments scientists already have proposed for the new laboratory.\nFrom 2002 to present, Marks has been a mine ventilation consultant. He is presently consulting for the South Dakota Science and Technology Authority on the conversion of the Homestake Mine into the National Deep Underground Science and Engineering Laboratory (DUSEL) and has consulted with, and/or continues to work with many other mines in South Africa, Bulgaria, three Canadian provinces, and U.S corporate offices for mines in Guatemala and Indonesia.\nMarks served as an adjunct professor for the South Dakota School of Mines and Technology in Rapid City, S.D., teaching mine ventilation. He has taught seminars at most western mining schools in mine economics and mine ventilation, air conditioning, computer applications and diesel use. He has authored or co-authored over 25 papers in mining, including chapters in ASHRAE’s 2003 & 2007 Applications Handbooks, a mining textbook, and the new Society of Mining Engineer’s (SME-AIME) 2011 Mining Engineering Handbook. In 1992, he was Chairman of Society of Mining Engineer’s (SME) Underground Ventilation Committee. He holds several professional memberships including Tau Beta Pi, the National Engineering Honor Society. He received the Black Hills Safety Professional of the Year honor and in 2008, was awarded the prestigious SME’s Hartman Award for excellence in mine ventilation.", "domain": "mining_engineering"}

The factory provides comprehensive mineral processing and produces three concentrates: iron ore, apatite and baddeleyite.\nKovdorsky GOK has been consistently upgrading the entire equipment fleet to enhance its capacity and performance.\nThus, the upgrade called for replacement of obsolete coarse and medium/fine crushers in order to improve performance, quality of the output and reduce scheduled and emergency downtime.\nProfessionals of Sever Minerals and Metso studied the objectives for the new equipment and operation conditions in detail. Ore samples were sent to Metso laboratory in Finland to establish physical and mechanical properties of the feed. As a result, the most appropriate solution, which guaranteed that the client would reach the required performance and crush size included several projects:\n- Supplying three Metso С200 jaw crushers and grizzly screens for coarse crushing;\n- Supplying two Metso НР500 cone crushers for medium/fine crushing;\n- Supplying an apron feeder and roller grizzly feeder for medium/fine crushing.\nSince their commissioning in 2016, HP500 crushers have been successfully operating for three years. The commissioned equipment allowed to double the capacity of medium/fine crushing. It reduced operating expenses - specific costs for lining, spare parts, power, maintenance and repairs.\nCoarse crushing upgrade projects started in 2016, when the first С200 crusher was installed. The project is now in its final phase, installation and commissioning of the second С200 crusher with a pre-screening grizzly is complete, installation of the third will start shortly.

The volcanic eruptions millions of years ago forced the diamonds up to the surface where they were scattered along oceans and rivers.\nThe first diamonds were thought to be discovered in India around 800 B.C. No one ever discovered the volcanic eruption that it came from but the river bed deposits were plentiful enough to supply most of the word’s diamonds up till the 18th century.\nThe word diamond comes from the Greek word “adamas”. It means unconquerable in reference to the eternity of love. In 1477 Archduke Maximilian of Austria put the name to the test when he gave a diamond ring to Mary of Burgundy when he wanted to marry her. This started the tradition of diamond engagement rings which became all the rage at the time and hence started the popularity that diamonds experience today.\nThe largest amount of gem quality stones are found in South Africa but they are also discovered in Russia, South America, and the United States. The mining outside of South Africa produces industrial quality diamonds mostly. In 1866 one of the first South African diamonds was discovered by a young boy along the banks of Val River. It was a 21 carat gem that later became part of the gavel used by the Premier of South Africa.\nAfter this discovery many diamond diggers began finding other diamonds along in the Val and Orange rivers. Below this yellow earth a layer of blue-gray rock called “blue ground” or “kimberlite” was discovered. This 60 mile coast of the Orange River divides South and South West Africa is owned by Consolidate Mines of South West Africa which is part of the DeBeers group, which have produced almost 1 million carats of diamonds a year since 1956.\nThe largest diamond bearing “blue ground” is in Murfreesboro, Arkansas. This is where the largest diamond was ever discovered in the United States. It was named “Uncle Sam” and was a whopping 40 carat stone. Murfreesboro Mine has become quite the tourist attraction because of this and has yielded over 60,000 diamonds since it was first discovered in 1906.\nOnly about one-fifth of the diamonds that are mined can be considered gem quality once they are discovered. Depending on how deep the diamond is found it make take the processing of 40 to 250 tons of gravel and sand to recover just one rough diamond from the world’s thinning diamond deposits.\nIt is a long process that ends with the separation of diamonds by size, shape, and quality. Only 20% to 25% are actually made into jewelry, most are used in industrial applications such as drilling, grinding, and sawing. Within 30 to 40 years experts think that all known supplies of diamonds will be completely depleted.", "domain": "mining_engineering"}

BCMM# 13484\nPrior to the stock market crash in October 1929, the Mill at Britannia produced peak volumes of chalcopyrite (the major ore of copper) and wealth for both the British Columbian and Canadian economies.During this period, the Mill was processing up to 6500 tons (14,000,000 pounds) of rock daily. That’s as much weight as 480 elephants every day!\nThe main function of the Mill was to separate the waste rock from the minerals (mainly chalcopyrite) that the mining company wanted to sell. All the ore was ground up to the consistency of flour and put through a chemical process known as froth flotation, which causes the valuable minerals to rise to the top and the waste rock to fall to the bottom.\nThe ore at Britannia Beach was rich in copper. It contained an average of 1.25% copper or 25 pounds of copper for every ton of ore. After the ore went through the Mill, the end product was 26% copper, or 520 pounds per ton. This was very efficient. Britannia’s froth flotation process was so widely used that it became known as the Britannia deep cell method.\nThe more ore that was processed the more money the mine made. To maximize profits, the methods of separation within the Mill were constantly being updated and improved. Every year the process would change slightly to yield greater amounts of ore. The Britannia Mines Mill earned a reputation as one of the most productive mills in the world.", "domain": "mining_engineering"}

However, mining operations also face unique challenges, particularly with regard to potentially dangerous gases that can accumulate in underground environments. To ensure that miners are able to work safely amidst these potential risks, the gas detectors play an integral role in mine safety management. Fixed and portable gas detectors have become two of the most important tools for mine safety, playing unique and critical roles in continuous monitoring and mobile monitoring respectively.\nFixed gas detectors can be installed throughout the mine to continuously monitor the environment for the presence of harmful gases such as Methane (CH4), Carbon Monoxide (CO) and Hydrogen Sulfide (H2S). Fixed gas detection systems are equipped with an alarm function that is automatically triggered when harmful gas concentrations are detected above preset safety limits. For example, if an abnormal gas concentration is detected during a mining operation, an alarm is automatically raised and safety measures are initiated. In addition, fixed systems can remotely shut down an area, isolating the hazard and ensuring the safety of all personnel in an emergency.\nPortable gas monitors have a small size and weight that miners can carry with them. These devices can detect in different locations in the mine, including tight and hard-to-reach areas. Before entering the working area of a mine, miners often use portable gas detectors to conduct tests. This can help them determine if there is a leak or build-up of hazardous gases. If the presence of hazardous gases is detected, miners can take the necessary precautions before entering the mine, such as ventilating or waiting for the gas concentration to decrease.\nWhat are the Dangerous Gases in Mines?\n- Methane (CH4): Methane is also known as gas, is one of the most common hazardous gases found in underground mines. It is a colorless, odorless gas that is highly flammable and explosive. Methane is usually released in coal and other mines and accumulates to a certain concentration where mixing with air may cause explosions and fires.\n- Carbon Monoxide (CO): Carbon Monoxide is a colorless, odorless gas produced by incomplete combustion. Carbon Monoxide may be produced in mines by explosions, engines and combustion equipment. It binds to hemoglobin, reducing the Oxygen carrying capacity of the blood and posing a hazard to the human body.\n- Hydrogen Sulphide (H2S): Hydrogen Sulphide is a pungent-smelling gas often described as \"a rotten egg smell\". It can be perceived even at low concentrations. High concentrations of Hydrogen Sulfide are harmful to the respiratory system and the central nervous system and can lead to poisoning, vomiting, headaches and coma.\n- Nitrogen (N2): Nitrogen may accumulate in mines due to poor ventilation or other reasons, leading to hypoxia. Oxygen deprivation can cause breathing difficulties, dizziness and weakness.\n- Volatile Organic Compounds (VOC): The release and breakdown of organic substances to form VOCs can occur as a result of microbial decomposition, underground mining activities, the nature of the ore and groundwater, etc. These compounds sometimes accumulate in mines and may have health and safety implications for miners, including respiratory irritation and headaches.\nWhich Gas Detectors are Used in Mines?\nSingle Gas Monitors\n- Methane (CH4) Gas Detector: It detects the build-up of Methane and sounds an alarm if the Methane concentration exceeds safe limits. Methane gas detectors help maintain CH4 concentrations within safe limits and reduce the risk of explosion.\n- Carbon Monoxide (CO) Gas Detector: In underground mine operations, use a CO gas detector can monitor the concentration of Carbon Monoxide in a timely manner and raise an alarm once the concentration exceeds the safe limit, safeguarding the safety of miners.\n- Hydrogen Sulfide (H2S) Gas Detector: Hydrogen Sulfide is a toxic gas that can affect miners' health even at low concentrations. Hydrogen Sulfide gas monitors can detect H2S in advance to ensure the safety of miners.\n- Oxygen (O2) Gas Detector: In the mines, too low a concentration of Oxygen may lead to asphyxiation, while too high a concentration of Oxygen may cause a fire or explosion. Oxygen gas detectors can provide timely alarms and remind miners to take necessary measures.\nMulti Gas Monitors\nMulti gas detectors are very important safety tools in underground mines, helping miners and managers monitor gas conditions in real-time, ensure the safety of the mine environment and take the necessary measures to deal with potential gas risks. Multiple gas monitors are capable of simultaneously monitoring a wide range of hazardous gases such as Methane (CH4), Carbon Monoxide (CO), Hydrogen Sulfide (H2S), Oxygen (O2) and more. This integrated monitoring helps miners and managers obtain more comprehensive gas data to assess the safety of the mine environment.\nIn mines, using gas monitors is critical, whether fixed or portable gas detector equipment. Fixed gas detectors are typically used for long-term monitoring and control of gas concentrations in underground environments, whereas portable gas monitors provide a more flexible means of enabling miners to detect gases in real-time while on the move. Through the combined use of both instruments, mine workers are able to comprehensively monitor gas conditions in the mine environment, thereby reducing the risk of accidents and safeguarding the health and safety of miners.", "domain": "mining_engineering"}

Based on it, the company’s UG67 outdoor LoRaWAN gateway serves as an interface between the air quality sensor and the cloud platform.\nNature of Disruption: In the mining sector, wired networking has a restricted range, high cost, high maintenance cost, and vulnerability. Short-range technologies, such as Wi-Fi and Bluetooth, do not cover a large enough area, have significant power consumption, and are unable to penetrate deep under the mine environment. LoRa’s deep penetration capability enables data transfer over a long distance while using very little power, making it suitable for smart underground mining applications. The smart ventilation system is intended to meet the aim of dynamic ventilation system control based on hazardous gas concentration measurements. Air quality sensors are used to measure concentrations of CO2, CH4, CO, SO2, H2S, NO2, and other pollutants. Monitoring gas concentrations allows for adaptive ventilation management. The Milesight UG67 LoRaWAN gateway receives data from sensors and transmits it to the management center. As a consequence, the control center may either switch on the ventilation fan to dilute and eliminate pollutants or turn it off to save energy. LoRa’s technology is IP 67 waterproof, uses Semtech SX1302, and has full-duplex radios in its arsenal. This with round-the-clock real-time monitoring reduces downtime after-blast and lessens energy consumption by up to 50%.\nOutlook: Mining has long been a major primary sector business in many nations, including Australia. In underground mining, ventilation is the foundation of oxygen supply and the principal way of eliminating hazardous gases. The majority of ventilation systems are built for “worst-case scenarios,” and mine managers frequently operate their ventilation systems at this maximum level without regard for real ventilation demand. As a result, ventilation accounts for a tiny portion of total subterranean energy consumption, although the majority of them are redundant. As a result, it is important to create a ventilation-on-demand system to decrease energy usage while maintaining a safe working environment. The adoption of smart environmental data accumulation and ventilation control systems in underground mines, on the other hand, remains difficult. As a result, Milesight devises a solution to improve smart ventilation management for underground mining using LoRa technology to meet the issue.\nThis article was originally published in Verdict.co.uk", "domain": "mining_engineering"}

This can be accompanied by increases in concentrate grade also.\n- ProFlote can be Retrofitted to Existing Plants\nAll current ProFlote installations are in existing plants. Positioning of ProFlote is flexible within the plant.\n- ProFlote Operating Costs are Negligible\nProFlote requires a small amount of 80-100psi compressed air. No other utilities are required giving the ProFlote a negligible operating cost.\n- ProFlote has a Small Installation Footprint\nDepending on plant size and throughput, the ProFlote required for a plant has only a relatively small footprint, making locating of the ProFlote simple.\n- ProFlote Installation is Simple\nThe only requirement is that the flotation feed pass through the ProFlote. ProFlote is supplied with flanged fittings making installation in existing pipe work straightforward, alternatively ProFlote can be installed in existing conditioning tanks.\n- ProFlote Generates Large Financial Benefits.\nWith negligible operating costs, simple installation and large improvements in mineral recoveries ProFlote generates large financial benefits in saleable metal.", "domain": "mining_engineering"}

It assessed the mining companies’ practices in terms of the following aspects: legal, technical, environmental, social and economic.\nThe MICC review categorized mining companies’ practices into:\nMinor Corrections 2\nMajor Reforms 1\nNot Acceptable 0\nThe rating system provides a snapshot of the assessment after the Review Teams conducted their field visits, performed their analyses, and discussed with team-members and co-specialists.\nIn order to separate the mining companies that had the most problems from those with fewer issues, a 1.5 cut-off average score per aspect was determined as the threshold. This cut-off is fifty percent of the highest score of 3 as an acceptable level of performance.\nAmong the 26 mining companies, four, or 15% of the total, have legal rating that are lower than 1.5 - Zambales Development Mining Corporation, Claver Mining Development Corporation, Oriental Synergy Mining Corporation, and Mt. Sinai Mining Exploration and Development.\nFour mining companies, also 15% of the total, have technical scores that are lower than 1.5 - Claver, Oriental Synergy, SinoSteel, and Ore Asia.\nOn the environmental aspect, eight (8) companies scored below the passing rating of 1.5. They are Claver Mineral Development Corporation, Wellex Mining Corporation Mine 1, Libjo Mining Corporation, Oriental Synergy Mining Corporation, Oriental Vision Mining Phil. Corporation, Sinosteel Phil. N.Y. Mining Corporation, Krominco Inc. and Ore Asia Mining and Development Corporation\nThe social aspect of the review showed that twelve (12) companies scored below the threshold. These are Benguet Corp.

Sinai Mining Exploration and Development, Emir Minerals Corp., Ore Asia Mining and Development Corporation and Strongbuilt Mining Development Corporation.\nIn terms of the economic aspect, only two (2) companies scored lower than the threshold. They are Oriental Synergy Mining Corporation and Ore Asia Mining Development Corporation.\nBased on the Report, three (3) mining companies are most problematic for majority of the aspects reviewed. Three (3) companies, Claver Mineral Development Corporation, Oriental Synergy, and Ore Asia, have three to four average aspect scores that are less than 1.5. DENR Secretary Roy Cimatu issued order affirming the cancellation of the MPSAs/denial of MPSA application of these companies.\nThe MICC Report also includes case studies on the Economic Analysis of Specific Options for Selected Mining Companies. They are:\n• Benguet Corporation, BC (gold mining) – alternative uses of the inactive Antamok for Benguet Water Supply or Engineered Sanitary Land Fill\n• Oriental Vision Mining Philippine Corporation, OVMPC (nickel mining) in Dinagat Island – land use alternatives (agro-forestry)\n• Hinatuan Mining Corporation, HMC (nickel mining)– alternative land use to mining in a small island setting\n• Zambales nickel mines: Benguet Nickel Mines, Inc., BNMI; Eramen Minerals Inc., EMI, LNL Arhipelago Minerals, LNL Archipelago Minerals, In. LAMI; Zambales Diversified Minerals, ZDMC – management of silt that drain into common water bodies\n• Strongbuilt Mining Development Corporation (magnetite/iron) – alternative scale combined with agricultural crop production\nThe Report generally showed that for the majority of mining companies, improvements in technical and environmental management practices need to continue and scale up.\nIt should be noted that the Report also acknowledged that there had been efforts by at least half of the companies to rectify and correct inappropriate practices.\nSome policy recommendations mentioned in the Report include the development of guidelines for Care and Maintenance Period, retooling of the Multipartite Monitoring Team, implementation of a “one-stop” for mining permit and document processing, and the determination of minerals in direct-shipping ores (DSOs).\nSec.

Traditionally, grinding ball have been widely used for various milling and industrial processes. These included hardened carbon steel, chrome steel, stainless steel, forged steel, etc. While steel has traditionally been used for the purpose of industrial grinding balls, it is fast being replaced by tungsten as the preferred material. Tungsten is used as both tungsten alloy as well as tungsten carbide for making high hardness and excellent strength grinding balls for various industrial applications such as mining industry. However, with the change of technology, more modern nonmetallic products with superior qualities like tungsten carbide grinding ball are used in oil industries and offer multiple advantages of high hardness, anti-abrasive & corrosion and excellent strength in comparison to the traditional options, it has longer lifespan involving industries contribution. What’s more, tungsten carbide spherical is most cost efficient hard facing materials, for long running, it brings good economic effectiveness used in oil industry and will widely spread to greater benefit.\nTungsten carbide grinding balls are used to homogenize large and resilient products which be managed with the help of smaller grinding beads. Tungsten carbide grinding balls are spherical with varying diameter ranges. While steel is also used for the same purpose, tungsten carbide grinding balls for the oil industry is highly demanded owing to their high density and hardness along with other features like abrasion resistance.\nFeatures of Tungsten Carbide Grinding Balls\nTungsten carbide grinding balls are available in different sizes ranging from 0.4mm to 4” along with a high precision G3 and a density higher than steel ranging from 15 g/cm3, hardness 92.5 WELSON is the leading manufacturer and supplier of tungsten carbide grinding balls for oil industries around the globe.

These include the sintered tungsten carbide balls, the rough grinding tungsten carbide balls, the grinding tungsten carbide balls, the high precision tungsten carbide balls, and the smooth grinding tungsten carbide balls. Usually produced with grade YG6 and a hardness level of HRA91.0, these are widely used in the oil industry for different grinding and milling applications.\nWhat Makes it Better Than Steel?\nFurther, some of the key features which make tungsten carbide balls a favorite within the oil industry include: 1. High-cost effectiveness due to low wear and minimal maintenance 2. High efficiency 3. High specific gravity 4. High hardness to meet the crushing and grinding requirements within the industry 5. Highly polished, easy to clean 6. Resistant to high temperatures, abrasion, etc. The use of tungsten carbide grinding balls for the oil industry, although costlier than traditional materials like steel is still being considered as more cost efficient in the long run owing to its long life span and low maintenance requirements.", "domain": "mining_engineering"}

We’re running out of new sources, and breakthrough technologies that have changed the way we use other goods haven’t happened for copper.\nUp till now\nA US startup says it has solved a puzzle that has been puzzling the mining world for decades. If true, this could change the way the world gets its supplies.\nIf it works, Jetti Resources’ discovery could lead to millions of tons of new copper that could be used in power grids, construction sites, and car fleets all over the world. This would help narrow or even close the deficit.\nJetti’s technology is based on a common type of ore that holds copper behind a thin film, making it too expensive and hard to get out. Because of this, over the years, huge amounts of metal have been left behind in mine waste piles on the surface and in untapped deposits. Jetti has created a special catalyst that breaks up the layer and allows microbes that eat rocks to get to work on freeing the copper.\nLarge-scale testing of the technology is still needed. But the money at stake is bringing in some of the most powerful people in the business.\nSources say that the biggest mining company, BHP Group, is already an investor and has spent months negotiating for a trial plant at Escondida, Chile’s crown jewel copper mine.\nThis year, Freeport-McMoRan Inc., a US mining company, started using Jetti’s technology at a mine in Arizona. At the same time, Rio Tinto Group, another US mining company, plans to roll out a similar but different process.\nThe miners are trying to solve a problem that is getting worse and worse. Copper is used everywhere in the modern world, from water pipes and cables to phones and computers. And while the global push to reduce carbon emissions is based on getting rid of dirty natural resources like oil and coal, an electrified future will need more copper than ever before.\nEven though it is important, the world will likely run out of it in the coming decades. The best mines are getting old, and the few new ones that have been found are either in places that are hard to work in or face years of opposition.\nThe history of commodity markets shows that shortages lead to new discoveries and technologies. The US shale boom in the 2010s turned the oil market on its head, while breakthroughs in nickel processing upended supply forecasts.\nBut it’s getting harder to find new copper deposits because mining has been going on for so long. Copper has been used since at least 8,000 BC in what is now Turkey and Iraq. That means that most of the world’s big deposits have already been found and used. More than half of the world’s 20 biggest copper mines were found more than a century ago.\nBut because copper has been mined for a long time, there are also huge amounts of metal sitting on the ground in waste dumps.\nThe reason for this is a rule that has been around since the beginning of mining: the ore is dug up from the ground, the easiest metal is taken out, and anything that is too hard or expensive to process is thrown away as waste.\nOnly in the last ten years have about 43 million tonnes of copper been mined but never processed. At current prices, that copper is worth more than US$2 trillion (RM9 trillion), so anyone who can figure out how to get it back has a huge chance of making a lot of money.\nReprocessing mine waste when technology gets better or prices go up is not a new idea. But for some types of ore, that hasn’t been possible. And the discovery could be used for a lot more than just waste dumps. There are still millions of tons of waste underground that couldn’t be mined before.\nMuch depends on whether or not mining companies are willing to put Jetti’s plants in their mines. But if the industry fully adopts the technology, the company thinks that up to eight million tonnes of extra copper could be made each year by the 2040s. That’s more than a third of the total amount of copper mined around the world last year.\n“The industry has accumulated this waste material forever,” said Jetti’s founder and chief executive officer Mike Outwin.\n“They’ve been trying to figure it out on their own for about 20 years but haven’t been able to.”\nSo far, only one mine, Pinto Valley in Arizona, has used Jetti’s method. But the results have been so good that three of the biggest copper mining companies in the world, including BHP, have bought shares in the company. The last time it raised money, it was worth US$2.5 billion (RM11.2 billion).", "domain": "mining_engineering"}
