The DENR disclosed the highlights of the report of the Technical Review Teams (TRTs) which were commissioned by the Mining Industry Coordinating Council (MICC) to conduct an objective, fact-finding and science-based review of the performance of twenty-six (26) mining companies in the country.
The MICC review covered nineteen (19) nickel mines, three (3) gold and gold and copper mines, three (3) chromite mines and two (2) magnetite/iron mines, for a total of twenty-seven (27) mines of twenty six (26) mining companies. It assessed the mining companies’ practices in terms of the following aspects: legal, technical, environmental, social and economic.
The MICC review categorized mining companies’ practices into:
Minor Corrections 2
Major Reforms 1
Not Acceptable 0
The 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.
In 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.
Among 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.
Four mining companies, also 15% of the total, have technical scores that are lower than 1.5 - Claver, Oriental Synergy, SinoSteel, and Ore Asia.
On 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
The social aspect of the review showed that twelve (12) companies scored below the threshold. These are Benguet Corp. Nickel Mines, Eramen Minerals, Inc., LNL Archipelago Minerals, Inc., Claver Mineral Development Corporation, Carrascal Nickel Corporation, AAMPHIL Natural Resources Exploration and Development Corporation, Wellex Mining Corporation Mine 1, Wellex Mining Corporation Mine 2, Mt. Sinai Mining Exploration and Development, Emir Minerals Corp., Ore Asia Mining and Development Corporation and Strongbuilt Mining Development Corporation.
In 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.
Based 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.
The MICC Report also includes case studies on the Economic Analysis of Specific Options for Selected Mining Companies. They are:
• Benguet Corporation, BC (gold mining) – alternative uses of the inactive Antamok for Benguet Water Supply or Engineered Sanitary Land Fill
• Oriental Vision Mining Philippine Corporation, OVMPC (nickel mining) in Dinagat Island – land use alternatives (agro-forestry)
• Hinatuan Mining Corporation, HMC (nickel mining)– alternative land use to mining in a small island setting
• 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
• Strongbuilt Mining Development Corporation (magnetite/iron) – alternative scale combined with agricultural crop production
The Report generally showed that for the majority of mining companies, improvements in technical and environmental management practices need to continue and scale up.
It 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.
Some 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).
Sec. Cimatu already tasked the MGB to implement the recommendations of the MICC Review Team.


The center is looking at mining reforms, including amendments to the mining act and auction rules, Coal and Mines Secretary Anil Kumar Jain said.
These were progressing well and in the next six to eight weeks, the reforms were likely to get adopted in the statute book, he added.
The statement assumes significance as the mines ministry had earlier sought suggestions from the general public, the mining industry and other stakeholders on proposed reforms in the Mines and Minerals (Development and Regulation) Act, 1957.
“While we are looking at mining reforms, amendments to the MMDR Act, the auction rules, etc., it needs to be mentioned that they are well progressing,” Mr. Jain was quoted as saying in a statement.
He was addressing the ‘CEOs Roundtable on Propelling the Mining Industry Forward through Sustainable Technologies for Atmanirbhar Bharat’, organized by FICCI. The center was trying to introduce a level playing field between PSUs and the private sector, he said. “We are going to open the sector and reduce the requirement of exploration status. The licensing regime of the coal sector where there are milestones that you need to adhere to when in a mine, they have been lacking so far; we have been introducing them.
“There will be a system of incentivising early production. There will be a regime of ‘reward and punish’ in the mining sector, ”he added.
He further said there had been a sea change in the way industries were working over the years and sustainability was the buzzword in the sector currently.

Tungsten Carbide Grinding Balls
Grinding balls are the objects or the media that are specifically used to reduce the particle size of materials for industrial applications. 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.
Tungsten 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.

Humans are more dependent than ever on a metal we’ve been using for 10,000 years. We’re running out of new sources, and breakthrough technologies that have changed the way we use other goods haven’t happened for copper.
Up till now
A 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.
If 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.
Jetti’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.
Large-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.
Sources 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.
This 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.
The 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.
Even 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.
The 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.
But 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.
But because copper has been mined for a long time, there are also huge amounts of metal sitting on the ground in waste dumps.
The 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.
Only 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.
Reprocessing 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.
Much 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.
“The industry has accumulated this waste material forever,” said Jetti’s founder and chief executive officer Mike Outwin.
“They’ve been trying to figure it out on their own for about 20 years but haven’t been able to.”
So 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).
