Cassiterite: The tin mineral cassiterite information and pictures USES Cassiterite is an economically important mineral, being the primary ore of the metal tin. It is also used as a collectors mineral with the transparent forms being highly desired. Cassiterite is occasionally used as a minor gemstone, being faceted mostly for collectors. NOTEWORTHY LOCALITIES Bolivia produces some of the finest Cassiterite specimens in abundance. Bolivian locations where lustrous and sometimes transparent crystals come from include Viloco (Araca), Loayza Province; Huanuni, Dalence Province, Oruro Department; and Llallagua, Potosi Department. Some of the Brazilian gem pegmatite in Minas Gerais have produced good specimens, especially Linópolis, in the Doce valley. China has also become an important producer of Cassisterite, with outstanding shiny black crystals originating in several localities including Mt.

Xuebaoding, Pingwu, Sichuan Province; the Yaogangxian Mine, Hunan Province; and Dayu, Jiangxi Province. Transparent brown crystals come from Ximeng, Yunnan Province, China. In Russia, excellent lustrous crystals come from Merekski, Khabarovskiy Kraj. In Europe, one of the most classic localities of Cassiterite is Krásno and Horní Slavkov (Schlaggenwald), Bohemia, Czech Republic. Also in Bohemia is Krupka, Krušné Hory; and similar crystals are found in a similar geological deposit across the German border at Ehrenfriedersdorf, Erzgebirge, in Saxony. Cornwall, England, has produced classic specimens in several deposits; especially noteworthy are the Redruth-St. Day and St. Agnes Districts. Other important European localities include La Villeder, Le Roc Saint-André, France; Panasqueira, Portugal; and Penouta, Spain. In Australia, transparent brown crystals come from the Aberfoyle Mine, Rossarden, Tasmania; and fairly large crystals from Elsmore, New South Wales.

Cassiterite is not common in the U.S. Some of the gem pegmatite deposits, especially those in southern California and New England have produced sporadic Cassiterite. Some specific good localities include Greenwood, Oxford Co., Maine; Amelia, Amelia Co., Virginia; and Taylor Creek, Sierra Co., New Mexico. In Mexico, noteworthy reniform and botryoidal " Wood Tin " come from an unspecified locality in Durango. Cassiterite Meaning, Powers and History Cassiterite Meaning, Powers and History Learn all about your birth symbols Your Birthday: Cassiterite is a major ore of tin. In fact, it is the chief ore of tin and was one of the first metal alloys. Cassiterite’s name actually derives from the Greek word for tin, kassiteros. The name has also been said to come from the Phoenician word Cassiterid, referring to the islands of Ireland and Britain, both ancient sources of tin. Cassiterite’s importance as a tin ore has been known for millennia. Since 2000 BD, cassiterite mines have been worked. One of the oldest cassiterite mines is in Cornwall, England and is now completely exhausted of all minerals.

Cassiterite was actually Britain’s most important export. In fact, the Roman invasion of Britain was mostly caused by the Roman’s desire to control Britain’s cassiterite exports. During the Bronze Age, cassiterite was a major discovery used towards technological advancement, as it was used to form the alloy bronze. This was done by heating up cassiterite and adding it to molten copper.

Combine Garnet with: Garnet Pendants Cassiterite is used as a source of tin and bronze, but is also valued as a beautiful gemstone. Rating a 6 to 7 on the hardness scale and having perfect cleavage and high density, cassiterite is very easy to cut. However, the stone needs a good polishing to become a beautiful gemstone suitable for faceting in jewelry. Cassiterite is usually found in small stones. Large cut stones of more than one carat are rare. Cassiterite is highly prized for its beautiful sparkle, which comes from its high adamantine luster. Its luster can also be sub-metallic and greasy.

Cassiterite is usually an opaque stone, but can also be transparent and translucent when the crystals are thin. It is usually black, but can also be reddish brown, brown, brownish white, yellow, red, or colorless. Crystals may also have white or brownish streaks. Crystal twinning is common within the stone. Cassiterite is usually found in or near granite masses, igneous rocks, or alluvial deposits. When it is found as rounded alluvial pebbles, cassiterite is called stream tin. It is usually found in association with fluorite , apatite , wolframite , arsenopyrite, bismuthinite, topaz , quartz , tourmaline , mica, and molybdenite . The stone is usually found as an eight sided prism which consisting of two four-sided prisms, one of which is dominant. The most highly prized cassiterite comes from Erongo, in central Namibia, and Galicia, in Spain. High quality specimens have also been found in hydrothermal veins in the tin mines of Bolivia .

Cassiterite can also be found in various locations around China , Indonesia, Malaysia, Mexico , Namibia, Russia , Thailand , and Spain. Cassiterite is a stone for those who desire greatness and perfection. It can aid the wearer in getting rid of hesitation, wasted energy and time, and regression, pushing the wearer towards growth. It has also been said to be extremely helpful for those who suffer from addiction. January Did you know that garnet is one of the oldest gemstones in human history, dating back to the Bronze age?

Cassiterite (image - Ralph Bottrill via Wikimedia) Cassiterite can take several forms, including massive (an irregular mass of indistinguishable crystals), botryoidal (rounded "blobs"), reniform (kidney-shaped), or prismatic (crystal columns). Cassiterite crystals are typically opaque, brown to black, shiny and metallic-looking - and these can be appealing to mineral collectors. However, cassiterite crystals are sometimes found in the form of at least partially translucent / transparent crystals - and as can be seen in the second image, these are on occasion fashioned into cut gems. [1] Cassiterite has a hardness of 6-7 on the Mohs scale [1] and crystallizes in the "Tetragonal - Ditetragonal Dipyramidal" crystal system. [2] It can be found in association with tourmaline , topaz , fluorite , apatite , quartz , muscovite , wolframite, molybdenite and others.

[1] The chief source of cassiterite nowadays is Bolivia - but the mineral is also found in many places around the world - including Ecuador, Brazil, Thailand, Malaysia, Indonesia, Russia, Australia, The USA, Canada, China, and the Congo (where it is considered a "conflict mineral" due to fighting for control over cassiterite resources in the Walikale territory.) [3] Cassiterite used by industry goes towards the manufacture of tin which is used as an ingredient in solder used by the electronics industry. There have, sadly, been reports of cassiterite sourced through child slave labor reaching the world's industrial supply chain. This issue appears highly complex - mines in the Congo may be in war zones and lack adequate governmental control to prevent human rights abuses. [4] Cassiterite - History Tin has been in use since ancient times. Utensils made from brass (a tin-copper alloy) date from around 3,500 BC. Pliny referred in 49 AD. to the existence of tin-lead alloys, which we now know as solder. In ancient times, tin was mined in England and Spain.[5] It was one of the seven noble metals and was attributed to Jupiter.

Cassiterite gained its name in an interesting and unusual way. It was named after the "Cassiterides", which were said to be islands "off the western coast of Europe". The Cassiterides were discussed by Herodotus in his History - and he believes their identity to be the British Isles, though he admits to being somewhat uncertain as to their identity. [6] Some have speculated that they were the Scilly Isles - but the exact location of these islands has never been found and it is currently believed that their existence may have been an invention of Phoenician traders who wished to exert control over the tin trade by keeping the source of their supply secret. The existence of the Cassiterides may have been a total fabrication to preserve the secrecy of the location of the tin mines in England: Cassiterite was once mined in Cornwall, England and in ancient times the old Cornish tin mines were an important source of the ore - prior to their being exhausted.

[7] [8] Cassiterite has certainly been known about since ancient times - however the earliest mention of the word I can find in literature is in François Sulpice Beudant's 1832 Traité élémentaire de minéralogie (Volume 2 p.618). Knowing that the mineral has been in use since ancient times, it must previously have been known by different names - and in William Phillips and Robert Allan's 1837 An Elementary Introduction to Mineralogy (p.250) we find a list of these names - Zinnstein (German), Etain Oxide (French), Tinstone, Pyramidal Tin Ore, Stannolite (English). Peering back further into the arcane vaults, we find in Nehemiah Grew's 1681 Musaeum Regalis Societatis (p.328) that the mineral was at that time simply called tin ore or tin-stone. The name stannolite does not appear to have been ancient - however it derives from the old latin name for tin - Stannum. Cassiterite Gemstone (From Bolivia.

Afghanistan,Malaysia : LUSTER seals JV agreement with VENTURIAN MINERALS In 2012, the total output of refined tin declined a little, which was mainly related to the following condition that the production enthusiasm of metallurgy enterprises was shocked because the downstream demand shrank and the cost of tin ore remained high. Photos of Natural Tin Ore, Tin minerals and specimens TIN ORE Tin is said to have been found native, but, if so, is of very rare occurrence. It is chiefly found in the form of the oxide, cassiterite (tinstone), which may be regarded as the sole important source of the metal. The mineral stannite, a sulfide of copper, iron, and tin, is of little significance as an ore mineral.

Tin is a bright, white metal, malleable and ductile. It has a specific gravity of 7-3, and melts at 232 C. A bar of the metal, when bent, emits a crackling sound. The chief use of tin is in the coating or manufacture of tin-plate (sheet-iron with a very thin coating of tin) and the tin plate thus formed is used in roofing. Tin is use din alloys such as pewter, tinfoil, solder, and antifriction metals, and bronze and bell metals, as a part of pewter in various utensils, etc. An amalgam of tin and mercury is used in "silvering" mirrors. The artificial oxide of tin is used as a polishing powder. Stannic chloride is employed as a mordant in dyeing. Cassiterite is obtained from both lodes and alluvial (placer) deposits. In the former it may be associated with arsenic, copper ore and iron pyrite , wolframite, etc., and in alluvial deposits it is often associated with ilmenite or titaniferous iron, monazite , zircon , topaz , tourmaline , etc.

Cassiterite is a mineral which, while occurring in small quantities in many localities, is found only in a comparatively few commercial deposits. The proportion of tin in ores is usually expressed in pounds of black tin (tinstone containing about 70 per cent, metal) per ton. In the case of alluvial deposits, less than 2 pounds per ton has been profitably worked. The alluvial or mine stuff is concentrated, up to as near 70 per cent, of metallic tin as is practicable, by means of shaking tables and other mechanical contrivances, and when associated with ilmenite, wolframite, or other magnetic minerals, by electro-magnetic separators. The dressed product or "concentrate" is smelted in reverberatory furnaces, and the metal further purified up from 99.2 to 99.9 per cent. Salts of tin have uses in the pottery and enameled iron industries and as a mordant in calico printing. Cassiterite is found sparingly distributed in some igneous rocks and is a constituent of some pegmatites and of a few contact metamorphic deposits.

Cassiterite occurs in pneumatolytic veins, associated with acid rocks, granites , as in Cornwall. It occurs also in many veins, nearly all of which are of deep-seated origin. The main occurrence of cassiterite is in quartz veins, associated with fluorite , topaz, tourmaline, axinite, and apatite , as in Cornwall, Saxony, and Bolivia. Stannite is found in many deposits in Bolivia, particularly at Potosi. Both stannite and cassiterite are almost insoluble in ground water; consequently tin deposits are enriched near the surface when other minerals are removed by solution. Minor veins of cassiterite are sometimes found in rhyolite flows, in which they were evidently formed shortly after the consolidation of the rock. We have here then high temperature deposits originating near the surface. It may be recalled that topaz is sometimes found in lithophysse in rhyolite and these phenomena indicate a retention by the lavas of certain of their volatile constituents until consolidation of the rock. Such deposits contain concretionary cassiterite and "wood tin" associated with hematite , chalcedony, and opal, sometimes also with wolframite and bismuth minerals.

Occurrences of this kind have been described from Mexico and from Nevada. Cassiterite is extremely resistant to weathering, as shown, for example, by its occurrence in placers. It is held by some authors that the so-called fibrous tin ore or "wood tin" which is often found in placers is a product of alteration of cassiterite, but the question does not seem to be definitely settled. If secondary, it is probably derived from stannite. Much tin is obtained from placers, and fully one half of the world's supply of tin is obtained from placer deposits, resulting from the degradation of tin veins. Localities of alluvial tin deposits are Malay States; the islands of Banka and Billeton, in Indonesia; Cornwall; Mount Bischoff, in Tasmania, etc. Of the total world's production of tin ore, about 80 percent is contributed by the Malasia, Thailand, Bolivia, and Indonesia. The remainder is produced chiefly in England, Australia, Congo, Russia, and Somalia. The chief primary vein sources of tin are and the lode deposits of Bolivia, Congo and Cornwall.

The Malaysian ore is obtained chiefly from alluvial deposits that have been derived from the disintegration of the older rocks of the Peninsula. These rocks consist of slates, schists and crystalline limestones , into which granites are intrusive. The tin ores were introduced with the granite intrusion and were deposited for the most part in the surrounding sedimentary rocks. The region is notable as furnishing an example of the deposition of tin ore in crystalline limestone, this feature being well exemplified in the crystalline limestone of the Kinta district in Perak. The primary veins in the limestone have a matrix of calcite . The veins are in some places very rich in cassiterite, with little or no other associated minerals; but as a rule pyrite, chalcopyrite , arsenopyrite , and fluorite are found in the veins. An interesting feature is provided by the occurrence of primary pipes of tin ore in the limestone. The ore of these pipes, like that of the veins, consists of cassiterite and sulphides in a matrix of calcite. Another interesting feature of the limestone deposits is the occurrence of secondary pipes infilled by the weathering residues of the limestone.

The presence of cassiterite makes these pipe infillings valuable as tin ore. Tin ore also occurs in the form of disseminations, veins, and pockets in the granite, associated with quartz, tourmaline, and topaz. At one locality a pipe of tin ore in granite has been worked. This pipe resembles those occurring in the Waterberg tinfield of the Transvaal. Most of the Malaysian tin-ore has, however, been obtained from the alluvial or detrital deposits that have been derived from the disintegration of the vein formations by weathering and denudation. These deposits occur superficially for the most part and are easily worked. The minerals commonly found associated with cassiterite in the alluvial deposits include ilmenite, arsenopyrite, wolframite, monazite, topaz, and tourmaline. Placer tin deposits of Asia: The granitic ridge which forms the backbone of the Malasian Mountains stretches southwards into the islands of Banka and Billiton in Indonesia, and northward into Myanmar (Burma), Thailand and the province of Yunnan in China; and in all these areas the granitic intrusions are associated with deposits of tin ore.

Indonesia has contributed large supplies of tin ore. Here the origin and mode of occurrence of the alluvial deposits are much the same as in the Malasia. The tins bearing alluvium forms a bed about 3 feet thick lying on the granites and slates, and is covered by a layer of clayey and sandy overburden, the thickness of which averages about 30 feet. In Myanmar and Thailand also the mining has been largely alluvial. In Myanmar, the chief districts are those of Mergui and Tavoy, where granites are intrusive in slates and quartzite . The tin ore (cassiterite) is found as a constituent of stringers, veins, and pegmatites, associated with granitic intrusions; but it occurs also in the surface alluvium derived from these. The cassiterite is associated with wolframite. In China, tin ore is found abundantly in the province of Yunnan, notably in the Mengtze district, where cassiterite is associated with pyrite and chalcopyrite in limestones that are supposed to be of Permian to Triassic age.

Granite intrusions have penetrated these limestones, which contain veins and pipes of tin ore. In the weathering zone the limestone is traversed by fissures, and the red clay filling these fissures and other cavities contains cassiterite. The conditions of occurrence in Yunnan thus recall those met with in various parts of the Kinta limestone deposits of Perak. Tests: Heated on charcoal with sodium carbonate and charcoal, tin compounds are reduced to the metal, which is soft and malleable. The encrustation given by heating tin compounds alone on charcoal, when moistened with cobalt nitrate and strongly reheated, is a blue-green color. The United States at present produces only a small amount of tin ore as the tin deposits of the United States are consistently small. In the Carolina tin belt, that extends from Gaffney, S. C., nearly to Lincolntown, N. C., cassiterite occurs in pegmatite, which is characterized by abundant muscovite, quartz, and a little plagioclase feldspar.

At Silver Hill, about 8 miles southeast of Spokane, Wash., and at the Etta mine, South Dakota, cassiterite is found in pegmatite dikes. Tin veins are also found in the Franklin Mountains, Texas, about 12 miles north of El Paso. In the Temescal tin district, in western Riverside County, California, the tin deposits are veins in granite. The district has produced some tin, but the mine is now closed. The vein matter is dark tourmaline, high in iron and quartz, with which cassiterite is associated. Arsenopyrite and copper minerals are reported. The tin oxide is distributed either through the vein matter or in stringers and bunches. The average of the ore milled contained about 5 per cent of the oxide. On Lost River, Seward Peninsula, Alaska, where granite intrudes limestone, a contact metamorphic zone is developed, in which some cassiterite is found. Cassiterite is also found in this region in granite and in quartz veins. Historically, most of the production of US domestic tin ores in the United States comes mainly from Alaska.
