The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.
Tantalum is mined at Kenticha mine. It is found in the pegmatitic rocks of the Southern Greenstone Belt. [6] Tantalum is used in making all electronic devices such as mobile phones, cameras, computers and so forth; [1] and its mining programme is the sixth largest in the world. Kenticha mines has resources to the extent of 9,000 tonnes of ...
Coltan is mined in the DRC, mostly in the eastern part of the country in places like the Rubaya mines. Coltan consists of mixtures of the minerals columbite and tantalite in varying proportions, which can be refined into niobium and tantalum, respectively. Cassiterite is a mineral containing tin. It is mined in mines such as Bisie.
It is mined by Ethiopian Minerals, Petroleum and Bio Fuel Corporation, and the products mainly exported to China. [3] Kenticha was mined for tantalum from 1990-2017. [5] Peak production from the mine was 90-95 tons of tantalum concentrate per year, valued at $20 million dollars/year. [3]

[citation needed] Over geological time scales, very few metals can resist natural weathering processes like oxidation, so mainly the less reactive metals such as gold and platinum are found as native metals. The others usually occur as isolated pockets where a natural chemical process reduces a common compound or ore of the metal, leaving the ...
