Mar 21, 2020· Hence, tantalum might even not be considered a CRM in the near future. The stage evaluated for criticality is the extraction, which for EU supply (import reliance ) mainly occurs in Nigeria, a country with a significant "world governance index" (tantalum and tungsten trade are protected by the Conflict Mineral Regulation).
History. Tantalum was discovered in Sweden in 1802 by Anders Ekeberg, in two mineral samples – one from Sweden and the other from Finland. One year earlier, Charles Hatchett had discovered columbium (now niobium), and in 1809 the English chemist William Hyde Wollaston compared its oxide, columbite with a density of 5.918 g/cm 3, to that of tantalum, tantalite with a density of 7.935 g/cm 3.

Mar 02, 2016· Columbite, also called niobite, niobite-tantalite and columbate, is a black mineral group that is an ore of niobium and tantalum. It has a submetallic luster and a high density and is a niobate of iron and manganese, containing tantalate of iron.
Ores. Niobium occurs mostly as an oxide and has a strong geochemical coherence with tantalum. Major minerals of niobium are pyrochlore [(Na, Ca) 2 Nb 2 O 6 F] and columbite [(Fe, Mn)(Nb, Ta) 2 O 6], consisting of niobate, tantalate, iron, and manganese.Pyrochlore occurs usually in carbonatites and in pegmatite derived from alkalic rocks, commonly in association with zirconium, titanium ...
