Unlike many other metals, tantalum and niobium are sourced from two main ores: tantalite in the case of tantalum, and pyrochlore for niobium. Both are associated with igneous intrusive rocks, although tantalite is found in pegmatites, while the world's pyrochlore deposits occur in alkaline intrusives – carbonatites.

2006) and among the seven African countries hosting tantalite resources (L. Mlambo & M. Mugoni 2011). • In 1943 the Government Tantalite Scheme failed to produce tantalite at a profit and in the minerals priority list of the same year, tantalite production on the known claims was considered uneconomic (NAZ documents).
Tantalite Mining Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.
Mining contributes to about 1.5% of Rwanda's $7.8bn GDP, and the country has recently signed a five-year mining contract worth $39m with a unit of Oman's Mawarid Mining to extract tantalum, tin and niobium. The country now has a good reputation for mining and the Rwandan people see their mines as an asset.

MINING AND PROCESSING : Tantalum is obtained through the processing and refining of its ore, tantalite, which is the mineral containing tantalum. Tantalum mines mostly operate as open pits, although some are underground. The mining process includes blasting, crushing, and transporting the tantalite ore to commence the separation of tantalum.
Prominent examples of this are the Liberian-American-Swedish Mining Company (LAMCO) (from Sweden and America) and the German-Italian mining company Bong Mining Company, BMC, which have been mining iron ore since the 1950s. ... often for preconcentration. As tantalite has a density, depending on mineralization, between 6.6 and 8.0 g/cm³ and is ...
The recovery of tantalite in Nigeria dates back to the 1940's as a by-product of cassiterite mining [2, 3]. Later, large tonnages of granite containing about 0.26% Nb2O5 in urania pyrochlore (3.1% U3O8, 3.3% ThO2, 37.5% Nb2O5 and 3.5% Ta2O5) were
