Tantalite contains some niobium, with the mineral being referred to as niobite or columbite when the niobium content is greater than that of tantalum. Indeed, until the discovery of the world's pyrochlore deposits in the 1950s, niobium was a by-product of tantalum mining, with increasing demand ensuring that it was highly valued and highly ...

 · occurs mainly in the albitized zones of granite pegmatites, often associated with tantalite or columbite. Struverite, which is a titanium-bearing oxide, is a low-grade source of tantalum that is recovered from tin-mining wastes in South-east Asia. Struverite typically contains about 12% each of tantalum and columbium oxides [2].

The single largest operating tantalum mine is the Mibra operation of Companhia Industrial Fluminense in Nazareno.This mine has the capacity to produce 220 tonnes Ta 2 0 5 per year which equates to approximately 15% of current global primary production,although the latter are at historically relatively low levels. At 2007-2008 levels the Mibra ...
