Oct 01, 2014· 1. Introduction. Tantalum and niobium are frequently found together in nature and are simultaneously extracted from a variety of minerals (Roskill Information 10th ed., 2005a).The most abundant Nb and Ta containing mineral is columbite–tantalite (Fe,Mn)(Nb,Ta) 2 O 6. The Nb rich mineral columbite normally contains 5–30% Ta 2 O 5 and 55–78% Nb 2 O 5 while the most abundant Ta …
