Economic Geology of Niobium and Tantalum

Industrial recovery methods underline the inertness of tantalum and niobium: ore is fused with alkalis and dissolved in concentrated fluoric acid followed by liquid-liquid separation of the resulting complex Ta-Nb fluoride salt solutions. Fluorine alone has little effect on Ta and Nb solubility in granitic melt (Fiege et al. 2011).
