A mineral deposit is a place in Earth's crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse is not true.

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).
