Tantalite is purchased and sold solely on its Ta2O5 content. Nb2O5 content is not figured into the payable value for tantalite. If the material contains a minimum amount of 50% Nb2O5 with a small percentage of Ta2O5 it would be traded as columbite. Columbite is purchased and sold on the Nb2O5 + Ta2O5 content, known as Combined Pentoxide (CPO).

preparation of pure oxides of niobium and tantalum from indian columbite and tantalite Journal Article Sarma, B ; Gupta, J Indian J. Tech. A promising solvent extraction procedure, employing cyclohexanone or methyl npropyl ketone, was developed for the preparation of niobium and tantalum oxides of more than % purity from Indian columbite.
· Columbite domains are locally penetrated by tantalite grains (Fig. 5d) and some columbite grains are replaced by patchy tantalite (Fig. 5g). Grains enclosed in fluorite ( Fig. 5 h) show a homogeneous columbite core, which is surrounded by banded tantalite ( Fig. 5 i) or penetrated by tantalite, cassiterite, and xenotime along microcracks ( Fig. 5 i and closeup inset).
Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalumare are extracted. The niobiumdominant mineral in coltan is columbite (after niobium's original American name, columbium), and the tantalumdominant mineral is tantalite.. Columbite has the same composition and crystal .
