Columbite-tantalite - Wikipedia
La columbite-tantalite, (detta anche Coltan) è una miscela complessa di columbite (Fe, Mn)Nb 2 O 6 e tantalite (Fe, Mn)Ta 2 O 6, due minerali della classe degli ossidi che si trovano molto raramente come termini puri.. Il termine "coltan" è usato colloquialmente in Africa per riferirsi ad una columbite-tantalite a relativamente alto tenore di tantalio.La miscela estratta in diversi paesi ...

Tantalite Buyers - TanCo Minerals Brazil
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).

Columbite has the same composition and crystal symmetry (orthorombic) as tantalite. In fact, the two are often grouped together as a semi-singular mineral series called columbite-tantalite or coltan in many mineral guides. However, tantalite has a much greater specific gravity than columbite, more than 8.0 compared to columbite's 5.2.
