Buyers of Tantalite (coltan) ore / concentrate

Tantalite is purchased and sold solely on it's 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-tantalite (COLTAN) > ENGINEERING

COLTAN (Columbite-Tantalite) is a dull metallic ore found in major quantities in the eastern areas of Congo. When refined, COLTAN becomes metallic Tantalum, a heat-resistant powder that can hold a high electrical charge. Columbite ((Fe, Mn, Mg)(Nb, Ta) 2 O 6 Iron Manganese Magnesium Niobium Tantalum Oxide) is the most abundant niobium mineral and is used in alloys for improved strength.
