Tantalum ORE Coltan: Columbite - Tantalite

Product Description

Tantalum Ta2O5 ORE Coltan (short for columbitetantalite and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name, columbium), and the tantalum-dominant mineral is tantalite.



When refined, COLTAN becomes metallic Tantalum, a heat-resistant powder that can hold a high electrical charge. Columbite ((Fe, Mn, Mg)(Nb, Ta)2O6 : Iron Manganese Magnesium Niobium Tantalum Oxide) is the most abundant niobium mineral and is used in alloys for improved strength.



Coltan is used primarily for the production of tantalum capacitors, used in many electronic devices. Many sources mention coltan's importance in the production of mobile phones, but this is an over-simplification, as tantalum capacitors are used in almost every kind of electronic device.
