Coltan (short for columbiteâtantalite 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.Tantalum from coltan is used to manufacture tantalum capacitors, used in electronic products.here has been a significant drop in the production and sale of coltan and niobium from African mines since the dramatic price spike in 2000, based on dot com speculation and multiple ordering. This is confirmed in part by figures from the United States Geological Survey.
