Coltan

Coltan (short for columbite–tantalites 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 the tantalite.
