Comments if any:

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 tantalite.

Tantalum from coltan is used to manufacture tantalum capacitors which are used for mobile phones, personal computers, automotive electronics, and cameras.

Coltan mining is widespread in the Democratic Republic of Congo.
