Coltan or tantalite (short for columbite–tantalites) is a valuable mineral.

It is a dull black metallic ore from which the elements niobium and tantalum are got.[1]

Tantalum from coltan is used to make tantalum capacitors which are used for mobile phones, personal computers, automotive electronics, and cameras.[2] Coltan mining[3][4] is widespread in the Democratic Republic of Congo.[5][6][7]
