Coltan
Coltan or tantalite (short for columbite–tantalites) is a valuable ore. It can be made into the elements niobium and titanium.[1] Coltan is a mixture of two minerals, columbite and tantalite.
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]
