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. [1]

钶钽铁矿（Coltan），是非洲口语对钶铁矿-钽铁矿这种复合矿物的称呼。 钶钽铁矿是一种含有铌和钽的金属矿。 含有钽的精矿一般指的是“钽铁矿”。

Coltan is short for columbite-tantalite, a dull metallic ore. When refined, coltan becomes a heat resistant powder, metallic tantalum, which has unique properties for storing electrical charge. Coltan occurs in granitic pegmatites, pockets where the deep seated molten rock crystallized last.

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]

Most of the coltan activity takes place in the deep jungle areas along the Southeastern borders of Venezuela or Brazil, causing severe environmental repercussions. Colombia's coltan mines are often located in national parks and on indigenous territory, which forces the native population into the mining industry.
