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 niobiumdominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalumdominant mineral is tantalite.

The chief tantalum ores are tantalite, which also contains iron, manganese and niobium, and samarskite, which contains seven metals. Another ore which contains tantalum and niobium is pyrochlore. The main mining areas are Thailandia, Australia, Congo, Brazil, Portigal and Canada.

In 2000, Australia produced around 45% of the world's tantalum concentrates (tantalumcontaining minerals), but by 2014 this dropped to just 4%. The substantial decrease was a result of high extraction and an unfavourable exchange rate, which meant that mining the ore was no longer viable in Australia.
