Tantalum ore

Description:

A natural mineral containing tantalum in economically significant quantities.

Main view:

Coltan (contains columbite-tantalite), a major source of tantalum.

Application:

Mining and processing to produce tantalum used in the manufacture of capacitors for electronics, medical implants, heat-resistant alloys and corrosion-resistant tools.

Mining:

The main producing countries are the Democratic Republic of Congo, Rwanda, Brazil, Australia.

Tantalum ore is an important resource for tantalum needed in high-tech and medical applications due to its excellent electrical, thermal and corrosion resistant properties.
