coltan 66

Coltan (short for columbite–tantalite and known industrially as tantalite) is a dull black metallic ore from which the elements niobium (formerly "columbium") and tantalum are extracted. The niobium-dominant mineral in coltan is columbite, and the tantalum-dominant mineral is tantalite.  Tantalum from coltan is used to manufacture tantalum capacitors, used in electronic products. Coltan mining has been found most in Columbia and the Democratic Republic of Congo.

The more ore containing niobium and tantalum least, is called columbite-tantalite or Ferrocolumbita-tantalite, and the less tantalum niobium and tantalite-called Columbite. On both, columbite and tantalite, together with tantalum-bearing minerals and niobium were informally known by the abbreviation "coltan".

Tantalum and niobium are refractory metals, ie having a high melting point and withstand exceptionally high temperatures, 3017 ° C and 2468 ° C respectively. The heat resistance of Ta is two times that of the iron and is only exceeded by the tungsten and rhenium, and consequently, the Ta and Nb have the potential to be used in high temperature resistant applications. Even tantalum carbide (TaC) 3880 ° C and supports also has a hardness similar to diamond.
