We are specializing in columbite and tantalite, which are the critical elements used in cell phones, aerospace
industry, defense, medical industry, and other high technology applications.
About Coltan (short for columbite–tantalite) is a dull black metallic ore from which the elements niobium 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, necessary for modern electronic products. It
is also used in high-temperature alloys for air and land-based turbines and other components used in defense
and aeronautical industries.
