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 columbiteÃ¯Â¿Â½??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.
