  • Columbite-tantalite (COLTAN) >ENGINEERING

    COLTAN (Columbite-Tantalite) is a dull metallic ore found in major quantities in the eastern areas of Congo When refined, COLTAN becomes metallic Tantalum, a heat-resistant powder that can hold a high electrical charge Columbite ((Fe, Mn, Mg)(Nb, Ta) 2 O 6: Iron Manganese Magnesium Niobium Tantalum Oxide) is the most abundant niobium mineral and is used in alloys for improved strength.

    Columbite was long used as a species name but is now split between the iron end-member columbite-(Fe) and the manganese end-member columbite-(Mn) and consequently is the name of an isomorphous series (see Columbite-(Fe)-Columbite-(Mn) Series) The name columbite usually refers to (the more common) columbite-(Fe), formerly known as ferrocolumbite.
