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)2O6: Iron Manganese Magnesium Niobium Tantalum Oxide) is the most abundant niobium mineral and is used in alloys for improved strength.hen refined, COLTAN becomes metallic Tantalum, a heat-resistant powder that can hold a high electrical charge.
