Niobium

Minerals that contain niobium often also contain tantalum such as columbite ((Fe Mn)(Nb Ta) 2 O 6) and columbite-tantalite (or coltan (Fe Mn)(Ta Nb) 2 O 6) [30] Columbite-tantalite minerals are most usually found as accessory minerals in pegmatite intrusions and in alkaline intrusive rocks
