  • Tantalite Mineral Information and Facts

    Tantalite is found at many of the localities for columbite and also at several other places. A part of the tantalum in tantalite is almost invariably replaced by the closely allied metal niobium, and when the amount of the latter exceeds the former, the mineral is known under the name of columbite.
