Tantalum Niobium Ore

Tantalum Ore a natural mineral formation containing tantalum in compounds and quantities that make its industrial extraction technically feasible and economically expedient. A distinction is made between tantalum ores proper in which Ta2O5Nb2O5 1 and complex tantalum-niobium ores. The main minerals of tantalum ores are columbite-tantalite
