The principal minerals of niobium (Nb) and tantalum (Ta) are columbite and tantalite. This, depending on whether the concentration of niobium or tantalum is greater corresponds to the general formula (Fe,Mn)(Nb,Ta) 2O 6 (Damodaran et al.,1969). Tantalite ore is found primarily in Australia, Canada, Brazil, Southern Africa, Nigeria and
