Hydrometallurgical Separation of Niobium and Tantalum A

Abstract A mixture of pure Ta 2 O 5 and Nb 2 O 5 was dissolved using two different fluxes, namely NH 4 FHF and Na 2 HPO 4 /NaH 2 PO 4 H 2 O. Selective precipitation and ion exchange were used as separation techniques. Selective precipitation using p-phenylediamine in a fluoride matrix resulted in the isolation of 73(3)% tantalum accompanied by 23(5)% niobium.
