Separation of niobium and tantalum using continuous

Niobium and tantalum are valued for their uses in nuclear, steel, aviation and electronics industries. This paper elucidates the development of a multistage counter-current separation process for obtaining pure niobium and tantalum from the hydrofluoric acid solution of Coumbite-Tantalite ore (leach liquor), with trioctyl amine (TOA) as the extractant solvent.

About tantalum TIC

Generally, the tantalum values in solution are converted into potassium tantalum fluoride (K 2 TaF 7) or tantalum oxide (Ta 2 O 5). The niobium is recovered as niobium oxide (Nb 2 O 5 ) via neutralization of the niobium fluoride complex with ammonia to form the hydroxide, followed by calcination to the oxide.

A study has been carried out on Ta and Nb recovery by a liquid-liquid extraction process using 4-methylacetophenone (4-MAcPh) as the organic phase. The 4-MAcPh was compared to methyl isobutyl ketone (MIBK) with respect to extraction efficiencies (D values) at different concentrations of H2SO4 in the aqueous phase. The results showed a similar extraction of Nb for both solvents.
