Tantalum Processing 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.

What I claim is: 1. A process for the recovery of at least one of the metals tantalum and niobium from an aqueous mineral acid-containing, preferably sulfuric acid-containing, solution containing such metals, by extraction in at least one step by means of an amine, preferably an amine selected from secondary and tertiary, long-chained alkyl amines, in the presence of hydrogen peroxide, and

Recovery of niobium and tantalum by solvent

Leaching. The slag used in this work was obtained after the process of recovery of tin from tailings from Penouta mine deposit. The slag was ground in a ball mill to reach a particle size X < 90 μm. The chemical and physical characterization of the slag has been presented in a previous work. 8 A mineral concentrate obtained by the milling, gravimetric concentration, and magnetic separation of

Selective recovery of niobium and tantalum from low

2016-4-13  Finally, the process was validated in continuous operation at a pilot scale. High recovery yields for Nb and Ta (65%) were obtained as well as high separation factors toward Ti, Fe, P, S, Th and U. The results demonstrate that it is possible to recover and purify Nb and Ta from industrial concentrates without using fluoride solutions.
