A liquid-liquid extraction process for making tantalum and niobium boosts production rates 200% over the original process, and increases purity of the refractory metals from 99.7% to more than 99.9%. Key to the method is a series of mixer-settler boxes which operate on the principle of countercurrent extraction. Tantalum and niobium fluorides are fed into the boxes, and are separated from each other on the basis of solubility in methyl isobutyl ketone and aqueous solution at various acid concentrations.
