Abstract
Uranium and vanadium values are recovered from acid solutions by reducing the dissolved uranium and vanadium to the tetra and trivalent state respectively electrolytically or preferably with zinc, aluminium or iron, and adding phosphate ions to the reduced solution at a pH of 1 to 1.5 thereby precipitating the uranium as phosphate. The latter is separated and further phosphate ions are then added and the pH adjusted to 2.5 to 3.1 thereby precipitating vanadium phosphate. The invention is particularly applicable to the recovery of uranium and residual vanadium from the water-insoluble residues left after leaching salt roasted carnotite or roseoelite to dissolve out sodium vanadates. Such insoluble residues are dissolved in acid and treated according to this invention. The initial acid leach solution may be acidified with hydrochloric acid for example to a pH less than 1 and reduction effected with zinc, aluminium or iron, preferably at 50 to 90 DEG C. Phosphate ions are added to the reduced solution in the form of phosphoric acid pyrophosphoric acid or alkali metal salts thereof and the pH is preferably adjusted with ammonia gas. Uranium precipitation is preferably effected at 50 to 90 DEG C. and the uranium phosphate precipitate may be converted to uranium dioxide by fusion with alkali metal hydroxides or carbonate. The solution remaining after the vanadium has precipitated is treated with phosphate ions, generally between 1 and 8 times the molar concentration of vanadium, and the vanadium precipitated by adjusting the pH to 2.5 to 3.1. Vanadium phosphate precipitate may be roasted at 350 to 650 DEG C. and if desired salt may be added to the roast and the vanadium leached from the roasted material with water. Alternatively the vanadium phosphate may be recycled to the original salt roast of the ore.
