A procedure has been developed for simultaneous recovery of uranium and vanadium from sulfuric acid leach solutions of salt roast calcines. A combination of alkylamines and organophosphates in a kerosene solution will selectively extract uranium and vanadium from sulfate solutions grossly contaminated by chlorides, aluminum, and ferric iron. The mixed extractants give better results than amines or organophosphates when used independently. The loaded amone-organophosphate can be stripped with sodium carbonate to give a concentrated solution of the uranium and vanium suitable for processing by conventional procedures to separately recover the uranium and vanadium. Alternaively, thehe loaded organic can be stripped with sodium hydroxide to give a sodium diuranate product and a solution of sodium vanadate. The paper presents results of batch and continous tests on typical salt roast leach solu-tions to investigate the factors influencing separation and recovery of specification- grade uranium and vanadium products.
