从硫酸浸出磷盐岩所得的磷酸中同时回收铀和钒。该浸出液同三辛基氧膦和二辛基苯基磷酸的煤油溶液接触,将铀和钒萃取到有机相中。经过
Uranium and vanadium are simultaneously recovered from phosphoric acid obtained from sulfuric acid leaching rock phosphate rock. The leachate is contacted with a kerosene solution of trioctylphosphine oxide and dioctylphenylphosphoric acid to extract uranium and vanadium into the organic phase. after
