phosphate rock beneficiation and chemical processing

During the phosphoric acid production by the dihydrate process, the phosphate mineral reacts with a mineral acid, generally sulfuric acid. In this process, more than of 80% of the uranium contained in the raw material passes into the phosphoric acid in the form of U(IV) and U(VI) ions. The separation of uranium from Wet Process Phosphoric Acid
