ABSTRACT:
A process and apparatus for oxidizing vanadium and uranium in wet process phosphoric acid to a higher valence state for extraction by subsequent contact with complex organic extractants. The wet process phosphoric acid is oxidized in an electrolytic cell operated at a controlled potential via use of a reference electrode. The cell comprises a tank having at least one high surface area anode and at least one high surface area cathode separated by an ion exchange membrane.
