ABSTRACT:
A process of separately recovering vanadium and molybdenum from an aqueous solution containing a vanadium compound is disclosed. The process comprises adjusting the pH of such a solution to a pH between 1.5 and 7, contacting the solution with a weakly basic anion exchanger in the salt form, eluting said anion exchanger with an ammonium hydroxide solution having a strength between about 1 and 4N, crystallizing the resulting ammonium vanadate, and separating the same from the vanadium and molybdenum solution obtained in said elution.
