Recovering vanadium values from ammonium bicarbonate solution using heat, sulfuric acid, and ammonium sulfate

摘要

A method of recovering vanadium from an aqueous ammonium bicarbonate solvent strip solution is disclosed. The method includes heating the aqueous ammonium bicarbonate solution at a temperature of from 70 DEG C. to 100 DEG C., followed by addition of sulfuric acid to control the pH in the range of from 6.5 to 8.5 and addition of ammonium sulfate to precipitate out the vanadium.
