ABSTRACT:
A process for recovery of chromium in an aqueous solution comprising converting the chromium to chromyl chloride, separating the chromyl chloride from the aqueous solution, either as a heavy underlayer, or by extraction into a solvent, purifying the chromyl chloride, hydrolyzing the purified chromyl chloride to form a solution, and drying or precipitating the solution to form chromium, either as chromic acid or a chromate salt.
