Method of preparing chromium

Disclosed is a method of operating a chromium metal electrolytic cell in series with a chromic acid cell. The feed to the chromium metal cell is the chromic acid-alkali metal dichromate effluent from the chromic acid cell and the product of the chromium metal cell is chromium metal and depleted chro...

description Disclosed is a method of operating a chromium metal electrolytic cell in series with a chromic acid cell. The feed to the chromium metal cell is the chromic acid-alkali metal dichromate effluent from the chromic acid cell and the product of the chromium metal cell is chromium metal and depleted chromic acid-alkali metal dichromate solution. The depleted chromic acid-alkali metal dichromate solution is recycled to the chromic acid cell with make up alkali metal chromate and alkali metal dichromate.
