electrorefining gold from ore

Electrolytic Refining of Gold

By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution. The active agent in causing the solution of the gold is chlorine; this transforms the silver in the anode to chloride, and the presence of silver chloride tends to prevent the solution of the gold by forming a protective coating on the bars.
