    Electrolytic processes for gold and other precious

    Oct 12, 2017 Both processes use direct electrical current whereby pure metal is deposited at the cathode. Electro-refining is the preferred method as an electrolytic process for gold and other precious metals. The electro-refining process uses a melted solid mixture of impure metal as the anode and a thin sheet of metal as the cathode. When the electrodes are immersed in an electrolyte and an electrical current is applied, pure

    Gold Refining | From Gold Ore to Doré | World Gold

    The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the gold migrates to a negatively charged electrode (cathode), where it is restored to a highly pure metallic state, leaving the impurities as a separate solution or residue
