      The electrolytic process (Wohlwill process) involves dissolving gold from the bullion (anode) in a chloride solution and redepositing the gold on a pure gold or titanium cathode. Silver remains on the anode. The cathodes are melted and cast. In the third process the unrefined bullion is dissolved in aqua regia and silver is precipitated as silver chloride.
