Gold Refining Electrolysis Process

Electrorefining is a process that uses the principals of electrolysis to recover gold from an alloy typically found in jewelry. Electrolytic gold recovery begins with a bath of hydrochloric acid, which forms the electrolyte. The cathode is usually a thin sheet of 24K gold, but it needs to be better than 99.5 pure.
