A process for purifying and refining gold to 98+% purity is dislosed. The gold to be refined is made the anode in an electrolytic cell with a solution of ammonium chloride as the electrolyte. The purified gold is collected in anode bags and the nongold impurities including silver are dissolved in the electrolyte. The silver is complexed with the ammonium ion in the electrolyte.
