How to Purify Gold  Sciencing</h3>TechnologyOperationPreparationIn 1874, Dr. Emil Wohlwill of the Norddeutsche Affinerie in Hamburg, Germany, developed a method to purify gold through electrolysis. The unpurified gold ore is fashioned into a 100 ounce anode, whereas pure gold strips make up the cathode. The electrolyte solution is a mix of gold chloride and hydrochloric acid. When an electric current passes from the anode to the cathode through the electrolyte, the gold at the anode dissolves and collects at the cathode.
