How to Purify Gold Sciencing

How to Purify Gold Sciencing

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.
