How do you separate other metals, like copper, from pure

Apr 11, 2007Best Answer Silver is separated from copper by a metallurgical process called electrorefining. Melt the silver-copper metal into an anode and electrolize it with a stainless steel cathode with a DC current source 40 to 50 Amps per square foot (about 2.5 volts) in a solution of coppersilvernitric acid.
