Electrolytic refining of copper was first patented in England by James Elkington in 1865 and the first electrolytic copper refinery was built in Newark, New Jersey, in 1883. There were teething problems with the new technology. For example, the early refineries had trouble producing firm deposits on the cathodes. As a result, there was much secrecy between refinery operators as each strove to

A strip of thin silver was then placed in boric acid, which was heated to redness very slight action took place when oxide of silver was substituted the oxide dissolved up and formed an opalescent mass, which was soluble in water, but from which a small quantity of black powder separated. The experiment was repeated with phosphoric acid. At a dull red heat the silver was attacked, and

c Electrolytic Refining In this method the impure metal is made to act as anode. A strip of the same metal in pure form is used as cathode. They are put in a suitable electrolytic bath containing soluble salt of the same metal.
In electrolytic refining, a strip of impure metal is used as the anode, a pure metal strip as the cathode and a solution of the metal as the electrolyte. The impurities gather at the anode and the pure metal at the cathode. When a heated roller is passed over an impure metal rod, the impurities shift with the roller toward the right and pure metal crystallises on the left side. This technique
