inorganic chemistryElectrolytic Refining of Silver

Electrolysis or electrolytic refining is a technique used for extraction as well as purification of metals obtained by other refining methods. In the electrolytic refining process, a block or a strip of impure metal is used as the anode, and a thin sheet of pure metal is used as the cathode.

Electrolytic RefiningMining Fundamentals

The electrolytic process is similar to gold, except that the silver anodes are dissolved in a nitric acid bath. The resulting silver will be about 99.9% pure. CopperThe extraction of copper from other ores through electrolysis involves the deposition of copper on the cathode, and using leadcoated anodes.
