Question

Want to study about electrorefining.

Can anyone explain it ?​

Answer 1

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal.

Answer 2

Electrorefining is a process in which materials, usually metals, are purified by means of an electrolytic cell. ... An electric current is passed between a sample of the impure metal and a cathode when both are immersed in a solution containing cations of the metal.
