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. Both processes use electroplating on a large scale and are important techniques for the ...

Copper electrowinning is the recovery of copper metal onto the cathode from electrolyte. The electrolyte may be the leach solution or the purified solution from solvent extraction.
