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.
Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent.
Electrometallurgy is the field concerned with the processes of metal electrodeposition.There are seven categories of these processes: Electrolysis; Electrowinning, the extraction of metal from ores [2]

Pregnant leach solution is used in the solvent extraction and electrowinning (SX/EW) process. [ 1 ] [ 2 ] The portion of an original liquid that remains after other components have been dissolved by a solvent is called raffinate .
Nickel(II) sulfate was produced as a by-product from the electrowinning process. [ 5 ] In 1967 the James Bridge Copper Works were modernised as part of a £3 million redevelopment that aimed to increase outputs of the highest grade electrolytic copper to 50,000 long tons (51,000 t) per year.
