Electrowinning also called electroextraction is the electrodeposition of metals from their ores that have been put in solution or liquefied. 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 economical and straightforward purification of nonferrous metals.

202032Electrowinning is a process used to remove metal ions from liquid solutions such as rinse water plating baths and used process solutions. Most often used to recover precious metals it relies on an electronic current to plate the metal ions onto a cathode.Recovered metals can then be sold for scrap or processed for use in plating.
