What is Electrowinning? - wiseGEEK

Electrowinning 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.
