Electrowinning cell. Electrowinning is a process used to recover metals (eg. gold and silver) from concentrated solutions by applying a voltage across electrodes immersed in a concentrated solution. The positive terminal from the rectifier is connected to the anode where the oxidation reactions occur and electrons are generated.

A relatively high concentration of metal in solution also is needed for conventional electrowinning processes to operate efficiently. Electrowinning can recover 90 to 95% of the available metals, but it is known to operate efficiently only at high metal concentrations. This is especially true when flat plate cathodes are used.
