Electrowinning Cell Process - Eaglerock Machinery
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.

Gold electrowinning and amperage problems - Pyrometallurgy
Some friends are operating a small carbon elution plant. Their gold electrowinning processes 300kg of carbon per month. They have low-pressure boilers and usually leave the carbons in for 48 hours per elute. They test the pH strength every morning and every evening and it usually reads between 12.5 to 13.

Electrowinning Cell – for safe and easy metals recovery
Installations normally operate in the buss bar range of 2.1–5 volts and 60–90 amps per cathode and some high-grade solutions will use higher amperage per cathode. Any fumes generated during electrowinning are removed via the local electrowinning cell exhaust system.
