Electrowinning an overview | ScienceDirect Topics

Electrowinning is the process of “winning” metal from solution using an applied voltage. Gold electrowinning is usually performed in relatively small vessels or cells that are about 1 m long and contain less than 1 m 3 of solution. These cells often contain several cathodes and anodes, although there is one extra anode. The cathodes commonly consist of steel wool (30 kg m − 3)

Electrowinning and Smelting Resource Book

Electrowinning Theory Gold is recovered from pregnant (gold bearing) solution by the process of electrowinning. An electric current is passed through the solution causing solid gold to plate out on steel wool cathodes. Electrowinning is performed in cells, constructed of non-conducting plastic material. The cell contains a set of cathodes (negative electrodes) and anodes (positive
