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.
