2014-1-1 · Electrowinning. 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.
