Metal Recovery Processes | SpringerLink
Electrowinning is the electrolytic process of "winning" or recovering dissolved metal using an applied potential. An example of an electrowon copper plate is shown in Fig. 7.1. This process is practiced extensively in the metals industry. Copper, zinc, and gold, as well as other metals are produced by this process.
