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.

Over the past 40 years, the copper mining industry has undergone a dramatic shift toward hydrometallurgical extraction of copper at the mine site. This has increased the importance of recovering high-purity copper by electrowinning. High-purity cathode production was achieved by implementing numerous technologies including superior …

Multiple elements can be recovered from e-waste, including base metals such as copper (Cu), precious metals such as gold and silver, and critical metals such as palladium and other REEs (Balde et al., 2017). Among them, Cu has accounted for 10–25% of the metal contents in e-waste, which was higher than the Cu content found in raw and …
