Simulation of Anode Corrosion In The Electrowinning

2020-1-30 Abstract: In the electrowinning process of non-ferrous metals, electroplating with insoluble anodes is used. The electrolysis process causes electrochemical wear of the anodes such that they have to be replaced after a certain time. Due to very diverse conditions at different electrolysis plants, the lifetime of those anodes varies from 1 to 7 years.
