Design Copper Electrowinning Circuit

2017-2-23  Copper electrowinning is based on the copper electrolysis principle which uses the electrical power to reduce copper ions in solution to copper metal on the cathode and to oxidize water on the anode in oxygen gas and hydrogen ions. The chemical equation (a) gives the copper electrolysis global chemical reaction. 2H2 O + 2CuSO4

Copper electrowinning: theoretical and practical design

2009-10-15  The electrowinning of copper ions derived from leaching, or solvent extraction is a significantcontributor to the global copper commodity supply. The process of electrolysis for copper wasfirst developed in the late 19th century and despite numerous advancements in technology theprinciples and basic equipment remain the same. The first part of this paper deals with thetheoretical requirements and fundamental equations and principles that govern copperelectrowinning. The second part discusses the practical requirements for designing a copperelectrowinning

Improving base metal electrowinning

2020-10-13  In copper electrowinning, the effects of temperature, power outages and concentrations of cobalt and manganese on anode corrosion and current efficiency have not been well investigated. Benchscale tests were used to investigate these effects. Anode corrosion in all experiments was minimal probably due to the presence of at least 150 mg/L
