An Introduction to Copper Electrowinning For Mineral

An Introduction to Copper Electrowinning For Mineral

The electrowinning of copper ions derived from leaching, or solvent extraction is a significant contributor to the global copper commodity supply. The process of electrolysis for copper was first developed in the late 19th century and despite numerous advancements in technology the principles and basic equipment remain the same.
