Copper electrowinning: theoretical and practical design

COPPER ELECTROWINNING: THEORETICAL AND PRACTICAL DESIGN 213 Introduction 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 During the electrowinning process, copper ions, which are contained in an EW electrolyte solution, are plated onto stainless steel blank sheets or copper starter sheets When the stainless steel blank sheets are submersed into tanks filled with an electrolyte solution, copper essentially “grows” on the blanks via electrolysis where the cross current creates a solid, 24 inch thick piece of The Electrowinning Process: Part One :: Total 17112020 Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4 The overall reaction is the combination of two electrochemical half reactions The cathodic reaction is: Cu++ + 2e Electrowinning Metallurgist Mineral Processing
