Copper Electrowinning - 911metallurgist.com

The very survival of the U.S. copper industry is presently tied to the leach SX-EW process, a technology which 15-20 years ago was considered too radical and far fetched to be accepted by the industry. It came to life rather dramatically with the Ranchers Bluebird Mine and shortly thereafter with the Cyprus Bagdad plant. All of a sudden, it was a viable technology and as we have seen has ...

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.

Copper Electrowinning. Typical of electrowinning from aqueous solutions is copper electrowinning. The electrolyte entering the cells contains 25–60 g l-1 of copper, 50–180 g l-1 of sulfuric acid, and 5–10 g l-1 of iron salts (Habashi, 1998). It is produced by leaching of copper ores, with solution purification by solvent extraction.
