Electrowinning
Electrowinning. 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 ...

Innovations: How Hydrometallurgy and the SX/EW Process Made
In the case of the higher energy consumer, the pregnant liquor is pumped five miles from the leach site to the SX/EW plant. The electrowinning of copper requires considerably more electrical energy than does the electrorefining process - an average of about 8 MJ/kg for electrowinning vs about 1.5 MJ/kg for electrorefining.
