called electrowinning. SX-EW capacity in the U.S. was 358,000 megagrams (395,000 tons) in 1989. The SX-EW process is an alternative to smelting, but it and its emission streams are fundamentally different from smelting, and as such it will not be addressed in detail in this document.

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 ...
