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.

Electrowinning of Gold is a method used to extract gold from its ore. It's a complex and accurate process in which a continuous electric current is applied to the gold bearing ore. The process involves the electrolysis of a …

Results listed in table 3 show that final concentrations of Ag in the electrolyte were lowest at a duty cycle of 10 pct. Gold concentrations were lowest at a 40 pct duty cycle for a 2.0 V pulsed electrowinning test and at a 60 pct duty cycle for a 2.5 V pulsed electrowinning test.
