Electrowinning is most often used to recover gold and silver from eluates produced by the elution of activated carbon. Some of the practical considerations involved in the design and operation of gold electrowinning cells are described in this chapter, including cell types, bullion removal, and special applications such as electrowinning from gravity concentrates, and sulfide oxidation filtrates.

Oct 20, 2014· Gold bullion is then recovered from the electrolyte by electrowinning. That much is straight forward. However, there are a large number of critical factors which together determine the success (or otherwise!) of gold leaching in a mineral processing plant.
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.
