The gold can then be removed from the solution by electrowinning onto steel wool hodes (refer 'Electrowinning and Smelting' module). As well as stripping the gold from the carbon, the elution process incorporates an acid wash stage, which removes inorganic foulants from the carbon. Foulants reduce the activity, and hence
Electrowinning
Electrowinning is defined as the hodic 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.

Electrometallurgical Processing SpringerLink
Electrowinning is an electrochemical process employed to extract metals such as copper, zinc, nickel, manganese and cadmium from their solutions. The electrolytic cell is the basic device used in this process, consisting of an inert anode, such as lead or titanium, and a hode, placed in an aqueous electrolyte containing the metal solution.
Electrowinning an overview ScienceDirect Topics
Operation of the electrowinning process differs depending on the elution procedure that is used. In the case of Zadra elution, where the electrowinning cell is in series with the elution column, the column and cell must be designed to elute and recover the gold by recirculation of the eluant until the gold content of the eluted carbon is low enough (<100 g/t) to be reactivated and returned to
