Iron Control Process for Copper Electrolyte - Eichrom ...

As copper is depleted from the CuSO4-H2SO4 electrolyte solution during copper electrowinning, the concentration of iron remaining in the solution increases. This build up of iron can result in a loss of current efficiency in the electrowinning process due to the continuous oxidation/reduction of Fe 2+ to Fe 3+.
