Cathode quality is more difficult to control in zinc electrowinning than it is in copper electrowinning. The standard zinc potential (−0.763 V) is lower than many of the impurity metals that can be found in zinc electrolyte solutions. Despite the difficulty, 80% of the primary zinc production is derived by electrowinning .
