The electrolyte used in the commercial production of electrolytic zinc from zinc sulphate solutions contains small amounts of impurities each of which has its own effects upon the process. Impurities such as antimony, cobalt, nickel, and iron tend to lower the current efficiency while other impurities such as chlorine, fluorine, and nitrates tend to increase the corrosion of the lead anodes and thereby increase the lead tenor of the zinc deposit.
