Zinc: smelting, producing and classification-Metalpedia
Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. The process works by passing an electric current through the solution in a series of cells. This causes the zinc to deposit on the cathodes (aluminium sheets) and oxygen to form at the anodes.extraction of zinc by electrolysisGold Electrowinning Equipment.

EFFECT OF NICKEL AND MAGNESIUM ON ZINC .
Abstract - Zinc electrowinning is performed with the application of a current through insoluble electrodes (Pb-Ag), causing the electrolysis of zinc sulfate, with or without impurities, and zinc deposition on the cathode of aluminum. The impurities can reduce the current efficiency and increase the energy consumption in zinc electrolysis.Merrill Crowe Systems – Denver Mineral EngineersWith a rich pregnant solution, the zinc will be better utilized, and conversely, with a weak pregnant solution it will be less utilized.
