It is previously known to recover zinc electrolytically according to the electrowinning principle by using a silver-bearing lead anode and as the electrolyte a zinc sulfate solution which contains zinc 50-65 g/l and sulfuric acid 100-180 g/l. The cathodes used in this case are aluminum sheets on which zinc is deposited electrolytically.

Grain refiners can be added to help produce a uniform and well-bonded zinc coating on the steel. Electroplating is applied to steel sheets and wires, and are therefore used in applications similar to galvanizing a continuous sheet or wire. The most common applications are in the automotive industry and equipment mountings and fasteners.
