The electrolysis stage is a fascinating process which takes a little over 22 hours. Using large amounts of electricity, pure zinc is deposited on aluminum plates . These plates, which carry pure zinc, are lifted out of the cells. Machines strip off the zinc and the empty plates are returned to the cells where the process starts all over again.
