Electrowinning zinc from a sulfate solution - GoldRefiningWiki

The sources for my process is the contaminated zinc sulfate solution from the breakup cell. Most of the copper has already been electrowon by this stage so the remaining solution contains minor parts of copper, nickel, iron, magnesium, tin and other. For the electrowinning step to work we need to remove any traces of metals more noble than zinc.
