| Abstract: | The preparation of zinc sulfate from the waste mechanical parts of zinc and iron alloy is introduced. The copper and arsenic can be removed by filter. Most iron can be removed through jarosite process. The content of zinc sulfate can reach more than 98% by evaporating, cooling, crystallization and centrifuging. |
