electrowinning process of zinc from zinc sulfate solution

  • ZincWikipedia

    Zinc is a chemical element with symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table.In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state +2, and the Zn 2+ and Mg 2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes.

  • Removal of heavy metal ions from wastewaters: A review

    Hydroxide precipitation process using CaOH 2 and NaOH in removing CuII and CrVI ions from wastewater was evaluated by Mirbagheri and Hosseini 2005.The CrVI was converted to CrIII using ferrous sulfate. Maximum precipitation of CrIII occurred at pH 8.7 with the addition of CaOH 2 and the concentration of chromate was reduced from 30 mg/L to 0.01 mg/L.
