EMD Deposition on Mn2O3/Ti Anode for Manganese Recovery from Zinc
On the other hand, zinc electrowinning solutions typically contain Mn(II) ions coming from zinc ore and such Mn(II) ions are oxidized to MnO 2 on lead alloy anodes during electrowinning of zinc. The deposited MnO 2 finally drops off from the anode surface and makes a sludge that also contains some other elements, e.g., lead, strontium, and ...Web
