Electrodeposition of Zn-Mn alloys from recycling battery leach solutions in the presence of amines [PDF]

, 2010
The recovery of metal ions by electrodeposition from solutions resulting from the lixiviation of spent Zn-MnO2 batteries was studied. It was attempted to optimise the electrodeposition process, the selectivity of ion-separation, the morphologic ...

Behavior of arsenic in zinc electrowinning

Transactions of Nonferrous Metals Society of China, 2010
Abstract The effects of arsenic on the cathode polarization process in zinc electrowinning, its kinetics equation, parameters and polarization mechanism were studied by multiple electrochemistry approaches. The experimental results show that, if [As3+]⩾3 mg/L, electrowinning first enters into stationary passivation range, and then enters into ...

Towards Using MMO Anodes in Zinc Electrorefining: Mn Removal by Simulated Plant Off-Gas

Metals, 2023
Implementing mixed metal oxide (MMO) anodes in zinc electrowinning is highly desired due to the considerable reduction in electrical energy consumption. However, the presence of manganese in the electrolyte is a major obstacle for implementing MMO anodes
