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

Germanium recovery from zinc calcines using a hydrometallurgical procedure
Revista de MetalurgiaIn the final stage of zinc calcines processing, zinc is recovered by zinc electrowinning. However, the presence of germanium in the electrolyte seriously affects the current density in the electrowinning step. Since germanium is a critical and strategic

Effects of Polymer Additives on Zinc Electrowinning.
Shigen-to-Sozai, 1999 Zn electrodeposition behavior and the morphology of deposited Zn were studied in the electrowinning solution containing polymer additives such as gelatin and polyethylene glycol (PEG). The molecular weight of gelatin and PEG were determined by gel permeation chromatography. During Zn deposition, the cathode potential was shifted to less noble direction
