Preparation of Ti/PbO2-ZrO2 Composite Anode for Zn Electrowinnig

International Journal of Electrochemical Science, 2018
To improve the oxygen evolution electrocatalytic activity of Ti/β-PbO2 in zinc electrowinning, the Ti/β-PbO2-ZrO2 electrodes were prepared by anodic oxidation electrodeposition in the lead nitrate plating bath containing ZrO2 nanoparticles.

Utilization of Galvanizing Flue Dust Residue: A Sustainable Approach towards Complete Material Recycling

Metals
During hot-dip galvanization, wastes such as bottom dross, zinc ash, spent pre-treatment solutions, and galvanizing flue dust (GFD) are generated. In scientific publications, research devoted to GFD waste recycling is absent, and companies generating ...

Influence of manganese on the electrochemical behavior of an aluminum cathode used in zinc electrowinning

工程科学学报, 2018
Pure aluminum is commonly used as the cathode electrode in the traditional hydrometallurgy applications of zinc electrowinning. However, with the decrease of zinc concentrate grade and increase of the impurity ions in the electrolyte, the corrosion ...

Particle Size Refinement of Zn Electrodeposits in Alkaline Zincate Solutions with Polyethylene Glycol and Tween 80

International Journal of Electrochemical Science, 2017
The alkaline zinc electrowinning process can directly recover powdery Zn metal from oxidized zinc ores and industrial wastes. However, the industrial-scale practice shows that the Zn powders produced generally have a broad particle size distribution, and

Kinetic Study of Manganese Oxidative Precipitation Reaction by Using SO₂/Air Gas Mixture

Metals
Removing manganese from zinc electrolytes is necessary to pave the way for replacing lead-based anodes with mixed metal oxide (MMO) anodes. MMO anodes offer significantly lower overpotential towards oxygen evolution reactions, thus are attractive from an
