Lead-Silver Anode Degradation during Zinc Electrorecovery Process: Chloride Effect and Localized Damage

Journal of Chemistry, 2013
Using mass-loss, potentiodynamic polarization, and electrochemical impedance measurements under anodic regime, the corrosion behaviour of lead-silver (0.55%) electrode in zinc electrowinning solution containing different concentration of chloride anions ...

A conceptual flowsheet for heap leaching of platinum group metals (PGMs) from a low-grade ore concentrate [PDF]

, 2012
peer reviewedThis research proposes a new conceptual process to economically extract platinum group metals (PGMs), and as a secondary aim, base metals (BMs) from a low-grade concentrate originating from typical PGM concentrator plants.

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 ...
