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

Negative effects of cyanide on health and its removal options from industrial wastewater [PDF]

, 2015
Water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater.

Recovery of Zinc and Rhenium for the Production of Zinc Perrhenates

Crystals
This study outlines findings from an investigation into the development of a hydrometallurgical process for manufacturing various forms of zinc perrhenate, entirely from waste from recycling and from the Zn–Pb industry.

Exploring the mechanisms and interfacial processes of metal electrodeposition [PDF]

, 2015
Electrodeposition of multivalent metal cations in nonaqueous solvents is ultimately more difficult compared to aqueous systems. This is due to lower conductivity and a smaller library of soluble electrolytes.

Eliminating fluoride-induced corrosion of aluminum cathodes in zinc electrowinning by aluminum ion complexation

Journal of Materials Research and Technology
This paper discusses the effect of fluoride on the corrosion behavior of aluminum alloy used as a mother blank in zinc electrowinning, focusing on the mitigation of the corrosive process by aluminum ion addition and fluoride complexation.

The Characterization of Residues Related to the Roasting– Leaching–Electrowinning Zinc Production Route for Further Metal Extraction

Metals
Super-hot acid leach residue is generated during zinc production in the roasting–leaching–electrowinning route, where both primary and secondary resources are used as feed material.
