Study on Electrochemical Performance of Dimensionally Stable Anodes during Zinc Electrowinning [PDF]
In zinc electrowinning, small amounts of manganese ions additives are needed in the electrolyte to reduce the corrosion of anodes and minimize the contamination of cathodic zinc by dissolved lead.

Atmospheric curing of zinc sulfide concentrate by sulfuric acid below 300°C [PDF]
Because the traditional roasting-leaching-electrowinning zinc hydrometallurgy process has a small sulfuric acid sales radius and a high inventory pressure, the process of direct leaching zinc concentrate is gaining popularity, but the pressurized ...

ZINC ELECTROWINNING USING REACTIVE ELECTRODIALYSIS (RED) [PDF]
ABSTRACT This paper presents an alternative process for the conventional zinc electrowinning, which consists of a cell of two compartments separated by a anion exchange membrane.One of them contains a zinc sulphate catholyte and sulfuric acid while the anolyte solution contains ferrous sulfate and sulfuric acid.By using a membrane the classical lead ...

Fluidized bed electrowinning of zinc from chloride electrolytes [PDF]
Abstract The fluidized bed electrowinning of zinc from chloride electrolytes has been studied in a laboratory cell. The cell was operated at superficial current densities in the range 1200–7500 A/m 2 with catholytes containing up to 62 kg/m 3 Zn and up to 28 kg/m 3 HCl.
