Atmospheric curing of zinc sulfide concentrate by sulfuric acid below 300°C [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2022 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]
Journal of the Chilean Chemical Society, 2014 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]
Hydrometallurgy, 1985 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.
