Abstract

Chloride ions, which at concentrations above 100 ppm cause serious problems in zinc electrowinning, can be eliminated by electrolytic oxidation. The rate of the process is controlled by diffusion. Investigation by voltammetry with Pt/Ti stationary and rotating disc electrodes showed that an increase in zinc sulphate concentration is accompanied by a decrease in diffusivity, resulting from an increase in viscosity. Diffusivity can be estimated by measuring the viscosity.<br />Chloride ions, which at concentrations above 100 ppm cause serious problems in zinc electrowinning, can be eliminated by electrolytic oxidation.
