ZINC ELECTROWINNING USING REACTIVE

Zinc electrowinning using reactive electrodialysis (RED) in an acid environment, and employing the Fe 2+ to Fe 3+ oxidation as the anodic reaction appears to be a real alternative zinc recovery. The RED process is very sensitive to stirring, so kinetics are initially under mixed control and

Electrowinning of zinc - Cominco Ltd.

This example illustrates the operation of a unit of 30 electrolytic cells in an existing commercial zinc electrowinning plant. The cells are arranged in two rows of 15 cells, each containing 49 anodes and 48 cathodes. The unit was operated according to the conventional method of operation which consisted of feeding 180 L/min electrolyte from ...

Zinc Chloride Electrowinning

2017-8-11  The zinc chloride content should be maintained in the range of 52 to 58 wt-pct zinc chloride, for electrolysis from the ZnCl2-KCl-NaCl electrolyte system at 500° C, to achieve optimum energy efficiency and to avoid formation of sludge at the electrolyte-molten metal interface. At higher zinc chloride content, excessive evaporation will occur.

The electrowinning of cadmium in the presence of

2010-12-1  The electrowinning of cadmium in the presence of zinc has been investigated. As such, the effects of initial cadmium concentration (40–160 g/L), current density (50–150 A/m 2), free acid concentration (0–196 g/L), initial zinc concentration (20–120 g/L), and temperature (25–70 °C) on current efficiency (CE) and specific power consumption (SPC) in electrowinning of cadmium have been ...
