Zinc Chloride & Electrowinning

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.
