COMPARATIVE ANALYSIS OF TECHNOLOGICAL PARAMETERS OF ZINC ELECTROLYSIS IN DOMESTIC AND FOREIGN PRACTICE

Abstract

The article presents a comparative analysis of the technological parameters of the zinc electrolysis process. Zinc electrolysis is carried out in 480 electrolytic cells divided into two series of 240 each, under conditions of a current density of 560–610 A/m² and a current efficiency of 88–91%. The zinc concentration in the neutral electrolyte is 100–135 g/L, while in the spent electrolyte it ranges from 40 to 55 g/L. The use of surface-active substances such as bone glue and antimony additives (0.1–0.3 mg/L) ensures the formation of a dense cathodic deposit without dendrites. The addition of licorice root extract reduces sulfate mist in the electrolyte and enhances the environmental safety of the process. Compared to foreign methods, the local technology is distinguished by its high energy efficiency and operational stability.
