RESEARCH OF KINETIC CHARACTERISTICS OF THE PROCESS OF DECOMPOSITION OF ZINC CONCENTRATE WITH HYDROCHLORIC ACID

Abstract

The aim of the study was the theoretical justification of the kinetic characteristics of the process of producing zincchloride from zinc concentrate of the Khandiza deposit. For this, the effect of temperature and dura tion of the process of autoclave zinc extraction in a 28% hydrochloric acid solution was studied at a ratio of Zn: HCI = 1:1.1. Variable parameters were the temperature of 70, 80 and 90 °C and the duration of the leaching process of 6, 8 and 10 hours. The optimal parameters for the production of zinc chloride were determined.
