STUDY OF THE PROCESS OF PRODUCING ZINC SULFATE SOLUTION FROM ZINC-CONTAINING CONCENTRATE OF THE KHANDIZA DEPOSIT
Journal Title: International scientific journal Science and Innovation - Year 2024, Vol 3, Issue 6
Abstract
The aim of the study is to study the effect of the process of calcining zinc concentrate from the Khandiza deposit on the degree of zinc extraction and fractional composition. For this, the chemical composition of the concentrate was established and it was shown that the main components are zinc, silicon, potassium, calcium, iron, copper, cadmium, and lead. Titanium, manganese, cobalt, and molybdenum are also contained in small amounts. Extraction of zinc from a concentrate, calcined at 900°C for 90 minutes with sulfuric acid with concentration of 18-25% in an autoclave at a temperature of 75°C, a ratio of Zn:H2SO4=1:1.05 and process duration of 90 minutes allows achieving the degree of extraction 91%. The optimum roasting temperature of the concentrate is 900°C and the duration of calcination is 90 minutes. The main share of 92.1% zinc-containing concentrate calcined under optimal conditions is a fraction of -0.140 mm and 3.6% a fraction of -0.165 - + 0.140 mm. The possibility of obtaining zinc sulfate from the zinc-containing concentrate of the Khandiza deposit is shown. To do this, the calcination process must be carried out at a temperature of 900°C and a process duration of 90 minutes. The degree of extraction of zinc increases from 71% to 91%.
