Zinc oxide derived from processing of the slime obtained in an industrial process of electrolytic zinc obtaining was leached with the aqueous sulfuric acid solution. The effect of temperature and time on the extent of leaching was determined. The conditions lead to zinc recovery of about 90%. It was found that the extent of arsenic leaching did not depend upon the time and temperature of leaching. Next the conditions of the solution purification procedure were determined. It was found that jarosite formation as well as the degree of arsenic removal is connected with trivalent iron concentration in the solution.
