• ZnSO4 * aq solution obtained by acidic dissolution of ZnO is subjected to electrolysis at an electrolyte temperature of not more than 40 °C.
• In the hydrometallurgical method of producing zinc, firing is carried out to obtain a cinder of the powder at a temperature of 800-1000 °C. High dispersion of the cinder contributes to its rapid and complete leaching in a solution of sulfuric acid.
