This document discusses the innovative advancements in the leaching processes of zinc concentrates, emphasizing both atmospheric and pressure leaching methods. The objective is to enhance zinc recovery from complex mixtures by detailing the Roast-Leach-Electrowin process and its key components. Methodologically, the outline includes the steps involved in roasting zinc sulfides, the chemical reactions associated with leaching zinc oxides, and the treatment processes for complex concentrates. Results highlight the efficiency of capturing roaster off-gases to produce sulfuric acid, integrated techniques for zinc recovery from ferrites, and methods for purifying zinc solutions before electrolytic extraction. By employing strong acid leaching and zinc dust cementation, the study also discusses the removal of impurities like copper, cadmium, cobalt, and nickel from zinc solutions, leading to high-purity zinc production. Overall, these developments contribute significantly to improving the economic viability and environmental sustainability of zinc extraction processes.
