Abstract:In recent years, with the depletion of lead sulfide resources, the exploitation and utilization of lead oxidized resources has attracted more and more attention. Sulfide flotation is the most economic and effective method to recovery of lead oxidized minerals, and cerussite have the most commercial value in lead oxidized minerals, so the sulfidization of cerussite becomes the key issue in lead oxidized resources development. This paper briefly introduces kinds of sulfidization methods, analyzes their advantages and disadvantages, summarizes and analyzes the surface sulfidization and its influencing factors. It is important to correctly understand the nature of cerussite sulfidization and study the influencing factors of sulfidization on this basis.
