Abstract:Technological characteristics of waste lead batterie recycling in recent years were briefly described from domestic and global aspect. Lead paste wet desulfurization process and utilization technology of current study were main summarized. The existing methods can be divided into solid-liquid and solid-solid desulfurization technology systems. Characteristics and shortcomings of the existing technologies were compared and analyzed. Key control factors of wet desulfurization process were reviewed from reaction mechanism and model of wet pre-desulfurization. The incomplete reaction caused by product layer coating during desulfurization process was discussed. In response to this problem, shear, collision, grinding and other mechanical strengthening methods were analyzed and confirmed due to their contribution of promoting mass transfer process. On this basis, outlook of grinding-leaching enhanced desulfurization was drawn.
