Abstract: Different desulphurization methods for scrap lead paste have been introduced. At this stage, the major methods are pyrometallurgy and hydrometallurgy. The first one is the general used method to recovery scrap lead acid batteries. It shows faster reaction speed, great handing capacity, higher production efficiency and well adapt for raw material, but products secondary pollutants of lead dust and sulfur dioxide on these processes. The second one shows favorable environmental benefit for lower pollution, higher controllability, greater security and higher metal recovery rate, but it exists the problem of higher requirement for production equipment, higher energy consumption and longer technological processes.
