中文摘要：

为给废旧铅蓄电池铅膏的湿法回收工艺提供理论依据,对湖北金洋冶金股份有限公司破碎分选后的废铅膏进行了XRF、XRD、物理分析及化学分析等,确定了废铅膏的主要成分、理化性质等特性。结果表明,废铅膏粒径细小,碾钵磨细后能过120目的筛下物超过77.4%,这对湿法转化是有利的。废铅膏主要组成为64.5%PbSO4、29.5%PbO2、4.5%PbO、0.8%Pb及其他微量杂质元素,杂质主要包括Fe、Sb和Si等。因此,铅膏湿法处理时应该采取合适的净化工艺。

英文摘要：

In order to provide theoretical evidence for hydrometallurgical process of recovery of lead pastes in spent lead-acid battery,the main compositions,physical and chemical properties of lead pastes were investigated by XRF,XRD,physical analysis,and chemical analysis method.Lead paste samples were obtained from spent lead-acid battery after crushing-separating process in Hubei Jinyang Metallurgical Incorporated Co.Ltd.The results revealed that undersized particles（〈120 mesh） is over 77.4% in lead pastes after manual grinding.Thus the diameter of the lead paste is pretty small,which is favorable for the following hydrometallurgical process.The components of spent lead-acid battery pastes are 64.5% of PbSO4,29.5% of PbO2,4.5% of PbO,0.8% of Pb,and other impurity elements including Fe,Sb and Si etc.Therefore,proper purification should be used in the hydrometallurgical process for recovery of lead pastes.
