| 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。

| Abstract: | 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. |
