摘　　要：本文在介绍了杂铜含铅概况,以及目前国内除铅工艺现状。在分析除铅理论的基础上得出了影响除铅效果的三个主要因素:铜液中铅的活度系数、氧化铅的活度、反应平衡常数。简单介绍了目前国内外的几种除铅技术:硅酸盐法、磷酸法、硼酸法及FRHC法。This paper Introduces the general situation or waste Copper polluted by lead and the current domestic method for clearing out lead from Waste Copper by Fire-refining. Basde on the theoretical analysis linferred the three main factors ： the Activity Coefficient of lead on liquid copper, Lead activity, the reaction equilibrium constants. Simply introduces some current domestic Technology ： by silicate, by phosphate, by boric,the FRHC law.
