摘　　要：针对河南某低品位含铅银矿生产中存在银回收率低、精矿铅品位低的问题进行了选矿综合回收试验研究。在工艺矿物学研究的基础上,试验采用硫化浮选+氰化浸出工艺综合回收银和铅,最终获得的分选指标为:浮选精矿Ag品位7 024 g/t,Ag回收率76.00%;Pb品位13.03%,Pb回收率55.63%,铅可以计价回收。浮选尾矿进行氰化浸出后可回收16.71%的Ag,最终Ag的总回收率为92.71%。In order to resolve the problems of low Ag recovery and low Pb grade,existing in the production of a low- grade silver- lead ore in Henan Province,the process of ＂sulphidizing flotation- cyanidation leaching＂,based on the mineralogical characteristics,was adopted. The flotation concentrates with the grade of 7 024 g / t Ag and 13. 03% Pb were obtained,in which the Ag recovery was 76% and the Pb recovery was 55. 63%. Other 16. 71% Ag was further recovered from tailings leaching,and then the total Ag recovery reached 92. 71%.
