摘要： 四川某铅锌矿含铅 5.24%，含锌 0.63%，伴生银含量 30.23 g/t，属于典型含铅锌银多金属硫化矿。为了实现该矿产资源的高效利用，针对原矿矿物种类多、嵌布关系复杂、铅锌含量差异显著、铅锌分离难度大等问题，进行了矿石工艺矿物学和选矿试验研究。试验结果表明：采用石灰+硫化钠作为组合调整剂、D301+25^# 黑药作为复合捕收剂，通过 1 粗 3 精 2 扫工艺流程，可获得铅精矿铅品位 59.13%、含锌 2.49%、铅回收率 94.05%、伴生银品位 267.40 g/t、银回收率 73.68% 的选矿指标，实现了铅和伴生银的高效回收。

Abstract: A lead-zinc mine in Sichuan contains 5.24% lead，0.63% zinc and 30.23 g/t associated silver，which belongs to a typical lead-zinc-silver polymetallic sulfide ore.In order to realize the efficient utilization of the mineral resources，aiming at the problems of many kinds of raw ore minerals，complex dissemination relationship，significant difference in lead and zinc content，and difficult separation of lead and zinc，the ore process mineralogy and beneficiation test are carried out.The test results show that using lime + sodium sulfide as a combined regulator，D301+25# ammonium butyl aerofloat as a composite collec⁃ tor，through the process of one roughing，three cleaning and two scavenging，the lead concentrate with lead grade of 59.13%，zinc content of 2.49%，lead recovery rate of 94.05%，associated silver grade of 267.40 g/t，silver recovery rate of 73.68% can be obtained，and the efficient recovery of lead and associat⁃ ed silver is realized.
