摘　　要：针对四川某磁黄铁矿含量高、铅锌品位低、矿物共生关系密切的铅锌矿石进行了选矿工艺试验研究。采用铅优先浮选-磁选脱硫-锌硫混浮再分离的工艺流程,可获得Pb品位62.37%,回收率86.75%的铅精矿,Zn品位46.46%,回收率83.13%的锌精矿,S品位39.10%,回收率82.37%的硫铁精矿,试验指标良好,实现了铅锌硫的综合回收,为经济合理开发该类矿石提供了一定参考。The mineral processing close association among minerals flotation, a magnetic separation of of a Pb-Zn ore containing high content of pyrrhotite,low grade of Pb and Zn with from Sichuan was investigated. Adopting a flowsheet consisting of a Pb selective desulphurization, and a Zn-S separation of mixed flotation concentrate, Pb concen- trate with Pb grade and recovery of 62. 37% and 86. 75% ,Zn concentrate with Zn grade and recovery of 46. 46% and 83. 13%, S concentrate with S grade and recovery of 39. 10% and 82. 37%, respectively, were produced. The experimental results showed good indexes with the realization of the comprehensive recovery of Pb-Zn-S resources and provided some reference to the economic and rational exploitation of this type of polymetallic ore.
