四川某难选硫铁铅锌矿合理选矿工艺研究

    Research on the reasonable mineral processing technology of a refractory S-Fe-Pb-Zn ore in Sichuan

    • 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。

       

      Abstract: The floatation experiment of a high content of pyrrhotite, low grade and close associated relationship Pb-Zn ore from Sichuan was investigated. Adopting a flowsheet consisting of a Pb selective flotation, a magnetic separation of desulphurization, and a Zn-S separation of mixed flotation concentrate, Pb concentrate 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,and also provided some reference to the scientific and rational recovery of polymetallic ore.
