摘　　要：对某地区难选磁黄铁矿型铅锌硫化矿开展了铅、锌综合回收工艺试验研究。以新型酯类铅矿物捕收剂ZQ⁃11与25#黑药组合作铅捕收剂浮选铅矿物,铅浮选尾矿进行磁选脱硫,脱硫尾矿以丁基黄药作捕收剂浮选锌矿物,在原矿铅品位1.84%、锌品位4.53%情况下,闭路试验获得了铅品位62.57%、含锌3.30%、铅回收率89.49%的铅精矿和锌品位43.37%、含铅1.01%、锌回收率85.79%的锌精矿,实现了难选磁黄铁矿型铅锌硫化矿的有效回收。An experimental study was carried out to comprehensively recover lead and zinc resources from a refractory pyrrhotite lead⁃zinc sulfide ore grading 1.84%Pb and 4.53%Zn respectively.And a new ester collector of ZQ⁃11,in combination with 25#dithiophosphate,was used to float lead minerals.After that,magnetic separation process was adopted to treat lead flotation tailings for desulfurization,and butyl xanthate was then used to collect zinc minerals from the desulfurized tailings.A closed⁃circuit test resulted in 89.49%Pb recovery into a lead concentrate grading 62.57%Pb and 3.30%Zn respectively,and 85.79%Zn recovery into a zinc concentrate grading 43.37%Zn and 1.01%Pb respectively.It is concluded that this process can actualize an effective recycle of refractory pyrrhotite⁃type lead⁃zinc sulfide ore.
