摘　　要：对云南某高硫铅锌矿进行选矿实验研究。原矿铅品位2.98%、锌品位2.79%、银品位114.95 g/t,在磨矿细度为-0.074 mm 76.19%条件下,采用优先浮选工艺流程,以硫酸锌+碳酸钠作为组合抑制剂,以新型捕收剂HQ-Pb作为铅捕收剂,最终获得铅品位56.62%、银品位1915.38 g/t的铅精矿,铅回收率82.36%,银回收率73.44%;获得锌品位45.92%、银品位171.38 g/t的锌精矿,锌回收率82.29%,银回收率7.58%。Study on the mineral processing of a high sulfur lead-zinc ore in Yunnan Province were conducted.Grades of lead,zinc and silver were 2.98%,2.79%and 114.95 g/t,respectively.Ore was ground to-0.074 mm 76.19%and under the condition of selective flotation process,the combined reagents ZnSO_(4) and Na_(2)CO_(3) used as the depressant and HQ-Pb and HQ-Zn were used as a novel galena and sphalerite collector.From the results of closed circuit tests,the lead concentrate,containing 56.62%Pb and 1915.38 g/t Ag,was produced,at recovery of 82.36%Pb and 73.44%Ag.And zinc concentrate of 45.92%Zn and 171.38 g/t Ag,was obtained,at recovery of 82.29%Zn and 7.58%Ag.
