摘要:
针对某低品位铅锌银多金属矿石铅锌分离的工艺流程、药剂制度、银的回收进行了试验研究，确定了适合该矿石的优先浮选工艺流程。结果表明：优先浮选闭路流程可获得相对较好的指标，银主要富集在铅精矿中；铅精矿中铅、锌、银的品位分别为45.52 %、2.26 %、2 470 g/t，铅、银的回收率分别为73.24 %、58.16 %；锌精矿中锌、铅、银的品位分别为32.64 %、0.50 %、178 g/t，锌、银的回收率分别为65.86 %、2.50 %；硫精矿中硫品位为36.18 %、硫作业回收率为43.25 %。铅、锌、银、硫得到了较为有效的分离与回收，为该多金属矿石的回收利用提供技术支撑。

Abstract:
Experimental study is carried out on the lead and zinc separation process,reagent regime and silver recovery of a low grade lead,zinc and silver polymetallic ore and the preferential flotation process suitable for the ore is determined.The results show that the preferential closed-circuit flotation flowsheet can obtain relatively good index and the silver is mainly enriched in lead concentrates; in the lead concentrates,lead,zinc and silver grade is 45.52 %,2.26 % and 2 470 g/t respectively,and lead and silver recovery rate is 73.24 % and 58.16 % respectively; in the zinc concentrates,zinc,lead and silver grade is 32.64 %,0.50 % and 178 g/t respectively,and zinc and silver recovery is 65.86 % and 2.50 % respectively; in the sulfide concentrates,sulfur grade is 36.18 % and sulfur recovery rate is 43.25 %.The lead,zinc,silver and sulfur are effectively separated and recovered.The study can provide technical support for the recovery of the polymetallic ore.
