摘　　要：根据四川某高泥氧化铅锌矿中铅、锌氧化率高,且白铅矿、菱锌矿、褐(针)铁矿密切共生的特点,采用硫化-黄药浮选法(SXF)+硫化-胺浮选法(SAF)对铅、锌进行回收。结果表明,浮铅阶段使用水玻璃和腐殖酸钠组合药剂作为矿浆调整剂,可有效地抑制矿泥对浮选的影响;采用先硫后氧原则并使用异丁黄作为浮铅阶段捕收剂,半闭路试验获得铅精矿中铅品位与回收率分别为66. 10%、88. 29%;浮锌阶段采用十二胺作为捕收剂、硫化钠作为硫化剂、ZnSO4作为调整剂,半闭路试验获得锌精矿中锌品位与回收率分别为19. 41%、87. 09%。The sulfur-xanthate flotation(SXF)and the sulfide-amine flotation(SAF)were used to recover lead and zinc from the lead-zinc oxide ore,and the good target of flotation is obtained.Based on the characteristies of the close association of Cerussite,Smithsonite and limonite(goethite)and high oxidation rate in a lead-zinc oxide ore.Cerussite and galena were floated selectively using sodium humate and Na 2SiO 3 as combined depressant for slime and isobutyl xanthate as Collector for Cerussite and galena in the lead-flotation phase.it was a lead concentrate assaying 66.10%Pb with88.29%recovery.Smithsonite was floated selectively using ZnSO 4 as modifier,laury lamine as collector and Na 2S as curing agent in the zinc flotation phase.It was a zinc concentrate assaying 19.41%Zn with 87.09%recovery that was achieved from the lead-zinc oxide ore in semi-closed circuit tests.
