摘　　要：云南某锑铅金银矿有价矿物为硫锑铅矿、脆硫锑铅矿、辉锑矿和自然金,脉石矿物主要为石英、长石、云母和角闪石等。采用浮选-重选联合流程,在给矿含锑1.72%、铅1.57%、金1.45 g/t和银25.39 g/t的情况下,获得锑铅金银品位分别为21.91%、17.32%、14.32 g/t和305.72 g/t,回收率分别为87.09%、86.12%、68.79%和83.91%的锑铅金银精矿产品,以及金品位为37.90 g/t,回收率为20.42%的金精矿。An antimony-lead-gold-silver ore from Yunnan province contained valuable minerals such as boulangerite, jamesonite, stibnite and natural gold, main gangue such as quartz, feldspar, mica and hornblende etc. Flotation and gravity separation combined process was applied to process the feedings whose grade of Sb, Pb, Au and Ag separately were 1.72%, 1.57%, 1.45 g/t and 25.39 g/t, the antimony-lead-gold-silver concentrate whose Sb, Pb, Au and Ag grade separately were 21.91%, 17.32%, 14.32 g/t and 305.72 g/t and recovery separately were 87.09%, 86.12%, 68.79% and 83.91%; gold concentrate with Au grade of 37.90 g/t and recovery of 20.42% was obtained.
