摘    要：对西藏某含高砷锑金矿石进行了选矿试验研究。试验采用的工艺流程:优先浮选锑,使锑砷分离,从分离浮选后的尾矿中回收金。试验指标:锑精矿品位63.30%(含As 0.48%,Pb 0.14%),锑回收率59.74%;金精矿品位9.08 g/t,金回收率88.19%。试验获得的锑精矿达到一级品级,并充分回收了金。

Abstract: The experimental flotation studies are carried out on antimony-gold ores containing high-arsenic in Tibet.First,preferential flotation for antimony is applied to separate antimony and arsenic,and then gold is recovered from the tailings of antimony-arsenic separation.As a result,the antimony concentrate grade is 63.30 % and the recovery rate is 59.74 %;the gold concentrate grade is 9.08 g/t and the recovery rate is 88.19 %.The study obtains First Class antimony concentrate and recovers gold sufficiently.
