摘　　要：某多金属金矿石矿物组成复杂,金矿物嵌布粒度微细,属典型的高砷高硫微细粒难处理金矿石。依据矿石特性,确定采用优先浮选金、铅-金铅尾矿浮选锌及硫砷分离回收剩余金的工艺技术路线,并通过详细深入的试验研究,较好地解决了该高砷高硫微细粒复杂多金属难处理金矿石的选矿技术难题,获得了较理想的技术经济指标。该成果已被该多金属金矿500 t/d选矿厂设计采用。This polymetallic gold ore is a refractory ore mainly because of its complicated mineralogical composition, superfine dissemination size of gold minerals, thus it is a typical refractory gold ore containing high As and S. According to the ore characteristics, the technological flowsheet of selective flotation of gold and lead, then, recovering remaining gold from tailings is adopted. Based on detailed experimental research, several technical problems experi- enced in treating process of this refractory gold ore have be satisfactorily solved, and the techno-economic index obtained is well too.
