摘　　要：以某高砷高硫铜锌矿为研究对象,采用优先浮选工艺依次回收矿石中的铜、锌矿物,在铜浮选阶段以25号黑药为硫化铜矿物捕收剂,以氧化钙和腐殖酸钠作为毒砂、黄铁矿以及闪锌矿抑制剂,在锌浮选阶段以EF1108为硫化锌矿物捕收剂,以氧化钙和腐殖酸钠为毒砂和硫铁矿的抑制剂,达到了铜、锌矿物高效回收的目的。研究以高选择性捕收剂EF1108代替传统的黄药类药剂作为硫化锌矿物的捕收剂,起到了在较低碱度下(pH 11.5)高效抑制毒砂和黄铁矿的作用。Taking a high arsenic and high sulfur copper zinc ore as the research object,a preferential flotation process is adopted to recover copper and zinc minerals from the ore.In the copper flotation stage,black catching agent No.25 is used as the collector of copper sulfide,calcium oxide and sodium humate are used as inhibitors of arsenopyrite,pyrite and sphalerite.In the zinc flotation stage,EF1108 was used as the collector for zinc sulfide minerals,and calcium oxide and sodium humate were used as inhibitors for arsenopyrite and pyrite,efficient recovery of copper and zinc minerals was achieved.In this study,the highly selective collector EF1108 was used as the collector of zinc sulfide minerals instead of the traditional xanthate agents,which played a high effect on the inhibition of arsenopyrite and pyrite at low alkalinity(pH 11.5).
