摘　　要：采用一段磨矿－部分混合浮选－混精铜铅分离、混选尾矿选锌流程及无氰药剂，提高了精矿品位及铜、铅、锌、银回收率。工业试验指标为：铜精矿铜品位由１６．４３％提高到２５．３１％、含铅由２７．８２％下降到１２．６４％；铅精矿铅品位由６３．３２％提高到６５．１０％、含铜由２．８７％下降到０．７２％；锌精矿锌品位由４４．６８％提高到４７．４３％。铜、铅、锌、银回收率分别为７２．５６％、８７．６０％、６７．２６％和８６．２６％，与原工艺相比、分别提高了４６．７０％、２．６２％、１．４８％和７．３３％。新工艺已成功转产，使矿山取得了明显的经济效益。Higher selective composite collectors and combined depressants without cyanide were used in part-bulk flotation and Cu-Pb separation of Pb-Zn ore containing silver and copper. By using this new technology,the concentrate quality and recovery can be greatly increased.The grades of Cu,Pb,Zn concentrates obtained in industrial test were 25. 31% Cu,65.10% Pb and 47.43% Zn respectively,and recoveries were 72.56% Cu,86.60% Pb,67.26% Zn and 86.26% Ag.The recoveries have been increased by 46.70% Cu,2.62% Pb,1.48% Zn and 7.33% Ag respectively compared with the previous process technology.Great profits have been gained from this process.
