摘　　要：某铜铅多金属硫化矿含银品位77 g/t,主要以辉银矿等独立银矿物形式和以硫化铅矿物为载体的载体银矿物形式存在。在原有生产流程结构基础上,分别对磨矿细度、铜优先浮选作业和铅浮选作业进行了银强化回收试验,试验结果表明,在保证铜铅金属回收完全的前提下,银总回收率提高了5个百分点,实现了共生银矿物的浮选强化回收。A copper-lead polymetallic sulfide ore contains silver of 77 g/t,mainly in the forms of independent silver minerals such as argentite and associated silver minerals carried by lead sulfides.Based on the existing production process,silver flotation tests were conducted in grinding process,copper preferential flotation process,and lead flotation.The results indicate that on the premise of complete copper and lead recovery,the total silver recovery increased by 5%,which realized the strengthened flotation of associated silver minerals.
