摘　　要：苏州高岭土尾矿经摇床分选出的硫化矿产品中含铅2.19%、含锌2.94%,采用混合浮选流程,在不磨矿的情况下,用石灰抑制黄铁矿、戊基黄药为捕收剂混合捕收铅锌,得到了铅品位31.67%、铅回收率83.11%,锌品位31.27%、锌回收率68.17%的混合精矿,提高了高岭土尾矿的利用价值。The sulfide minerals which come from Suzhou kaolin tailings contains 2.19% lead and 2.94% zinc.In the case of non-grinding,adopting mixed-flotation process and inhibition of pyrite with lime,mixed collector lead and zinc with amyl xanthate,can access to a qualified mixed concentrate which contains 31.67% lead,83.11% recovery rate and 31.27% zinc,68.17% recovery rate,thereby increase the value of kaolin tailings.
