针对湖南某地尾砂中铜、锌品位低，锌矿物可浮性好，铜锌分离难的问题，采用铜锌混合浮选、铜锌分离的工艺流程，以石灰、硫酸锌、亚硫酸钠为锌硫矿物的抑制剂，乙硫氮为铜矿物的捕收剂，实现了铜锌矿物的有效分离，以及资源的最大化利用，闭路试验获得了含 Cu 17．94％、回收率61．47％的铜精矿，含 Zn 45．43％、回收率59．73％的锌精矿，该工艺为合理开发此类铜锌矿提供了技术支持。
針對湖南某地尾砂中銅、鋅品位低，鋅礦物可浮性好，銅鋅分離難的問題，採用銅鋅混閤浮選、銅鋅分離的工藝流程，以石灰、硫痠鋅、亞硫痠鈉為鋅硫礦物的抑製劑，乙硫氮為銅礦物的捕收劑，實現瞭銅鋅礦物的有效分離，以及資源的最大化利用，閉路試驗穫得瞭含 Cu 17．94％、迴收率61．47％的銅精礦，含 Zn 45．43％、迴收率59．73％的鋅精礦，該工藝為閤理開髮此類銅鋅礦提供瞭技術支持。

In view of the problem of low grade copper and zinc , the good floatability of zinc mineral and the difficult in separation of copper and zinc in tailings somewhere in Hunan , the test adopted the process of copper -zinc mixed flotation -flotation separation of copper -zinc mixed concen-trate.Copper-zinc flotation separation used lime , zinc sulfate and sodium sulfite as the inhibitors of zinc sulfur minerals , and diethyldithiocarbamate as the collector of copper mineral , which real-ized the effective separation of copper -zinc minerals , as well as the maximum utilization of re-sources .Through closed-circuit experiment the copper concentrate with the grade of 17 .94%and the recovery of 61 .47% and the zinc concentrate with the grade of 45 .43% and the recovery of 59 .73%were obtained respectively .This process provided the technical direction for the reasona -ble development of this type of copper -zinc ore, at the same time put forward the effective recover-y approach of low-grade copper zinc mine of the tailings .
