某含金银高硫微细粒铜锌矿石中有用矿物粒度微细，黄铜矿与闪锌矿、方铅矿、毒砂关系密切，且硫高达21．44％。针对该矿石性质特点，试验探索了铜锌优先浮选、铜锌等可浮浮选、铜锌硫等可浮浮选、铜锌混浮—铜锌精矿再磨—铜锌分离、铜锌硫混浮—精矿再磨—铜锌硫分离等5种选别流程。试验结果表明：铜锌硫混浮—精矿再磨—铜锌硫分离流程适宜处理该矿石，其技术指标较好；同时，硫精矿（金银粗精矿）采用湿法工艺进行处理，也取得了良好的技术指标。
某含金銀高硫微細粒銅鋅礦石中有用礦物粒度微細，黃銅礦與閃鋅礦、方鉛礦、毒砂關繫密切，且硫高達21．44％。針對該礦石性質特點，試驗探索瞭銅鋅優先浮選、銅鋅等可浮浮選、銅鋅硫等可浮浮選、銅鋅混浮—銅鋅精礦再磨—銅鋅分離、銅鋅硫混浮—精礦再磨—銅鋅硫分離等5種選彆流程。試驗結果錶明：銅鋅硫混浮—精礦再磨—銅鋅硫分離流程適宜處理該礦石，其技術指標較好；同時，硫精礦（金銀粗精礦）採用濕法工藝進行處理，也取得瞭良好的技術指標。

The useful mineral particles in one gold and silver contained copper-zinc ore are micro-fine with high content of sulfur,chalcopyrite is closely related to sphalerite,galena,and arsenopyrite,and the content of sulfur is as high as 21.44%.In this paper,according to the characteristics of the ore properties,five processes are explored inclu-ding selective flotation of copper and zinc,the flotation capacity of copper and zinc,the flotation capacity of copper, zinc and sulfur,mixed flotation of copper and zinc-regrinding of copper and zinc concentrates-separation of copper and zinc,mixed flotation of copper,zinc and sulfur-regrinding of concentrates-separation of copper,zinc and sulfur. The results show that the process of mixed flotation of copper,zinc and sulfur-regrinding of concentrates-separation of copper,zinc and sulfur is well suited for the treatment of the ore with good technical indexes;at the same time it a-chieves good technical indexes with sulfide concentrates( gold and silver roughing concentrates) subject to metallurgi-cal treatment method.
