云南某铅锌矿山每年会产生10万 t 浮选尾矿，该浮选尾矿含铁8．72％，含硫0．94％，含磷0．14％，其他杂质含量不高，如果直接对尾矿进行堆储，会使矿山成本压力增大、资源浪费。对此，采用弱磁选—强磁选—浮选脱硫的联合工艺流程来获得粗精矿，其中浮选采用一粗一扫的流程，硫铁矿的活化剂为 H2 SO4和 MHH －1混合而成。通过弱磁—强磁—浮选的联合工艺流程，可获得产率为10．64％的铁精矿，其中 Fe 品位为58．03％，S 含量为0．20％，P 含量为0．09％，综合回收率为70．81％。
雲南某鉛鋅礦山每年會產生10萬 t 浮選尾礦，該浮選尾礦含鐵8．72％，含硫0．94％，含燐0．14％，其他雜質含量不高，如果直接對尾礦進行堆儲，會使礦山成本壓力增大、資源浪費。對此，採用弱磁選—彊磁選—浮選脫硫的聯閤工藝流程來穫得粗精礦，其中浮選採用一粗一掃的流程，硫鐵礦的活化劑為 H2 SO4和 MHH －1混閤而成。通過弱磁—彊磁—浮選的聯閤工藝流程，可穫得產率為10．64％的鐵精礦，其中 Fe 品位為58．03％，S 含量為0．20％，P 含量為0．09％，綜閤迴收率為70．81％。

A lead -zinc mine in Yunnan produces annually 100 000 t of flotation tailings.Flotation tail-ings contains iron 8.72%,sulfur 0.94%,phosphorus 0.14% and other impurities.Direct storage of tailings pile can lead to increase mine cost pressures and waste of resources.The rough concentrate was obtained by using weak magnetic -intensity magnetic separation -flotation desulfurization joint process, where in the flotation process uses a thick and sweep process.H2 SO4 and MHH -1 are mixed as activa-ting agent of pyrite.Experimental studies showed that,qualified iron concentrate could be obtained by a joint process of weak magnetic separation -strong magnetic separation -flotation desulfurization,which the Fe content is 58.02%,the impurities content of sulfur,phosphorus are respectively 0.20% and 0.09%,and comprehensive recovery rate is 70.81%.
