| 摘 要： | 针对云南某含银锡多金属硫化矿石矿物组成复杂、有用矿物易浮难分的特点，采用铅锌混合浮选-混浮精矿铜铅分离浮选-混浮尾矿锌硫依次浮选工艺流程及特别研制的新型捕收剂EMS-01A对其进行选矿试验，成功实现了铜、铅、锌、银、硫的综合回收。通过动电位测试和红外光谱研究了EMS-01A与各目的矿物的作用机理，结果表明，EMS-01A可在黄铜矿和方铅矿表面发生强烈的化学吸附，而在闪锌矿和黄铁矿表面的吸附作用较弱，这为铜铅与锌硫的分离提供了保障。

| Abstract: | In view of characteristics of complex ore components，and easily-floation but hard-separation of valuable minerals for a silver-tin poly-metallic sulfide ore，the beneficiation tests were carried out by the process of zinc-tin mixing flotation- copper-lead flotation of mixing concentrate-zinc-sulfur flotation of mixing tailing with new-type special collector EMS-01A，and then copper，lead，zinc，silver and sulfur were recycled successfully.The reaction mechanism between EMS-01A and the target minerals was investigated by Zeta-potential tests and IR spectrum analysis，which indicates that the chemical adsorption is realized strongly on chalcopyrite and galena surface by EMS-01A while the absorption on sphalerite and pyrite was comparatively weak.This provides a guarantee for separation of Cu-Pb and S-Zn. |
