摘　　要：通过单矿物浮选试验研究黄铜矿和铜离子活化后的铁闪锌矿在Z-200作用下的浮选行为,以及六偏磷酸钠对它们可浮性的影响。研究结果表明:用Z-200作捕收剂,六偏磷酸钠作抑制剂,黄铜矿和铜离子活化后的铁闪锌矿在pH 8～10范围内具有很好的浮选分离效果;实际矿石浮选试验表明,六偏磷酸钠和硫酸锌组合应用于铜锌分离中,对锌矿物能起到较好的抑制作用,从而达到铜锌分离的目的,但仍存在问题,需要进一步研究与优化。The flotation behavior of chalcopyrite and Cu - activitatded marmatite with O - isopropyl - N - ethyl thionocarbamate （ Z - 200） and the effect of sodium hexametaphosphate on their float- ability were studied by single mineral tests. The results show that the selective separation of chal- copyrite from Cu - activitatded marmatite could be achieved at the pH value range of 8 - 10 when using O -isopropyl- N -ethyl thionocarbamate as collector and sodium hexametaphosphate as de- pressant. The results of the real ore tests shows that the combination of sodium hexametaphosphate and zinc sulfate can depress zinc minerals effectively and outputs a good result in separating zinc from copper minerals, but with some problems which need further research and optimization.
