摘要: 某选铁尾矿中的有用矿物主要为黄铁矿、闪锌矿和辉钼矿,主要脉石矿物有石榴石、石英、方解石等。为高效回收其中的有用矿物,实现资源的高效利用,进行了选矿试验研究。结果表明,锌、钼、硫含量分别为0.86%、0.023%、10.09%的试样采用1粗3精3扫锌钼硫混浮、1粗4精1扫抑硫浮锌钼流程处理,最终获得了锌、钼品位分别为41.53%、0.797%,锌、钼回收率分别为92.87%、67.26%的锌钼混合精矿,以及硫品位为51.75%、回收率为91.51%的硫精矿,实现了有用矿物的充分回收。

Abstract: The useful mineral of an iron ore tailings are mainly pyrite, sphalerite and molybdenite, and the main gangue minerals are garnet, quartz, calcite, etc. In order to recover the useful minerals in the iron ore tailings and realize the high efficient resource utilization, experimental study on mineral processing of the iron ore tailings has been conducted. The results showed that for the iron ore tailings containing 0.86% Zn, 0.023% Mo and 10.09% S, the zinc, molybdenum and sulphur minerals could be recovered from the iron ore tailings by zinc-molybdenum-sulphur bulk flotation with one roughing three cleaning three roughing, and zinc-molybdenum flotation separation from sulphur minerals with one roughing four cleaning one scavenging. With the process concerned above, zinc-molybdenum mixed concentrate of 41.53% Zn and 0.797% Mo with recoveries of 92.87% and 67.26% and sulfur concentrate of 51.75% S with recovery of 91.51% could be obtained.
