摘要
针对提高某赤铁矿选矿厂的磁选精矿品位进行了浮选柱反浮选脱硅试验研究。结果表明,与传统的浮选机一次粗选、一次精选、三次扫选反浮选工艺流程相比,旋流-静态微泡浮选柱采用一次粗选、一次扫选工艺流程,在给矿品位和精矿品位基本相同的情况下,回收率提高了8.37个百分点。旋流-静态微泡浮选柱在赤铁矿反浮选中的应用,为我国赤铁矿反浮选开辟了一条新的途径。
Research is made on the reverse flotation by flotation column for desilication in order to improve the concentrate of magnetic separation of a hematite ore concentrator. The result indicates that compared to the conventional reverse flotation process consisting of one rougher, one cleaner and three scavengers, the process that adopts cyclonic static microbubble flotation column and consists of one rougher and one scavenger can raise the recovery by 8.37%. The application of cyclonic static micro-bubble flotation column has opened a new route for China＇s hematite reverse flotation.
