【摘要】 介绍了磁选柱用于精选人工磁铁矿低品位铁精矿及天然磁铁矿磁选过程的细筛给矿，实验室小型试验和现场半工业试验结果表明，磁选柱可作为精选设备，也可代替反浮选精选焙烧磁选低品位铁精矿以及用以代替细筛获得高品位磁铁矿精矿．更多还原

【Abstract】 he paper describes the application of magnetic concentrating column in cleaning theman-made low grade magnetite concentrate and the fine screen feed in the magnetic separation flowsheetof natural magnetite ore. The results of laboratory tests and on-site pilot plant tests have shown that themagnetic concentrating column can be used as cleaning equipment to replace reverse flotation to processthe low grade iron concentrate of roasting-magnetic separation and to replace fine screen to gain highgrade magnetite concentrate.更多还原
