摘要: 为了客观、全面、准确了解不同直径棒介质丝组合而成的组合式棒介质及单一直径棒介质对高梯度磁选效果的影响,基于“单元介质”分析法,采用SLon-100周期式脉动高梯度磁选机对铁品位为38.10%的赤铁矿石进行了选矿试验。结果表明,3+2 mm组合棒介质(上8层Φ3 mm棒介质+下8层Φ2 mm棒介质)既有利于对粗粒级的回收,对细粒级的回收效果也不错,因而对全粒级的回收效果较理想;相同类型棒介质丝的组成方式不同分选效果差异较大,因此,最佳排列组合方式应通过试验确定。

Abstract: Beneficiation experiments were conducted on a hematite ore with 38.10% Fe by SLon-100 Cycle Type Pulsating High Gradient Magnetic Separator based on "unit medium" analysis method so as to objectively,comprehensively and accurately understand both the combined rod medium of various diameters and the rod medium of single diameter affecting high gradient magnetic separation.The results indicated that 3+2 mm combined rod medium (upper eight layers withΦ3 mm rod medium,under eight layers withΦ2 mm rod medium) can recover the coarse magnetic particles,and also the fine particles.It can get well recovery index for the whole particles.With the same type of rod matrix,there will a large different separation performance for various arrangements.Thus,the optimum arrangement should be determined by experiments.
