摘　　要：对某地高泥贫赤铁矿进行了选矿工艺试验研究。结果表明:采用阶段磨矿-弱磁获精-强磁抛尾-重选(摇床)流程,在入选原矿品位TFe24.07%、一段磨矿细度-0.074mm占50%、二段磨矿细度-0.074mm占95%的条件下,可获得产率19.35%、品位65.89%、回收率52.33%的最终综合精矿。The mineral processing experimental research was carried out on a high mud content lean hematite. The results showed that using the technological flowsheet of stage grinding-low intensity magnetic separation for obtaining concentrate-high-intensity magnetic separation for discarding tailingsgravity separation（shaking table）＂, a final iron concentrate with TFe grade of 65.89% ,yield of 19.35% and iron recovery of 52.33% from the raw ores with TFe grade of 24.07% was obtained,with the first stage grinding size being 50% -0. 074mm and the second stage,95%-0. 074mm.
