摘　　要：论述了从贫磁铁矿尾矿中回收铁精矿新工艺.某地贫磁铁矿经圆盘回收机回收后,精矿品位18.21％,经过“预选、阶段磨矿、单一磁选”工艺流程选别,可获得精矿品位64.98％～67.21％,产率20％左右,金属回收率71.5％以上的选别指标.This paper demonstrates the new process of recovery of iron ore concentrates from lean magnetite tailings. After lean magnetite in a certain place is recovered by disc reclaimer, its concentrate grade reaches 18.21%. Through the whole separation process of pre--separation, stage grinding and single magnetic separation, desirable separation result is achieved with concentrate grade of 64. 98%-67.21%, yield rate of 20% or so, and metal recovery rate of above 71.5%.
