| 摘 要： | 为了提高梅山铁矿资源利用率,开展了铁矿尾矿再选工业试验。每年产生90万t品位低、粒度细的尾矿,主要含有赤铁矿和菱铁矿,采用高梯度强磁—螺旋溜槽重选工艺,选出强磁精矿:产率36.63%、品位28.51%,可以用作水泥铁质校正剂;选出螺旋溜槽精矿:产率5.75%、品位48.55%,可以作为配矿原料。应用后能够减少尾矿排放量,具有较大的经济效益和生态环保社会效益。

| Abstract: | For the purpose of improving the resource utilization rate of Meishan iron mine,the re-separation industrial test on iron mine tailings was made. Each year the company produces 900 thousand tons of tailings with low grade and small granularity,containing hematite and siderite. With the process of high gradient high intensity magnetic separation-spiral chute gravity separation,the high intensity magnetic concentrate with 36.63% of productivity and 28.51% of iron grade can be served as cement rectifying raw m... |
