摘　　要：针对东鞍山含碳酸盐铁矿石优先分离出的以菱铁矿为主的中矿产品,采用管式炉还原焙烧-弱磁-再磨-弱磁的工艺,用煤做还原剂时,可获得铁品位60.31%,回收率87.49%的铁精矿。Aiming at midding ore products which siderite take the main part and separated preferred,adopt technology of roasting-low intensity magnetic separation-regrinding-low intensity magnetic separation,reduction roasting magnetic separation test was done by adopt tube furnace.Concentrate with iron grade 60.31% and recovery rate 87.49% could obtained when take coal as reducing agent.
