Abstract: Lingyang iron ore of Jilin linjiang contains the hematite,magnetite,limonite and siderite,which has a complex Fe composition and structure.And the gangue mineral as chamosite was easy to be slimed.So this kind of ore is a refractory one.The experiments of roasting-magnetic separation for the iron ore showed that at a suitable condition,the Fe concentrate reached up to 60.83% at an iron recovery of 64.1% and Fe grade in tailing of 27.60% by the roasting-magnetic separation,thus laying a foundation for application of Lingyang iron ore in Jilin Linjiang.

Key words: Refractory iron ore, Roasting-magnetic separation, Hematite
