Hematite ore's magnetic characteristics were significantly impacted by magnetizing roasting. By selectively magnetizing roasting, hematite is transformed into magnetite. With an Fe grade of 65.25% at a recovery value of 72.5% in the concentrate, magnetic separation produced the greatest result for Fe.
In this paper, the mineral beneficiation process for hematite is studied, where the technique of screening-roasting-grinding-magnetic separation-dewatering is adopted. According to Fig. 1, the raw ore is classified into particle ore that is 0–15 mm in size and lump ore larger than 15 mm in size during the screening unit process.
