Experimental Study on Suspension Magnetization Roasting-Magnetic Separation of an Iron Ore
-
Abstract
The iron grade of a certain iron ore was 56.36%. The iron of raw ore mainly existed in the forms of hematite and limonite. The gangue minerals were chiefly quartz and bauxite. Therefore, a suspensionmagnetization roasting-magnetic separation process test was conducted on the ore. The results indicated that the optimum conditions for reducing roasting are as follows: The size of feed is -0.074 mm 56.11%, with roasting temperature 560℃, concentration of CO 30%, and roasting time 15 min. Under the optimum roasting conditions, the roasted products were ground to -0.074 mm 95%, and then magnetic separation was carried out to produce aniron concentrate with iron grade of 64.42% and iron recovery of 94.49%. It also provides a solution for other refractory iron ores.
