Abstract: The iron concentrate with iron grade of 58.5%，iron recovery of 78% can be obtained by dealing with specularite particles at 100~15 mm from Jingtie Mountain，Gansu province through the process of furnace magnetic roasting-low intensity magnetic separation-reverse flotation.Iron concentrate with iron grade of only 47.5%，iron recovery of 60% was obtained by dealing with specularite particles at 15~0 mm through the process of grinding-high intensity magnetic separation.In order to improve the beneficiation indexes，the magnetic roasting-magnetic separation experiments on particles at 15~5 mm was conducted.The results showed that iron concentrate with iron grade of 55.80% and iron recovery of 83.97% was obtained at conditions of mass ratio of coal to ore samples at 2%，particle size of coal at 1~0 mm，roasting temperature of 810 ℃，roasting time for 60 min，grinding fineness of roasted products at 80% passing -0.074 mm，and low magnetic field intensity of 91.56 kA/m.
