Research on the Magnetizing Roasting and Magnetic

Magnetizing roasting is one of the effective ways to improve the comprehensive utilization of refractory iron ores. The factors influencing the magnetizing-roasting of an oolitic hematite ore were studied and the optimal conditions of the process of magnetizing roasting-low intensity magnetic separation were determined to be: 5% anthracite, 850 ℃ roasting temperature, 60 min roasting time
