Abstract: It is hard to obtain good separation index for the specularite at -1 mm in Jiugang company by conventional beneficiation process.In the conventional magnetic roasting-low intensity magnetic separation，the problem of pellets has to be solved.With Hami bituminous coal as reducing agent，the process of the microwave magnetization roasting-low intensity magnetic separation study for fine ore is carried out to investigate the effect of the dosage of pulverized coal，microwave power，roasting temperature，roasting time，grinding fineness of roasted products and low intensity magnetic field strength on the iron concentrate indexes.The test results showed that under the conditions of the mass ratio of pulverized coal to ore 5%，microwave power 1 kW，and calcined at 550 ℃，the raw fine ores were treated by the microwave magnetizing roasting for 15 min，and then the roasted products are ground to the fineness of -0.074 mm 85.65%.By this method，good indicators of iron concentrate with Fe grade of 55.10% and Fe recovery of 86.65% was achieved by adopting one-stage magnetic tube separation with magnetic field strength of 92.16 kA/m.The research provides a new idea for high efficient recovery of iron ore from fine specularite at -1 mm.
