In order to efficiently develop and utilize an iron ore resource in Inner Mongolia,on the ba-sis of the study of the mineralogical properties of ore technology,the whole process of high-pressure roller grinding,wet magnetic separation,tail throwing,tower mill and magnetic separation was carried out.The results show that the-1 mm particle size fine ore was obtained by the high-pressure roller grinding ma-chine,and the wet pre-separation concentrate with a total iron grade of 36.63%and a magnetic iron grade of 31.31%was obtained under the condition of 400 mT,and the wet pre-separation concentrate tower was ground to-0.030 mm accounting for 95%,and the iron concentrate with an iron grade of 65.78%and a re-covery rate of 66.22%was obtained by one roughing and one cleaning magnetic separation,and the test re-sults could provide a feasible process for the iron ore separation.
