Abstract:.Theprocess of the high pressure roller and dry magnetic separation of Mongolianmine was introduced. The Mongolian iron ore produced by high pressure rollgrinding was applied to discard plenty of coarse tailing in advance and thesmall particles ratio increased significantly. Iron concentrate with grade of over60% and magnetite concentrate with grade of 58.59% were obtained .Iron recoveryrate of 92.77% and magnetite recovery rate of 96.12% were reached. Theexcellent indexes were achieved.
