Abstract: Molybdenum tailings of Liaoning were comparatively coarse grained，75.16% above 0.074 mm.The iron grade of ore was 7.26% and magnetic iron was its major existence form，there were definite phenomenon of enrichment in grain level range from 0.074 to 0.038 mm.Recycling magnetic iron minerals from the tailings was conducted.Results showed that through process including one stage low intensity magnetic separation，one stage middle magnetic separation，and then regrinding middle magnetic separation concentrate and second stage low intensity magnetic separation，concentrates of two stages low intensity magnetic separation mixed and then cleaning by magnetic levitation separator，final iron concentrate obtained with iron grade of 59.12%，iron recovery of 70.05%.
