Abstract: There is 41.07% iron in a low intensity magnetism iron ore.Iron mainly exists in hematite-limonite ore，with distribution rate of 80.33%，few iron carbonate，ferrosilite，magnetite.To provide technique basis for development of the ore，beneficiation experiment was conducted.Results indicated that，at the grinding fineness of -0.074 mm 92.28%，via high gradient high intensity magnetic separation，at pulsating stroke is 4 mm，pulsating speed of 180 r/min，background magnetic induction intensity is 1.0 T，magnetic medium diameter is Φ2+1.5 mm，by one roughing-two scavenging，concentrate of scavenging mixed and via cleaning process，iron concentrate with iron grade of 60.08% and recovery of 75.94% was obtained.With different diameter rod combination as high gradient magnetic separation medium can improve the separation index.
