Abstract: Beneficiation test was carried out on the lean hematite ore from Sijingying, Luanxian County.A process consisting of staged grinding, low intensity magnetic separation-high intensity magnetic separation-anionic reverse flotation was adopted to treat this ore and obtained an iron concentrate grading 65.80% with a yield of 22.97% and a recovery of 69.10%, and a final tailing grading 8.81%.

Key words: Lean hematite ore, Magnetic separation, Anionic reverse flotation
