Abstract: In order to improve the resource utilization rate of a high-phosphorus oolitic hematite，a roasting-magnetic separation-leaching process for iron extraction and phosphorus reduction was proposed in view of the complex symbiotic relationship between iron minerals and phosphorus minerals and the diffi‐ culty in efficient utilization of conventional beneficiation methods. The experimental process conditions were optimized in the process of grinding-magnetic separation and sulfuric acid leaching dephosphoriza‐ tion. The test results show that under the conditions of grinding fineness of -0.038 mm95%，magnetic field strength of 95.54 kA/m，sulfuric acid dosage of 0.2 mol/L and reaction time of 20 min，the iron concentrate with total iron grade of 64.43%，total iron recovery of 96.54%，phosphorus grade of 0.18% and yield of 85.17% was obtained by the whole process test，which can provide guidance for other high phosphorus iron ore to increase iron and reduce phosphorus.
