| Abstract: | The coal- based direct reduction- magnetic separation was adopted to deal with the high phosphorus oolitic hematite after the mineral composition and structure of this ore were identified by XRD and SEM, and the factors which effected the process were studied and analyzed. The results show that the optimum process condition is temperature of 1250??, time of 30min, carbon/oxygen ratio of 1. 8 and basicity of 0. 8, under this condition , the magnetic concentrate yield is 47. 68%, concentrate grade is 86. 51%, recovery rate of iron is 92. 94%, phosphorus content is 0. 18% and metallization rate is 92. 56%, the recovery rate of phosphorus of tailing is 92. 88%. |
