| Abstract: | A high phosphorus oolitic hematite ore in Chongqing with a head grade of 38.52% TFe and containing 1.1% P,mainly exists in the form of oolitic hematite and limonite ore.When the normal mechanical mineral processing method is adopted,it′s difficult to reach the aim of iron increase and phosphorus decrease.However,when the technological flowsheet of roasting-magnetic separation-reverse flotation is adopted,the iron concentrate of 58.15% TFe and 0.28% P with a yield of 46.16% and an iron recovery of 69.37% are obtained. |
