Abstract: To economically and efficiently reduce the phosphorous content in high phosphorus oolitic hematite ore of wushan, taohua county so as to gain a qualified iron concentrate, based on the study of the ore properties, tests were made on its beneficiation by physical process, chemical process and by their combined process.The results indicate that a combination of gravity separation and chemical processes can reduce the phosphorous content of the ore from 1.13% to 0.077%, which meets the state standard on the phosphorous content in iron ore at a low cost.Moreover, the dephosphorization solution can be recycled and will cause no pollution to the environment.Therefore, it is an efficient method for phosphorous reduction of high phosphorus oolitic hematite ore.
