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.

Key words: High phosphorus iron ore, Dephosphorization, Chemical beneficiation
