Abstract: The property of high phosphorus oolitic hematite ore and difficulties in its dephosphorylation was introduced. The process of physics, direct reduction-magnetic separation, magnetic roasting-low intensity magnetic separation-reverse flotation, reverse floatation, leaching, smelting and other processes for dealing with these type of ore by domestic worker was outlined. The current problems and future endeavors of dephosphorization with this type of ore for now was summarized.

Key words: Oolitic hematite with high grade of phosphorus, Dephosphorization, Reverse flotation, Magnetic separation, Leaching
