Abstract: The paper analyzed the ore properties of oolitic hematite in Western Hubei.And the contrast study on reduction roasting -magnetic separation effect of this oolitic hematite and that of several domestic typical refractory oxidized iron ores found that the magnetization effect of roasting for oolitic hematite ore from western Hubei was much different from those for hematite, limonite and siderite ores under same magnetizing roasting conditions.The mechanism for reduction roasting of oolitic hematite ore was discussed and analyzed.It is proposed that a way of adopting flash magnetizing roasting-magnetic separation process after reducing particle sizes of feeding (below 0.2 mm), and is a promising approach for recovering the oolitic hematite ore in western Hubei province.
