Abstract: Oolitic hematite is an important iron ore resource. Because of its special feature,it can not be effective- ly separated by the conventional beneficiation method. A new reduction and separation process was used to treat an oolitic hematite. The main factors influencing reduction were determined in the test. The main performance indexes of the product from this process were described as follows:iron grade above 85%;metallization rate up to 97%;iron recovery above 92%.

Key words: Oolitic hematite, Deep reduction, Metallization rate
