Fundamental Research in Utilization of an Oolitic Hematite by Deep Reduction

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