摘　　要：鲕状赤铁矿是我国一种重要的铁矿石资源,但由于其组成结构特殊,采用常规选矿的方法尚不能实现有效分选。采用深度还原与分选工艺处理某鲕状赤铁矿石,通过试验确定了深度还原的主要条件,所得产品的铁品位、金属化率和铁回收率分别在85%、97%和92%以上。Oolitic hematite is an important iron ore resource. Because of its special feature,it can not be effectively 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%.
