| Abstract: | The paper describes the characteristics of Baiyunerbo oxide ore resource, the present status of its beneficiation and metallurgical separation technology, discusses the problems in BaoSteel's conventional beneficiation-blast furnace process such as low rear-earth recovery, not high resource comprehensive utilization rate and serious environment pollution, and analyzes the necessity to make a comprehensive utilization of Baiyunerbo oxide ores. Based on this, a new process of coal-based direct reduction and beneficiation for treating this kind of ore is proposed, and its feasibility and advantages for the comprehensive utilization of Baiyunerbo oxide ores are discussed. It is concluded that this process can recover the valuable elements such as iron, rear-earth, niobium and thorium in a comprehensive way and therefore, has a good development prospect. |
