本文介绍了弱磁—强磁—浮选流程选别包头白云鄂博中贫氧化矿工业分流试验结果,对其若干技术关键进行了系统的讨论,分析了主要选别作业的选别效果和主要矿物的分选行为,探讨了综合回收铌、钪的可行途径。认为该新工艺流程不仅能有效地回收铁和稀土,而且为铌、钪等综合回收提供了可行途径。 This paper introduces the results of industrial weak-oxide ore splitting in Baotou Bayan Obo by field weakening-ferromagnetism-flotation process and discusses some key technologies of the technology. The effects of the main sorting operations and the main minerals The separation of behavior, discussed the comprehensive recovery of niobium, scandium feasible way. It is considered that the new process can not only effectively recover iron and rare earth, but also provide feasible ways for the comprehensive recovery of niobium and scandium.
