白云鄂博铌资源特征及开发利用新进展

对白云鄂博铌资源特征、选矿技术进展及发展趋势做了详细评述,指出白云鄂博矿石性质复杂是铌资源难以有效利用的主要因素,单一选矿工艺处理白云鄂博铌资源研究较少,主要是重选、磁选和浮选等工艺联合选别以及化学选矿,针对铌资源开发利用存在的问题,提出了先采用传统选矿方法预选富集获得铌精矿,再进行氯化焙烧处理的思路,对该铌资源的开发利用有良好的应用前景。

Characteristics of Bayan Obo Niobium Resources and New Progress in Its Development and Utilization

The characteristics of Bayan Obo's niobium resources, progress of beneficiation technology and development trend are reviewed detail. It is pointed out that the complex nature of Bayan Obo's ore is the main factor that makes effective use of niobium resources difficult. There are few studies on the treatment of Bayan Obo niobium resources by a single beneficiation process, mainly the combined separation of gravity separation, magnetic separation, flotation and other processes, and chemical beneficiation. In view of the problems in the development and utilization of niobium resources, the idea of first use of traditional beneficiation methods to obtain niobium concentrate by pre-concentration and then chlorination -roasting of the niobium concentrate is proposed, which has a good application prospect for the development and utilization of this niobium resource.
