钽铌矿浮选技术研究进展

Research Progress on the Flotation Technology of Tantalum-Niobium Ores

国内钽铌资源特性相比于国外复杂,需结合重、磁、浮、电、冶或联合工艺对其进行回收。浮选法虽在部分钽铌矿石的选别中不能占主导,但对钽铌钨锡矿等物理性质相近的矿石、钽铌细泥及其他有价金属的回收效果明显,是实现资源综合利用的有效方法。概述了钽铌矿浮选技术的应用现状,重点分析了浮选技术及药剂作用机理的研究成果,指出了上述研究存在的不足,并对钽铌矿在药剂应用与发展方面进行了详细的展望,指出多极性基羟肟酸、有机膦酸有望成为钽铌矿浮选药剂发展的主要方向。

The resource characteristics of tantalum-niobium ore in China is more complicated than that of in abroad, and it should be combined with gravity, magnetic, floating, electricity, metallurgy or combined process for recovering. Flotation method is not dominant in the separation of part of tantalumniobium ore while the recovery effects of tantalum-niobium-tungsten-tin ore,fine tantalum-niobium slime and other valuable metals is obvious,and it is an effective method to realize the comprehensive utilization of resources. Current status of flotation technology of tantalum-niobium ore are summarized. Research findings of flotation technology and action mechanism and their deficiency are systematically introduced.The development prospect of regents is put forward as a result in detail. Hydroxamic acid with multiple polar groups and organophosphonic acid are excepted to be the main development direction of tantalumniobium flotation reagents.
