With the fast development and popularization of electronic equipment and new energy industry, the consumption and demands for lithium are on a rapid rise. Spodumene is one of the important lithium resources, so it is of great significance to concentrate it. Beneficiation methods of spodumene include magnetic separation, gravity separation, and flotation. Since the major gangue minerals of spodumene are quartz and feldspar, flotation becomes the most important way to concentrate spodumene. In this paper, various researches related to spodumene flotation were reviewed. It can be seen that the surface properties of spodumene changed with the variation of size fraction, surface dissolution, isomorphous substitution, and grinding method, which means that different spodumene surfaces showed diverse properties. Metal ions such as Fe3+, Ca2+, and Mg2+ can improve and strengthen the flotation behavior of spodumene effectively, when NaOL or NaOL/DDA is used as a collector. The hydroxy complexes of these ions played an important role in the collector adsorption. In the aspect of spodumene collectors, most of the new spodumene collectors reported were mixed collectors; nevertheless, the number of the researches on spodumene collectors was still limited. This review provided a detailed, comprehensive, and valuable reference source for the current research status of spodumene flotation, and provided references for the future researches to improve and strengthen the flotation behavior of spodumene.

锂辉石浮选的研究现状

随着电子设备和新能源产业的快速发展和普及,锂的消耗和需求正在迅速增加。锂辉石是重要的锂资源之一,因此对其进行浓缩具有重要意义。锂辉石的选矿方法包括磁力分离,重力分离和浮选。由于锂辉石的主要脉石矿物是石英和长石,因此浮选成为浓缩锂辉石的最重要方法。本文综述了有关锂辉石浮选的各种研究。可以看出,锂辉石的表面性质随尺寸分数,表面溶解度,同晶取代和研磨方法的变化而变化,这意味着不同的锂辉石表面表现出不同的性质。铁等金属离子当使用NaOL或NaOL / DDA作为捕收剂时,3+,Ca 2+和Mg 2+可有效改善和增强锂辉石的浮选行为。这些离子的羟基络合物在集电极的吸附中起着重要的作用。在锂辉石收集器方面,报道的大多数新的锂辉石收集器是混合收集器。然而,关于锂辉石收集器的研究数量仍然有限。综述为锂辉石浮选的研究现状提供了详细,全面,有价值的参考资料,为今后研究改善和加强锂辉石的浮选行为提供了参考。
