Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation of iron ores, magnesite ores, and scheelite ores are summarized, and the main problems and mechanisms that diminish the separation efficiency of minerals are revealed in detail. Recent research progress on the flotation of these ores has confirmed that mineral aggregation, coating, and dissolution, as well as other factors caused by interacting behavior, explain the depressing effects of fine particles on mineral separation. Solvable methods for these effects are further discussed. Novel flotation processes and more selective reagents are critical for further investigations on various approaches to improve the beneficiation efficiency of these ores. This review aims to provide a good reference for conducting studies related to complex ore flotation.

泡沫浮选是用于分离细粒矿物的最有效的工业方法。复杂浮选的主要问题是浆液中矿物之间相互作用的负面影响，导致分离过程中表面性质的变化。本文综述了矿物间相互作用对铁矿石，菱镁矿和白钨矿浮选的影响，并详细揭示了降低矿物分离效率的主要问题和机理。这些矿石浮选的最新研究进展已证实，矿物的聚集，覆盖和溶解以及相互作用行为引起的其他因素，可以解释细颗粒对矿物分离的抑制作用。进一步讨论了解决这些问题的方法。新型浮选工艺和更多选择性试剂对于进一步研究提高这些矿石的选矿效率的各种方法至关重要。这篇综述旨在为进行与复杂矿石浮选有关的研究提供良好的参考。
