Abstract:The preparation methods of nanobubbles in recent years and their effects on mineral flotation behavior were reviewed in this paper, including the generation of bulk nanobubbles and the preparation of interfacial nanobubbles. Moreover, the effects of nanobubbles on the flotation probability of fine particles, the difference of particle surface properties and the influence of particle recovery size also were summarized. On this basis, the mechanism of nanobubble enhanced fine particle flotation was expounded, which provides the research direction for the basic research and application of nanobubble flotation technology.
