Since the confirmation of nanobubbles’stable existence on hydrophobic surfaces in 2000, researchon their stability has developed rapidly with numerous related reports, leading to widespread applications of nanobubblesacross various scientific fields. In flotation, theoretical studies related to nanobubbles have become increasinglycomprehensive. Currently, the mechanism of how nanobubbles influence the flotation of fine particle minerals is a keyresearch focus. To deepen the fundamental theory of fine particle flotation, the enhancement mechanisms of nanobubblesin fine particle mineral flotation were systematically summarized, mainly including the enhancement mechanism ofbulk nanobubbles on the flotation process, the interparticle force mechanism induced by surface/interface nanobubbles,the mechanism of liquid film rupture on mineral surfaces induced by surface/interface nanobubbles, and the influencemechanism of surface/interface nanobubbles on particle surface hydrophobicity. Based on this analysis and the currentresearch status of nanobubble⁃enhanced fine particle flotation, research gaps regarding the impact of nanobubbles onmineral particle flotation were identified, providing new research ideas and technical approaches for nanobubble flotationtechnology of fine particles.
