自 2000年纳米气泡被证实可稳定存在于疏水表面以来,其稳定性研究迅速发展,相关报道大量涌现,纳米气泡也随之在多个科学领域中被广泛应用。在浮选领域,纳米气泡相关的理论研究日益丰富。目前,纳米气泡对微细颗粒矿物浮选的影响机理是研究焦点。为深化微细颗粒浮选的基础理论,系统总结了纳米气泡在微细颗粒矿物浮选中的强化机制,主要包括:体相纳米气泡对浮选过程的强化机理、表/界面纳米气泡引发的颗粒间作用力机制、表/界面纳米气泡诱导矿物表面液膜破裂的机制,以及表/界面纳米气泡对颗粒表面疏水性质的影响机制。在此基础上,根据当前纳米气泡强化细颗粒矿物浮选的研究现状,指明了纳米气泡对矿物颗粒浮选影响的研究重点,为纳米气泡浮选微细颗粒矿物提供新的研究思路和技术途径。
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.
