The study in the field of surface nanobubbles has received great progresses since surface nanobubbles were imaged with atomic force microscopy in 2000. Meanwhile, the interest in developing new flotation techniques for separating fine particles keeps increasing. Surface nanobubbles are showing a great potential of application in the field of mineral processing. The formation of agglomerations composed of fine minerals and the easier attachment of a mineral particle to a flotation bubble are the mechanism for the improved flotation performance in the presence of surface nanobubbles. In this work, various aspects regarding surface nanobubbles including the methods for generation, measurement and identification of surface nanobubbles, the responses of surface nanobubbles to external stimuli including pH, salts, surfactants, temperature, pressure, ultrasonication et al., where flotation is usually performed are summarized. At last, we reviewed recent progresses for surface nanobubbles in flotation. This review gives perspectives for further research in the future.

自2000年用原子力显微镜对表面纳米气泡进行成像以来，表面纳米气泡领域的研究取得了长足的进步。同时，开发新的浮选技术以分离细颗粒的兴趣不断增加。表面纳米气泡在选矿领域显示出巨大的应用潜力。由细矿物组成的团聚体的形成和矿物颗粒更容易附着在浮选气泡上是在表面纳米气泡存在下改善浮选性能的机制。在这项工作中，关于表面纳米气泡的各个方面，包括表面纳米气泡的产生、测量和识别方法，表面纳米气泡对外部刺激的响应，包括 pH、盐、表面活性剂、温度、压力、对通常进行浮选的超声波处理等人进行了总结。最后，我们回顾了浮选表面纳米气泡的最新进展。本综述为未来的进一步研究提供了展望。
