摘　　要：微细粒矿物由于其特殊的物理化学性质,采用常规选矿方法浮选效率低。载体浮选作为一种有效的微细粒矿物浮选技术,通过采用合适的载体,可显著提高微细粒矿物的浮选效率。阐述了微细粒矿物的表面性质与浮选行为,以及载体浮选的基本原理,载体与微细粒矿物的相互作用机制。分析了微细粒矿物载体浮选技术的研究及应用现状,对载体浮选的影响因素进行了归纳。针对同类载体、异类载体和分支载体三种载体浮选,指出了各类载体浮选的特点和优缺点,并展望了其未来发展趋势,旨在为载体浮选的进一步工业应用提供参考。Due to the special physical and chemical properties of fine-grained minerals,the flotation efficiency of conventional beneficiation methods is low.Carrier flotation,as an effective flotation technology for fine-grained minerals,can significantly improve the flotation efficiency of fine-grained minerals by using suitable carriers.This paper first introduces the surface properties and flotation behavior of fine-grained minerals,as well as the basic principle of carrier flotation and the interaction mechanism between carrier and fine-grained minerals.Thereafter,the research and application status of micro-fine mineral carrier flotation are analyzed,and the influencing factors of carrier flotation are summarized.The characteristics,advantages,and disadvantages of the three kinds of flotation carriers,including similar carrier,heterogeneous carrier,and branch carrier are pointed out,and the future development trend of these carriers has been prospected,aiming to Provide a reference for further industrial application of carrier flotation.
