摘　　要：分析了传统旋流微泡浮选柱的应用现状,阐述了浮选入料性质及条件特别是入料浓度对浮选柱分选效果的影响,提出了采用预浮选式旋流微泡浮选柱分选解决高浓度细粒煤浮选的新方法,并通过试验论证了该方法的可行性,对工业现场的浮选作业具有一定的指导意义。Analyzed the present status of traditional cyclonic microbubble flotation column, influence of flotation feed property and conditions, especially feed concentration to flotation colomn performance were elaborated. Utilization of pre - flotation cyclonic microbubble flotation column to slove the flotation of fine coal with high concentration was proposed. And the feasibility of this method was experimentally testified, which is of guidance significance for flotation in industrial field.
