摘　　要：对充气旋流微泡浮选柱在不同充气量条件下煤泥浮选试验表明,充气量为0.5、0.75、1.00 m3/h时精煤产率分别为58.26%、68.17%、73.09%,优先浮出大量煤泥,降低矿浆浓度,对以后研究较高浓度煤泥分选提供了依据,且对精煤进行筛分分析后发现对粗粒煤泥分选效果更好。The inflatable cyclone microbubble flotation column under different conditions are inflated slime flotation tests showed that the amount of inflatable 0.5, 0.75, 1.00 m^3/h when the concentrate yield was 58.26% ,68.17% ,73.09%, rising to a lot of slime priority, lower pulp density, high concentration slurry for subsequent research provided the basis for sorting, screening and analysis of coal were found for coarse slime separator better results.
