Experimental research on coal slime flotation process based on orthogonal test desig

  • 摘要: 汪家寨选煤厂煤泥含量大、灰分较高,在-0.5 mm粒级煤泥混合浮选工艺中出现了跑粗或细泥夹带现象。为了充分回收煤泥中的可燃体,利用煤泥筛分、浮沉试验及分步释放试验对该厂的煤泥性质进行了分析,采用正交试验设计方法分别对煤泥混合浮选、分级浮选与二次浮选3种流程进行试验研究。研究结果表明,二次浮选工艺最适宜该厂的煤泥浮选,可有效降低高灰细泥对精煤的影响,降低浮精灰分;该厂最佳浮选条件为煤泥入浮浓度为80 g/L、煤油耗量为240 g/t、2号油耗量为120 g/t,浮选完善指标为45.63,浮选精煤产率为69.93%,灰分为11.88%,各因素的主次关系为2号油耗量>煤泥入浮浓度>煤油耗量。
    Abstract: Coal slime content and ash content is high in Wangjiazhai Coal Preparation Plant, in -0.5 mm graded coal slime mixed flotation process, it often appeared coarse or fine mud entrainment phenomenon. In order to fully recover combustible materials in the coal slime, the properties of coal slime in this plant were analyzed by slime sieving test, float and sink test and step release test, and three flotation processes of coal slime mixed flotation, classification flotation and secondary flotation were tested and studied by orthogonal experimental design method. The results show that the secondary flotation process is the most suitable for coal slime flotation in the plant, which can effectively reduce influence of high ash fine slime on cleaned coal and the ash content of the flotation cleaned coal. The optimum flotation conditions of the plant are coal slime concentration of 80 g/L, kerosene consumption of 240 g/t and No.2 oil consumption of 120 g/t, improved flotation index of 45.63, flotation cleaned coal yield of 69.93%, ash content of 11.88%, the primary and secondary relationship of each factor is No.2 oil consumption > coal slime flotation concentration > kerosene consumption.
