摘　　要：为了研究潘集选煤厂某外来煤煤泥的可浮性,以可燃体回收率以及浮选完善指标作为两个考查指标,采用正交试验方法来研究捕收剂用量、起泡剂用量以及矿浆浓度对煤泥的浮选影响规律。试验结果表明:通过考查指标的极差以及方差研究,捕收剂用量对煤泥浮选是高显著影响,起泡剂用量以及矿浆浓度对煤泥浮选有显著影响。In order to study the floatability of a foreign coal slime in Panji Coal Preparation Plant,using recovery of combus⁃tible and flotation perfection index,the orthogonal test method was adopted to study the effect of collector dosage,foaming agent dosage and slurry concentration on coal slime.The test results show that,by investigating the range and variance of the indicators,the amount of collectors has a significant effect on slime flotation,while the amount of foaming agent and slurry concentration have significant effects on slime flotation.
