As the most effective method of fine particle, the flotation is 20 playing a more and more important role. But in our country, the phenomenon of flotation running coarse particles often appears in the preparation plant. It will bring to the enterprise serious economic loss and safety accidents. The article summarizes and analysis the harm, causes, control strategy, effect about the flotation running coarse particles, and then put forward the own proposals. It has certain guidance and reference for the practical production. 25 Keywords: Flotation running coarse particles; Harm; Causes; Control strategy; Effect 0 引言 [1] 浮选是目前处理细煤泥最有效的分选方法之一，是选煤厂煤泥水系统的核心 ，对选煤 厂经济效益的提高起着非常重要的作
