【摘要】 概述了一次浮选、二次浮选、二次尾矿或中矿返回浮选三种典型煤泥浮选工艺流程,阐述了以煤泥可浮性试验结果为依据,合理选择和制定浮选工艺流程的设计思路和方法,指出大型选煤厂往往煤源广泛、煤质差异大,应采用可灵活转换一次浮选与二次浮选的工艺流程。更多还原

【Abstract】 This paper described the three kinds of typical slime flotation processes including primary flotation,secondary flotation and re-flotation of tailings or middlings in secondary flotation,presents that based on the slime floatability test result,reasonable select and make the design ideas and methods for flotation technological process,and points out that due to the feed raw coal from different sources in large sized coal preparation plant,caused big difference in coal quality,so that should use the technological process which can make the primary flotation and secondary flotation flexible interconversion更多还原
