| 摘 要： | 阐述了难浮煤泥的特点及改善浮选效果的主要方法。以庞庞塔5号煤泥为浮选试样，研究了一次浮选、精煤再选、分支浮选3种不同浮选流程对难浮煤泥浮选效果的影响，从而找到了适合难浮煤泥浮选的工艺流程。结果表明，分支浮选流程可以在满足精煤灰分的要求下，提高精煤产率。

| Abstract: | Introduce the characteristics of difficult-to-float coal and the main methods to improve the flotation effect. Take Pangpangta NO.5 coal as flotation sample,research the flotation effect of difficult-to-float using three different flotation processes which are one step flotation,clean coal reconcentration and branching flotation process in order to find the best process.The results show that branching flotation process can improve the clean coal yield,and at the same time,control effectivly clean coal ash c... |
