不同浮选条件下高灰细泥煤浮选洗煤效果分析

Effect Analysis of High Ash Fine Slime Coal Flotation Washing under Different Flotation Conditions

细泥煤的浮选过程难度较大,且高灰细泥的含量对浮选效果具有重要的影响。为提高高灰细泥煤的浮选效果,针对不同的搅拌速度及充气量下的浮选过程进行试验,通过试验所得的煤样进行浮选效果的分析,为高灰细煤泥的浮选优化提供参考。

The flotation process of fine slime is difficult,and the content of high ash fine slime has an important influence on the flotation effect.In order to improve the flotation effect of high ash fine slime coal,the flotation process under different stirring speed and aeration rate was tested,and the flotation effect of coal samples obtained from the test was analyzed,which provided a reference for the flotation optimization of high ash fine slime coal.
