摘要： 煤炭洗选过程中会产生大量的煤泥，实现对煤泥的分选，不仅可以提高煤炭资源的利用率，还可以增加企业的
经济效益。因此，非常有必要选择合适的分选工艺对煤泥进行分选。考虑到煤泥粒度分布范围较广，多采用重介质分选工
艺。通过分析重介质分选的原理、设备和流程，探讨了影响分选效果的因素。最后，以山西A矿为例，分析了煤泥重介质
分选的效果，发现对煤泥进行回收可以创造显著的经济效益。所分析内容可以为重介质分选工艺的设计提供一定的参考。

Abstract: A large amount of coal slime is produced in the process of coal washing, and the separation of coal slime can not only
improve the utilization rate of coal resources, but also increase the economic benefits of enterprises. Therefore, it is very necessary
to select a suitable separation technology to classify coal slime. Considering the wide range of particle size distribution of coal
slime, the dense medium separation technology is mostly used. By analyzing the principle, equipment and process of dense
medium separation, the factors affecting the separation effect were discussed. Finally, taking A Mine in Shanxi as an example, the
effect of coal slime dense medium separation was analyzed, and it was found that the recovery of coal slime can create significant
economic benefits. The analysis can provide some reference for the design of dense medium separation technology.
