煤炭反浮选降灰研究进展

Advances of Coal Reverse Flotation for Demineralization

结合国内外研究,分析了煤和脉石矿物的表面性质,探讨了反浮选过程中浮选药剂(捕收剂、抑制剂、调整剂等)的选择以及作用机制,并对影响反浮选效果的过程参数以及相关的浮选效果改善方案作了概述,为接下来的研究提供思路。

Combined with both domestic and foreign research, gives an overview of coal reverse flotation for demineralization from the aspects of the surface characteristics of coal and mineral, the choosing and action mechanism of flotation reagents （collectors, depressants, regulators, etc.）, the process parameters that will affect reverse flotation performance, and other methods to improve reverse flotation performance, which will provide reference for the further study.
