新型起泡剂对望峰岗选煤厂煤样的实验研究

Study on the influence of foaming agent on coal sample in Wangfenggang coal preparation plant

浮选药剂能扩大煤和其他矿物质的表面差异，从而改善和强化煤泥浮选过程。浮选药剂的种类和用量对浮选效果起着极其重要的作用。以望峰岗选煤厂煤泥为研究对象，选用1号、2号2种新型起泡剂对其进行单元浮选实验，经过不同实验研究，对比考察了其浮选效果，从而证明了新型浮选药剂提高精煤产率、降低精煤灰分的优良性能。

Flotation reagents can expand the surface differences between coal and other minerals, advantage is taken of which to improve and strengthen the process of flotation. The types and amount of reagents play a vital role in flotation performance. Choose the coal slime of Wangfenggang coal preparation plant as subject investigated, two new reagents ： No. 1, No. 2 were used to conduct batch flotation tests to study the effect of its flotation. The results show that the new type flotation reagent can improve the clean coal yield and reduce ash.
