摘要
我国是世界上最大的煤炭生产和消费国。随着采煤机械化程度的提高,原煤粒度越来越细且灰分很高,导致高灰细泥细粒煤的分选成为选煤界的一大难题。文章针对高灰细泥细粒煤的分选现状,综述了一些比较典型的用于高灰细泥细粒煤浮选的技术,并指出了高灰细泥细粒煤分选的发展方向。
China is the largest country in coal production and consumption in the world.Recently,with the increase of degrees of mechanization in coal mining,the particle size of raw coal more and more finer and with high ash content,which result in big problem for separating high ash content fine coal in coal preparation industry.According to the current situation of high ash content fine coal separation,the paper presents some typical flotation technologies for separating of high ash content fine coal,also points out the direction of high ash content fine coal separation.
