Abstract

The cause of transformation of slime-water treatment system in the Xingfa Coal Preparation Plant is analyzed. The main characteristics of new technological process are introduced. It is pointed that using flotation column and pressure filter as flotation clean coal pressure filter can improve slime-water processing capacity and clean coal yield in the case of keeping a consistency in the raw material coal property and feed coal concentration.
