Conversion practice of the flotation and slime-water treatment system at Sunzhuang Coal Preparation Plant

Directing at the problems confronted in flotation and slime water treatment at Sunzhuang Coal Preparation Plant and analyzing the coal slime properties, a new flotation technology then defined that: flotation of original pulp instead of thickened pulp; employing the newest design of cyclonic static flotation bed with micro bubbles instead of conventional flotation machine; and converting the clarification method for wash water. After such conversion, ash content of clean coal reduced, clean coal yield increased, remarkable economical and social benefit achieved.
