Abstract: Then paper elaborates on the feasibility of extraction of concentrate from flotation tailings through making technical renovation of the heavy-medium separation and froth flotation processes at the 1.8 Mt/a Enhong Coal Preparation Plant.Through technical reform,the heavy-medium and flotation system can each be made to produce products with targeted ash,thus making it possible to effectively recover the coal lost in flotation tailings for making efficient and full use of coal resources.The renovated flotation process and coordinated product handling system are introduced.
