摘要

ABSTRACTThe present invention provides a method forflotation and recovery of fine granulated coal.The water slurry of fine powder coal with5 - 20% by weight of a binder added, based on the purecoal matter, is stirred to manufacture the water slurryof fine granulated coal having a particle size of100 - 250 µm.100 - 200 ppm of a frother or a flotation agentwith a frother base, based on the fine granulated coal,is added to the above-mentioned water slurry of finegranulated coal to recover the fine granulated coal byflotation.
