SILICONE GLYCOL COLLECTORS IN THE BENEFICIATIONOF FINE COAL BY FROTH FLOTATIONAbstractA froth flotation process for the beneficiation offine coal is disclosed which employs as a collector a water-dispersible polyorganosiloxane or a mixture of water-dispersible polyorganosiloxanes which contain organicradicals selected from the group consisting of polyethyleneoxide and polypropylene oxide radicals. The process of thisinvention is especially useful for the beneficiation ofdifficult-to-float fine coals.
