Silicone glycol collectors in the beneficiation of fine coal by froth flotation
Patent
·
OSTI ID:6507077
A froth flotation process for the beneficiation of fine coal is disclosed which employs as a collector a water-dispersible polyorganosiloxane or a mixture of water-dispersible polyorganosiloxanes which contain organic radicals selected from the group consisting of polyethylene oxide and polypropylene oxide radicals. The process of this invention is especially useful for the beneficiation of difficult-to-float fine coals.
