Promoters for froth flotation of coal
Patent
·
OSTI ID:6156670
This patent describes a froth flotation process where solid coal particles are selectively separated under coal froth flotation conditions as a froth phase from remaining solid feed ash particles as an aqueous phase in the presence of a coal particle collector and a frother. The improvement is characterized by the addition of an affective proportion of a hydrophobic, non-ionic promoter comprising a C/sub 12/-C/sub 30/ fatty alcohol or its C/sub 3/ or higher alkoxylated derivative.
