froth flotation depends on differences in surface properties between coal and shale. air bubbles are generated within an aqueous suspension of fine coal with a solids concentration of less than 10%. the hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.
