Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw 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.

EFFECT OF AUTOGENOUS AND BALL MILL GRINDING ON SULFIDE

With ball mill ground pulps the residual sulfur could not be lowered even at increased levels of collector addition. An electrochemical interaction between grinding media and sulfide minerals is thought to have a greater effect on flotation behavior than breakage characteristics.
