Froth flotation Froth flotation is the most popular method for cleaning the ultrafine coal in large scale commercial operation It relies on the difference of particle surface properties with coal being typically hydrophobic and most of the mineral impurities hydrophilic Small air bubbles are passed through a dilute suspension of coal in water
