1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry The particles with attached air Froth Floatation Process In this method powdered ore is put in a tank full of which cause the sulphide ore particles to stick with the oil and rise to the surface in the form of froth The gangue particles being heavier remain behind at the bottom of water tank The froth is separated and concentrated sulphide ore is obtained from it
