Flotation ore dressing Britannica

Most kinds of minerals require coating with a water repellent to make them float. By coating the minerals with small amounts of chemicals or oils finely ground particles of the minerals remain unwetted and will thus adhere to air bubbles. The mineral particles are coated by agitating a pulp of ore water and suitable chemicals; the latter bind to the surface of the mineral particles and make them hydrophobic.
