Vedclass · Answer

(D) The $Froth \ Flotation$ method is based on the difference in the wetting properties of the ore and the gangue particles with water and oil. In this process,the sulfide ore particles are preferentially wetted by the oil (pine oil),while the gangue particles are wetted by water. Since the ore particles become hydrophobic (water-repelling) due to the oil coating,they attach to the air bubbles and rise to the surface as froth,while the hydrophilic gangue particles remain in the water.
