Froth floatation process: This process is based on the fact that the sulphide ore particles are only moistened with oil, whereas oxide and gangue particles are moistened by water. For this, the powdered ore is mixed with water and a little pine oil and whole mixture is then stirred vigorously through rotating paddle by blowing compressed air. The oil forms a or froth with air. The …

for froth formation. As fallowed, the flotation froth is a three-phase system. The frother concentrates at the interface of water and air bubbles, forming an envelope around the bubbles, which prevents them from colliding or touching. Frothers also lower the surface tension of the water. The forces created around the air bubble in the presence of a
