Metallurgy Purification of ores

In this process, the powdered ore is mixed with water and a little pine oil (a foaming agent) and the whole mixture is then stirred vigorously by blowing compressed air. The oil forms a foam (or froth) with air. The ore particles stick to the froth, which rises to the surface; while the rocky, and earthy impurities (gangue) are left in water Fig.. The froth is skimmed off, collected, and allowed to subside to get concentrated ore. (iii)
