froth flotation method
Answers
well are you in class xi or xii... just asking.
This method is mainly used to remove gangue from sulfide ores. The ore is powdered and a suspension is created in water. To this are added, Collectors and Froth Stabilizers. Collectors (pine oils, fatty acids etc) increase the non-wettability of the metal part of the ore and allows it to form a froth. Froth Stabilizers (cresols, aniline etc) sustain the froth. The oil wets the metal and the water wets the gangue. Paddles and air constantly stir up the suspension to create the froth. This frothy metal is skimmed off the top and dried, to recover the metal.
Hi friend_______,
★ This process depends on the preferential wettability of the ore with oil and the gaunge particles by water.
★ Lighter ores such as sulphide ores are separated by this method.
I hope this would be helpful to you..
