Explain froth flotation process with neat diagram.

Explanation

In this processore is powdered and made into a slurry with water. A rotating paddle is used to agitate the suspension in presence of an oil. Froth is formed which carries mineral particles. To this slurry froth collectors and stabilisers are added. Collectors (pine, oil, xanthate) enhance non - wettability of the mineral particles. Froth stabilisers (e.g. cresols, aniline) stabilise the froth. The mineral particle become wet by oils. while gangue particles become wet by water. The froth is light and is skimmed off. The ore particles are then obtained from the froth.
