Froth floatation process : Based on the
difference in wetting properties of gangue
and ore particles. Therefore, ore particles
rise to the surface in the form of froth and
impurities remain in water. For example,
sulphide ores
• Based on preferential wetting of ore
particles by oil (pine oil).
• Ore particles become light and form froth.
• Froth can be stabilised by stabilisers
(aniline or cresols)
