Flotation Froth
Flotation froth is a process used in the mining industry to physically separate particles based on their ability to adhere to air bubbles. It involves creating a froth containing hydrophobic particles attached to air bubbles, which can then be removed from the liquid phase. AI generated definition based on: Microplastic Pollutants, 2017

Froth Flotation: Factors affecting, Advantages, Disadvantage
Principle of froth flotation. The differences in physicochemical surface qualities of distinct minerals are used in froth flotation. Differences in surface qualities between the minerals inside the flotation pulp become obvious after reagent treatment, and for flotation to occur, an air bubble must be able to attach itself to a particle and raise it to the surface.
