What is Flotation?
Flotation is a separation process that exploits differences in surface chemistry to separate particles from each other or from a liquid. In mineral flotation (froth flotation), air bubbles are used to selectively attach to hydrophobic particles and carry them to the surface, while hydrophilic particles remain submerged. It is one of the most widely used mineral processing techniques.
