how does froth flotation work

The purpose of the flotation cell is to attach hydrophobic particles to air bubbles, so that they can float to the surface, form a froth, and can be removed. To do this, a flotation machine must maintain the particles in suspension, generate and disperse air bubbles, promote bubble–particle collision, minimize bypass and dead spaces, minimize mechanical passage of particles to the …
