14/12/2015  Regulation of Mechanically Agitated Flotation Cells. The great advantage of mechanically agitated machines is that every cell can be regulated separately, and that reagents can be added when necessary at any one of them. Since, as a general rule, the most highly flocculated mineral will become attached to a bubble in preference to a less floatable particle, in normal operation the aeration in the

Flotation Cell - an overview ScienceDirect Topics

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 froth, and have sufficient
