The conditioned mineral slurry is then processed in flotation cells, which are essentially agitated tanks into which finely-dispersed air bubbles are introduced. The desired hydrophobic mineral will then attach to the air bubbles and float to the top of the flotation cell, where it will be skimmed off as a mineral-laden froth.
