    Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles ( Fig. 17 ). A chemical reagent, called a frother, is normally added to promote the formation of small bubbles. Typical addition rates are in the order of 0.05 to 0.25 kg of reagent per tonne (0.1 to 0.5 lb per ton) of coal feed.
