    Chapter 18 Flotation ScienceDirect

    In mineral flotation itmon to supercharge the air to provide a slight excess pressure to give a greater amount of air per unit volume of pulp. The amount of air specified by cell manufacturers is usually in the range 0.52 m 3 air per minute/m 3 pulp, and for use in coal flotation, the figure is towards the bottom end of this range.
