    These fine particles then mix with water into a slurry, feeding into a flotation cell. An agitator at the bottom of the cell stirs the slurry also called pulp and suspends the particles in the mix. Air supplied to the cell through the agitator creates bubbles, which rise to the top of the tank, creating the froth.

    DESCRIPTION: Mixed liberated particles can be separated from each other by floatation if there is sufficient difference in their wet ability. The floatation process operates by preparing a water suspension of a mixture of relatively finely sized solids. This is usually done in an agitated chamber open at the top. Fine bubbles of air are then dispersed through the agitated suspension to form a
