The amount and quality of concentrate obtained from froth flotation of a coal are very important to determine the efficiency of the separation process. The shape and size of the bubbles in the froth directly affect the amount and purity of the concentrate overflowed during the froth flotation of the coal. The froth structure is significantly dependent on parameters such as the size of the

froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.

REDESIGN OF INDUSTRIAL COLUMN FLOTATION CIRCUITS

Once the froth is out of the flotation cell, it should break down rapidly to allow pumping of the concentrate. The mineral-laden froth is also referred to as concentrate or in coal flotation “the float product”. 1.1.3 Flotation Machines Froth flotation is performed in machines specifically designed for that purpose.

"Coal cleaning by froth flotation " by Choon Han

When a micro-bubble flotation technique was employed to float Appalachian coal, it produced a cleaner coal product than conventional macro-bubble flotation;A general kinetic model was proposed to represent the rate of flotation of coal. For two Appalachian coals, the model successfully represented the flotation kinetics of uniformly sized coal.
