    Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechanization of coal mining. Flotation offers a very satisfactory lowcost method for recovering a fine, low ash, clean coal product at a profit.
