    Evaluation of Frother Types for Improved Flotation

    Initial froth flotation tests involved identifying the volumetric feed flow rate that resulted in a near optimum separation performance (i.e., maximum coal recovery and ash rejection). The feed flow rate was varied from 300 mL/min to 2000 mL/min at a constant feed solids concentration of 5% by weight. The optimum feed volumetric flow rate was determined to be 1000 mL/min. As such, all of the

    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. Within this general macroscopic view of the flotation process as a whole, several distinct micro processes can be identified. Each of these plays a role in determining how individual solid
