    EVALUATION OF FROTHER PERFORMANCE IN COAL 2017-5-23 · 276 S. BHATTACHARYA AND S. DEY. Originally, it was believed that the function of a frother was only frothing, i.e., it only acts or gets adsorbed on the liquid=air interface, of creating bubbles in parts of the coal-preparation plant where froth is not beneficial. Frothers also need to be inexpensive, nontoxic, and to not on the coal
