|Abstract: ||Froth flotation of alumina particles was studied by employing electrogenerated oxygen and hydrogen gas bubbles. The effect of current density was studied over a range of 0.1 to 1.6 kA/m(2). Compared to hydrogen, the use of oxygen bubbles at any given gas evolution rate resulted in a higher flotation recovery. The existence of an optimum current density for each given particle size was indicated. Flotation at higher current densities resulted in better flotation kinetics, while flotation at lower current densities resulted in better gas utilization.|
