Prediction of bubble size distribution in mechanical

mechanical flotation cells by F. Sawyerr, D.A. Deglon, and C.T. OConnor* Synopsis A bubble population balance model is proposed for the prediction of Sauter mean bubble diameters in mechanical flotation cells. In the model, the flotation cell is treated as two separate, statistically homogeneous zonesthe impeller zone, and the bulk tank zone.

In mechanical flotation cells, power intensity of 1 to 2 kw/m 3 is common [14]. Thus, according to Equation (13), an impeller peripheral speed of m/s (impeller diameter of 0.07 m and impeller speed of 800 to 1000 rpm) is suitable for the laboratory flotation experiments.

An inherent limitation with the flotation of fine partcles in conventional cells is recovery of hydrophilic (gangue) particles by mechanical entrainment in the water reporting to the froth. The method of minimizing entrainment is to create a 53Ocm thick froth at the slurry surface. The froth permits the gangue to drain back to the pulp while

In treating oily water from oil refineries, the separation of oil by mechanical flotation is called froth flotation. It is achieved by adding an organic coagulant or demulsifying agent. Flotation units are constructed with three or four cells in series. Froth flotation by injection of air may also be used for the separation of surfactants.
