Model-based Computer Simulation of Froth Flotation
Model-based Computer Simulation of Froth Flotation Kyle Robert Kelley Abstract Froth flotation is a separation process by which particles are selectively attached to air bubbles. It is one of the most dynamically complex industrial processes in use today. This complexity has steered research towards understanding the fundamental principles of ...

Special attention is paid to the mode of interaction between particles and gas bubbles under dynamic conditions in a flotation cell. In contrast to the well known empirical first- order chemical reaction rate model, the solution in the present paper predicts similar but not exactly the same behaviour of the recovery rate.

A more or less stable layer of froth is maintained on the surface of the slurry. Particles that are attached to bubbles will tend to remain attached at air-water interfaces when the bubble enters the froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell.
