In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics. Air quantity can be defined on the basis of the narrow range provided in major U. S. commercial cells, for escape velocity, which averages near 1.2 m/min (4 ft /min).

The flotation rate parameters as regressed in Circuit A were used without modification in this setup. Nine flotation rates were used, for PGMs, chromite and gangue in the roughers, scavengers and cleaning section. The flotation cells were run at different froth depths for this test, as recorded in the published dataset.

Minerals. Agitated flotation cells are widely used in the mineral processing industry for separating, recovering, and concentrating valuable particulate material from undesired gangue. Their performance is lowered, however, when part of the particulate system consists of fines, with particle diameters typically in the range from 30 to 100 μm.
