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).
