Dahlke and Gomez (2005) showed that in a flotation machine operating in a typical range of the superficial gas velocity J g, the gas holdup e was directly proportional to J g. For a given cell, J g is simply the gas volumetric flowrate Q g, m 3 /s, divided by the area of cross-section of the cell, so holdup is proportional to the gas rate Q g.
