New directions in flotation machine design
To use the Smoluchowski equation, we need an estimate of the number concentration N b of bubbles in the flotation cell, which is related to the gas holdup. 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.

Improving flotation energy efficiency by optimizing cell hydrodynamics
In conventional flotation cells a certain amount of energy is required to meet the basic requirements for flotation (air dispersion, solids suspension and particle-bubble collision). This paper investigates how that energy is dissipated in the flotation cell to determine the most efficient use of the imparted energy.
