    Introduction. The last 10 years have seen significant advances in the measurement of so-called gas dispersion properties in flotation machines, namely: gas superficial velocity (or simply gas rate) (J g), gas holdup (ε g) and bubble size (diameter, D b).From these can be derived the bubble surface area flux (S b = 6J g /D b, where D b is usually the Sauter mean diameter, D 32).

  • Modeling the Sauter Mean Bubble Diameter in Mechanical

    There currently exists no available model for predicting the Sauter mean bubble diameter, D32, from the key process variables for mechanical flotation machines. This is seen as a significant shortcoming since flotation is a surface area (of bubbles) dependent process, the key metric being the bubble surface area flux, Sb, defined as 6 Jg/ D32, where Jg is the superficial gas velocity.

  • The distribution of air bubble size in the pneumo

    The flotation rate constant is the value characterizing the kinetics of cyclic flotation. In the statistical theory of flotation its value is the function of probabilities of collision, adhesion and detachment of particle from the air bubble. The particle air bubble collision plays a key role since there must be a prior collision before the particle air bubble adhesion happens.

  • New directions in flotation machine design ScienceDirect

    2010-10-1 · 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.
