  Gas dispersion measurements in flotation cells - ScienceDirect

  20071019 · Gas dispersion is the collective term for superficial gas (air) velocity (or gas rate, volumetric air flow rate per unit cross-sectional area of cell, Jg ), gas-holdup (volumetric fraction of gas in a gas–slurry mix, εg ), and bubble size distribution ( Db ). The sensors and devices we have used to measure these variables in flotation ...

  CDF simulation of bubble-particle collisions in mineral flotation cells ...

  2000121 · Abstract. The efficiency of the flotation process depends highly on the initial contact between the air bubble and the mineral particle. To enhance this contact, flotation cells are designed to achieve good mixing between the suspending solids and the dispersing air. CFD simulation of flotation cells provides an opportunity to analyse the ...

  Mixing and gas dispersion in mineral flotation cells

  2008121 · Mineral flotation in mechanically agitated vessels (cells) involves complex interaction between bubbles, particles and the liquid phase. Ideally, just enough power input from the impeller is needed to so that the frequency of particle–bubble collision and attachment is maximised, while at the same time detachment events are minimised.

  Modelling of froth transportation in industrial flotation cells

  200491 · Modelling of froth transportation, as part of modelling of froth recovery, provides a scale-up procedure for flotation cell design. It can also assist in improving control of flotation operation. Mathematical models of froth velocity on the surface and froth residence time distribution in a cylindrical tank flotation cell are proposed, based on mass …
