The hydrodynamics of an operating flash flotation cell ...

2013-2-1  The data presented here is intended to form the foundations of more thorough analysis of an operating flash flotation cell and also provide the basis on which the lead author will develop a phenomenological model of the flash flotation cell under consideration. As this is a complex task, this model will be presented in a separate, subsequent paper.

Key parameters for evaluating the hydrodynamic conditions within an operating flash flotation cell have been investigated. Profiles of the slurry at increasing depth within the cell have shown a strong trend of increasing slurry density (per cent solids) and coarseness (P 80), with a clear indication of segregation on the basis of particle specific gravity.
