  • Modeling of Coal Flotation in a Batch and Continuous …

    Detailed kinetic analyses of various size fractions of coal in a batch and continuous flotation operation have been presented. It is shown that the recoveries of non-ash and ash forming materials of individual size fractions during flotation in both batch and continuous cells can be described adequately by first order kinetic equations. A methodology has been proposed to predict the kinetic ...

  • Batch cell flotation models — A review

     · Batch cell flotation models are critically reviewed in detail with respect to their suitability for genuine prediction of batch cell behaviour. There is ample evidence in the literature that particle-bubble attachment in the flotation cell pulp is fundamentally a first order kinetics process if the heterogeneous flotation behaviour of mineral particles is accounted for.

  • Simulation of flotation plants

     · In a flotation plant flowsheet simulator, each cell is operated with continuous recovery models using the same batch test based kinetic mineral parameters, but adjusted with a scale up factor. The scale up factor is a ratio of the required plant time compared to the laboratory time to achieve the same target recovery.
