Batch cell flotation models — A review ScienceDirect

1992-1-1  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.
