    Jan 01, 1992 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.
