There is a large body of literature that tries to model flotation based on froth properties with little or no experimental verification of the underlying features. These models adopt the so called channel-dominated theory of foam drainage. There is no experimental evidence to support this foam drainage theory. Instead the new, simple and experimentally validated foam drainage equation of Stevenson (2006a) {[Stevenson,} P. 2006a. Dimensional analysis of foam drainage. Chem. Eng. Sci. 61, 4503-4510] has been extended to describe the liquid flux and liquid profile in columns of pneumatic froth. The condition for the maximum value of gas rate for froth stability has been described and this shows that there is a maximum volumetric liquid fraction that a foam can exhibit. It is shown that the numerical calculations of liquid profile of Neethling et al. (2003a,b) {[Neethling,} {S.J.,} Lee, {H.T.,} Cilliers, {J.J.} 2003a. The recovery of liquid from flowing foams. J. Phys.: Cond. Matter 15, 1563-1576; Neethling, {S.J.,} Lee, {H.T.,} Cilliers, {J.J.} 2003b. Simple relationships for predicting the recovery of liquid from flowing foams and froths. Miner. Eng. 16, 1123-1130] are incorrect, and this may mean that all of their later simulations of the flotation process are similarly deficient. Instead a simple and accessible method of calculated liquid fraction profiles, both with and without added washwater is shown. In addition, a model for the effect of surface and internal bubble coalescence on the hydrodynamic condition of the froth is presented. It is recognised that the gas-liquid systems considered in the current work are dissimilar to practical mineralised flotation froths and these differences are discussed.},

The Reflux Classifier has an enhanced hydraulic capacity due to the presence of parallel inclined plates, which provide for a larger effective sedimentation area. This paper describes the first detailed study of the continuous steady-state size classification achieved by the device under well-controlled laboratory conditions. Separations of silica were performed at typically 160 [mu]m. Following a series of preliminary size classification experiments, an innovative fluidization arrangement was introduced which resulted in a significant improvement in the separation efficiency to levels higher than previously reported using conventional fluidized bed separators. In turn, remarkably high feed solids loadings were used, with satisfactory separations produced using a feed solids throughput in excess of 5.1 kg/m2 s, which appears to be about three times higher than the highest reported throughputs for this separation size.},

	abstract = {
The hydrodynamic transport of particles of different densities along inclined channels was examined using the reflux classifier {(RC),} a novel system consisting of a set of parallel inclined plates above a fluidized bed. Fluidization water is passed through the base of the vessel, suspending the system of particles, in turn entraining the particles through a set of inclined channels. Sand, ilmenite and polyvinyl chloride {(PVC)} particles were used in separate investigations. Faster settling particles tended to deposit onto the inclined surfaces and slide back down, and hence return to the fluidized bed. Slower settling particles remained suspended and hence reported with the overflow water. Over time, a semi-batch separation was achieved and a partition curve produced. A generalized empirical relationship which takes into account the superficial fluidization velocity, aspect ratio of the channels, angle of inclination of the channels and particle Reynolds number was developed in order to describe the broad range of experimental data. The relationship should prove useful in predicting the separations from the {RC} under specific conditions and the likely throughput advantage of the {RC} over a conventional fluidized bed. The asymptotic form of the relationship, obtained for an infinite channel aspect ratio, provides a description relevant to hydraulic conveying, especially in the area of directional drilling in which particles are conveyed up the inclines. This relationship also indicates the strong potential for separating particles on the basis of density, with the analysis indicating no particle size dependence when the particle Reynolds number is relatively high.},
