C.D. Smith, Auteur ; K. Hadler, Auteur ; J. J. Cilliers, Auteur |Recent studies have shown that varying the distribution of a set volume of air to a flotation bank significantly affects the performance of the bank. To date, however, the volume of air to be distributed has usually been arbitrarily set as that [...]

K.E. Cole, Auteur ; G.D.M. Morris, Auteur ; J. J. Cilliers, Auteur |The stability of the thin films found in the froth phase of flotation plays an important role in the overall efficiency of the separation process. In turn, the physical behaviour of the particles attached to the films has a direct impact on the [...]

K. Hadler, Auteur ; C.D. Smith, Auteur ; J. J. Cilliers, Auteur |In recent years, developments in control strategy for banks of flotation cells have included process control based on mass pull. Mass pull, or the flowrate of solids reporting to the concentrate, is affected by changes in froth structure and sta[...]

G. Morris, Auteur ; S.J. Neethling, Auteur ; J. J. Cilliers, Auteur |A three-dimensional model of a single cubic particle in a thin liquid film has been developed using the Surface Evolver (Brakke, 1992) program. It has been used to investigate the effect of a particle’s contact angle on its energetically stable [...]

K. Hadler, Auteur ; J. J. Cilliers, Auteur |Air recovery, or the fraction of air entering a cell that overflows the cell lip as unburst bubbles, is an important measure of froth stability as it affects the flow of bubble surface to the concentrate. An experimental campaign was carried out[...]
