Abstract An unsteady solute dispersion technique was used to characterise dispersion in a baffled flotation column. The practicality of the baffle shapes and spacings was tested using a synthetic ore comprised of uniform glass beads made suitably hydrophobic by treatment with silicone oil. A particular baffle shape (convex underside) produced significant reductions in experimental axial dispersion coefficients averaging 1000 cm2/min for superficial gas velocities ranging from 23 to 85 cm/min when compared with the unbaffled column. Steady-state experiments using a synthetic ore and modelled by a linear capture mechanism produced dispersion coefficients comparable with values obtained by unsteady solute dispersion tests.
