Abstract The physical variables that influence the rate of flotation are examined The probabilistic model of flotation is used to establish the effect of the particle si2e and density bubble size and agitation on the rate of flotation In quiescent flotation it appears that the flotation rate is limited by the particlebubble collision and subsequent attachment of the particle to the bubble
