Flotation as a kinetic and thermodynamic phenomenon is a random process. The random variable determining the number of particles in flotation, attached permanently to the bubble surface, and consequently also the recovery, depend on time. Numerous models of flotation kinetics have been worked out to describe this dependence. Each of these models covers in fact a separate
