Particle-bubble sub-processes cannot be directly and physically obtained in froth flotation due to the complexity of the process as well as numerous and dynamic interactions of particles and bubbles in an extremely intensive turbulent condition. Therefore, over the last three decades, two fundamental model configurations have been used as an only solution for prediction of particle-bubble collection efficiencies (E-coll). Additionally, the relative intensity of the main flotation parameters on flotation rate constant, particle-bubble interactions together with their interrelations is not adequately addressed in the literature.
