A bubble-particle interaction model for flotation combining hydrodynamic and surface forces
It is generally recognized that the recovery of particles from a flotation pulp is controlled by (i) the flotation rate constant and (ii) the residence time distribution of the particles. In the present work, theoretical and experimental analyses have been carried out to develop methods for …

Validation and Application of a First Principle Flotation Model
… from the basic mechanisms involved in the bubble-particle and bubble-bubble interactions occurring in flotation. It is a kinetic model based on the premise that the energy barrier (E1) for bubble-particle interaction can be reduced by increasing the kinetic energy (Ek) for bubble-particle …

Application of Extended DLVO Theory: Modeling of Flotation and Hydrophobicity of Dodecane
… energies for thinning the water films between bubbles and particles, which were compared with the energy barriers, created by surface forces, to determine the probability of adhesion. A general expression for the probability of detachment was derived from similar mechanism for chemical …

Experimental Study of Multi-phase Flow Hydrodynamics in Stirring Tanks
… Flotation refers to the process in which air bubbles selectively pick up hydrophobic particles and separate them from hydrophilic solids. This technology is used throughout the mining industry as well as the chemical and petroleum industries. In this research, efforts were made to investigate …

Water quality effects on the bubble-particle attachment of sulfide minerals
probability, mass of particles recovered in the ACTA and further validation with microflotation recovery that bubble-particle interaction increases as the ionic strength of the plant water increases. This was the case with both chalcopyrite and galena particles. Literature would suggest that this …
