"Hydrodynamic interactions of bubbles and particles in flotation process"@en . "Hydrodynamic interactions between bubbles and solid particles play a crucial role in many technological processes. An important industrial application is the flotation process. Flotation is a separation methods based on the ability of fine solids dispersed in a liquid to stick on the bubble surface and produce aggloinerates. These light agglomerates rise to the surface where \u00EDt is easy to separate them from the bulk of liquid. Due to the high separation efficiency, low operational cost and relative operational simplicity, flotation is frequently u\u0161ed in many areas. To comprehend the phys\u00EDco-chemical basis of the flotation phenomenon, we need f\u00EDrst to understand the individua! processes involved, e.g. particle-bubble collision, bubble deformation, particle adhesion, etc. The goal of this project is the inves\u00EDigation of the interactions between solids and bubbles in the flotation process.
