Mixing and stirring is an important pre-treatment process before mineral flotation, which can clean the surface of mineral particles, create good particle suspension conditions, fully mix and contact mineral particles with flotation reagents, thereby saving reagent dosage and improving flotation indicators. Research has shown that the appropriate flow field environment and process parameters in the mixing tank play an important role in the mixing effect. In order to better study the motion law of fluid in the stirred tank and the mechanism of action between reagents and mineral particles, computational fluid dynamics (CFD) was used to numerically simulate the mixing process, and combined with experimental methods,researchers have already done a lot of scientific research work. This article provides a brief introduction to the numerical simulation technology of solid-liquid mixing involved in the slurry mixing process, reviews the research and achievements of previous researchers using CFD technology in the field of flotation slurry mixing, and prospects the research direction of CFD technology in the flotation slurry mixing process.
