Abstract: In this work, the distribution of fluid field of aeration stirring type flotation machine has been simulated by computational fluid dynamics ( CFD) . The characteristics of fluid field for water phase, liquid-gas phase and solid-liquid-gas phase have been discussed, respectively. Fur-thermore, the effects of fluid field on abrasion of rotor and stator have been researched. The results could provide the guidance for improving the separation efficiency of flotation machine.
