Abstract Scope The aeration leaching process is a three-phase reaction of gas, liquid and solid. The solid phase is black opaque particles. It is difficult to observe the flow field and the distribution of each phase. The water model experiment does not involve chemical reactions, and the physical properties of the solid particles remain unchanged. The effect of particle changes on the flow field cannot be explored. This study is based on computational fluid dynamics (CFD) software, using the Euler-Euler three-fluid model. A 60L stirred reactor was simulated, and the solid-liquid ratio in the tank was 1:4, ventilation rate Q=1~2.5m/h, speed 400~500rpm. This study simulated the particle changes in the real reaction process, and analyzed the phase distribution and flow field.
