Abstract：In order to study the influence of the operating parameters of the centrifugal concentrator on the beneficiation effect, the dynamic analysis of mineral particles in different regions in the process of centrifugal separation was researched.The main factors affecting the settlement of mineral particles were the rotational speed of the conical cone, the flow rate of the reverse water, the flow rate and the concentration of the ore. The centrifugal dressing process was numerically simulated by Fluent, and the influence of operation parameters of centrifugal concentrator on the mass deposition rate was analyzed. The reliability of simulation results and the accuracy of the best operation parameters were further verified by experiments. The results show that the mass deposition rate increases first and then decreases with the increase of the rotating speed of the conical cone, the flow rate of the reverse water, the flow rate and the concentration of the ore supply. When the rotating speed is710 r/min, the flow rate is 68 L/min, the flow rate is 0.66 m³/h and the concentration is 20%, the beneficiation effect is the best.
