Mixer-settlers typically contain an impeller mounted on a shaft, and optionally it can contain baffles. In this study, the effect of the number of baffles on the separation characteristics of the system, and the effect of blade width and inlet velocity on baffles number have been investigated. Computational Fluid Dynamics (CFD) model is developed to predict the separation characteristics. The model has been validated with the help of experimental data for different velocity outlet used in the work. This work has enabled developing efficiency that can produce higher condition than those reported in the previous literature.
