The performance of a continuous-flow stirred tank hydrometallurgical extractor has been simulated. Two models are used for such simulations: a noninteraction model based on macroscopic material balances and an interaction model featuring a stochastic treatment of the microscopic hydrodynamics of the dispersion. The models incorporate equilibrium and intrinsic kinetic expressions pertaining to a chemical system of hydrometallurgical interest: iron(III) sulfate-5-alkenyl-8-hydroxyquinoline/ xylene. Comparison between the model predictions and the experimental results indicates the interaction model to be more accurate than the noninteraction model. However, the computationally simple noninteraction model can be used to obtain first approximation to extractor performance, especially when interdro performance, especially when interdrop mixing effects are not important.
