This study presents the modelling of zinc extraction facilitated by emulsion liquid membrane (ELM). The previously developed model was extended and modified in accordance with the present research objectives and scope. The modified model is based on the chemical interaction between the carrier molecules and zinc ions, as well as the mass transport mechanism. Furthermore, the model also accounts for the effect of Sauter mean diameter on the extraction efficiency. MATLAB was applied to simulate the ELM extraction of zinc based on the validated model. At the optimum conditions, MATLAB simulation produced a similar outcome to the one obtained experimentally. Using the validated model, several parametric studies were conducted, such as the treat ratio, initial zinc concentration, carrier concentration, and stripping agent concentration. The consistent results between the experimental and simulated data increased the reliability of the model as a viable prediction tool for zinc extraction using facilitated ELM.
