Numerical investigation of separation of metals by non-steady-state cyclic counter-current liquid-liquid extraction

Using the extraction of chlorides of Cu, Ni, Zn, Fe as the model system, we report our numerical studies on metal separation by the method of non-steady-state cyclic (dynamic) counter-current liquid-liquid extraction. The experimental data on distribution of chlorides of Cu, Ni, Zn, and Fe in the binary extractant system were used for simulation of separation processes of metals. Numerical studies on the dynamic counter-current extraction have shown that with increasing sample loading time the separation of metals decreases, whereas with increasing number of extraction stages fewer cycles are required for metal separation.
