摘要

An attempt of analytical determination of selectivity criterion for separation of organic and aqueous phases in froth floatation extraction process has been made. An equation describing the criterion in question has been derived both by thermodynamic method (on the basis of application of law of active masses) and by kinetic method. With consideration of obtained experimental data, two forms of selectivity criterion for separation of phases are proposed for conditions of starting aqueous solution volume stability and instability, respectively. Also, a principal possibility of application of thermodynamic methods (employed with respect to chemical equilibrium in true solutions) for equilibrium processes running in colloidal systems is shown.
