A possibility of application of the calculation program for numerical researches and modeling of metal separation by the combined method of liquid chromatography and counter-current extraction (dynamic counter-current extraction) has been examined. The experimental data on the distribution of chlorides of platinum metals from 2 M HCl solutions with methyltrioctylammonium dinonylnaphthalene sulphonate in toluene were used for calculation researches and simulation of separation processes of metals. Numerical studies on the dynamic counter-current extraction have shown that with increasing values of dimensionless sample loading time the separation of metals decreases, whereas with increasing number of extraction stages fewer cycles are required for metal separation. In the last case, increase in yield and purity of the separated metals is observed.
