The article presents the results of a study of the kinetics of extraction of non-ferrous metals in the form of inorganic chlorides from lead fusing slags in the presence of a distiller's liquid.It is established that the maximum degree of chloride distillation of non-ferrous metals from the fusing slag (lead by 92.2%, copper-89.2%,zinc 92.0%) is observed at a temperature of 1000 0 C for 90 minutes.It was determined that an increase in the degree of chloride distillation of copper and lead is accompanied by a decrease in the Eap for copper from 126 to 54 kJ/mol and lead from 128 to 88 kJ/mol.Chloride distillation of copper at the beginning of the process proceeds in the kinetic mode, at the end in the transition, and lead -in the kinetic model.The life span of the generation period of copper chloride distillation is 140 kJ/mol, and lead-162 kJ/mol.Zinc chloride distillation takes place in a transient mode and is characterized by Eap 58 kJ/mol.Intensification of metal chloride distillation from slags is possible due to an increase in temperature.
