METHOD OF SEPARATION AND EXTRACTION OF METALS AND SYSTEM FOR SEPARATION AND EXTRACTION OF METALS Russian patent published in 2016 - IPC C25C3/26 C25C7/06 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to electrolytic separation and extraction of metals from mixture of metals in molten salts. Mixture of metals comprises, at least, first metal and second metal, second metal has higher standard electrode potential than first metal. Method includes connecting said mixture of metals with anode in molten salts, first step for electrolysis of first metal with first metal deposition on cathode, step for detection of low concentration of ions of first metal in molten salts using detection unit of change of concentration, first stage of extraction of deposited substance in accordance with detection at stage of detecting, on which is determined by reduction of first metal ion concentration, using previously specified in unit for detecting change in concentration, second step for electrolysis of second metal with second metal deposition on cathode, step for detection of low concentration of ions of metal in molten salts using detection of change of concentration unit and second stage of extraction of deposited substance.

EFFECT: also disclosed is system for implementation of this method, comprising unit for detecting change in concentration of metal ions.
