FIELD: purification and desalting of highly mineralized water with element- by-element separation of products of purification. SUBSTANCE: method for desalting and purification of highly mineralized mine water includes stage electrochemical treatment in pulse magnetic field with step increase of frequency and decrease of amplitude of pulses from stage to stage. Current density at each stage of electrochemical treatment is established equal to (1-1,4)qi, where qi is specific electrode potential of one of elements with single concentration. Concentration of initial product at inlet of closed system is brought to preset value. Electrochemical treatment is carried out from element with maximum electrode potential to element with minimum electrode potential. Filtrate of the last stage is fed to inlet of closed system of stage treatment. EFFECT: higher efficiency. 3 cl, 1 dwg
