FIELD: metallurgy.
SUBSTANCE: invention relates to the method of lead utilisation. Method of lead utilisation from waste accumulators includes location of undisturved lead plates with active mass of waste accumulator in electrolyte. Then it is implemented simultaneous dissolving of undisturved lead plates with active mass in electrolyte and lead electrochemical isolation. Additionally lead isolation is implemented at current density 5-15 mA/cm2. In the capacity of electrolyte it is used maleic acid.
EFFECT: providing of almost total lead utilisation from waste lead accumulators.
