The paper presents the results of electroleaching of lead and zinc by an electrochemical method from mineral raw materials using a sulfurgraphite electrode as a cathode. Extraction of metals from the hardly refractory sulfide intermediate product requires a change in technological conditions in accordance with the structure and physicochemical state of compounds containing the base metal. The result of x-ray phase analysis showed that the metals contained in the mineral raw materials are in the form of sulfides. The initial concentration of sodium hydroxide during leaching in solutions of 0.1 M and 0.5 M. The duration of the electrochemical leaching was 5 hours. The maximum extraction during leaching of the concentrate for zinc is 42.15% and for lead 61.65% in 5 hours. A brief description of the mineral raw materials used in the Shalkiya deposit is given. It has been established that the use of a sulfurgraphite electrode as a cathode has a positive effect in the electrochemical leaching of lead and zinc from the concentrate.
