| abstract | SUMMARY OF THE INVENTION An object of the present invention is to provide a method for efficiently and efficiently recovering high-purity metal lead from lead-containing materials such as lead carbonate, lead oxide, lead hydroxide, and lead sulfate generated in metal smelting and industrial waste treatment processes. .n n n (Measures) In order to leach lead-containing materials generated in metal smelting and industrial waste treatment processes in a nitric acid solution at a condition of pH 1 to 3 and a reaction time of 1 hour or more, and after filtration to remove impurities of precious metals from lead in the filtrate. Substituent reaction is carried out in the range of pH 2-3 using metal lead, and the substituted after solution is used as a supplementary addition liquid in the lead electrolysis process of the next process after filtration, and an anode in lead electrolysis Lead oxide is deposited on the anode and metal lead on the cathode by electrolytic extraction from lead nitrate solution using either an insoluble anode for the anode and a titanium plate or a lead end plate for the cathode. After the separation, the lead dioxide is peeled off and recovered from the anode, melted and reduced together with a reducing agent to form a metal lead, and after cooling, caustic soda is added to remove the trace impurities, followed by casting Gain,n n n A method for recovering lead of high efficiency and high purity in which electrodeposited lead recovered from the cathode is also melted, followed by adding caustic soda to remove trace impurities and casting to obtain electrolytic lead.n n n n Electric Lead, Recovery |
