Abstract
Chigirishima Refinery of Toho Zinc Co., Ltd., started its lead smelting and refining operation in 1951 and now produces 95,000 tons of electrolytic lead per annum. At Chigirishima Refinery, the conventional smelting and refining method was adopted, with a series of process of sintering—blast furnace—electrolytic process. We recover some valuable by-product metals such as silver from lead concentrate and also utilize the cupola furnace to recycle the lead electrode in the waste battery. This paper describes the influences of minor elements in the lead electrode treatment such as Sb, Ca, Sn, sulfuric acid, and organic substances with its measures against them.
