Description

The lead bullion from Hachinohe Smelter as a major raw material and the one recovered from the secondary lead materials by smelting through a blast furnace at this Takehara Refinery are, after decopperizing and detinning at need, electro-refined together to produce electrolytic lead.<BR>The major portion of electrolytic lead is used as material for producing lead chemicals such as white lead, red lead, litharge, etc., and the rest is for sale to the customers as lead metal.<BR>Antimony is recovered as antimony trioxide by treating the lead slime obtained through electrolytic process and the residual lead is fed to the silver recovering process in the copper processing plant to recover rarious precious metals. As by-products, tin is also produced from this process and valuable metals are recovered as lead bullion from the residual lead carbonate processed through by solvent extraction.
