摘要:
Lead from lead acid battery scrap is recovered in two separate production streams as clean grid lead and as high-purity lead without smelting. In preferred aspects, lead recovery is performed in a continuous process that uses an aqueous electroprocessing solvent and electro-refining. Spent electroprocessing solvent and/or base utilized to treat lead paste from the lead acid battery scrap can be recycled to the recovery process.
