Devices and method for smelterless recycling of lead acid batteries

Last updated:

Abstract:

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, and spent electroprocessing solvent can be recycled to the recovery process.
