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. Spent electroprocessing solvent and/or base utilized to treat lead paste from the lead acid battery scrap can be recycled to the recovery process.

Abstract translation: 来自铅酸蓄电池废料的铅在两个单独的生产流中被回收，作为干净的电网引线和高纯度铅而不进行冶炼。 在优选的方面，铅回收在使用水性电处理溶剂的连续方法中进行，并且电精炼和废电加工溶剂可以再循环到回收过程中。
