  • Process for the recovery of lead from scrapped lead batteries
    Patent number: 4107007
    Abstract: A process for the recovery of lead from scrapped lead batteries includes mechanically comminuting them and freeing them from battery acid. Then the battery scrap is treated with an alkaline reagent solution to convert lead oxide and sulphate to dissolved lead compounds, pure lead is recovered by electrolyzing the solution, and metallic lead components of the scrap are recovered by a physical separation from the scrap remaining after the dissolution treatment.
