ABSTRACT:
In connection with the recycling of lead-acid batteries, lead-acid battery mud containing lead sulfate is desulfated by adding to the battery mud, which is maintained at a temperature less than 140.degree. F., an aqueous solution containing an ammonium reagent such as ammonium carbonate or ammonium bicarbonate. The ammonium reagent reacts with the lead sulfate to form an aqueous solution of ammonium sulfate and a lead carbonate precipitate. The aqueous solution of ammonium sulfate is then separated from the battery mud containing the lead carbonate precipitate.
