VERFAHREN ZUR HERSTELLUNG VON BLEIMONOXID AUS BLEISULFAT MIT SAUREM AMMONIUMAZETAT

摘要

An efficient and inexpensive method for producing lead monoxide from impure lead sulfate bearing materials such as recycled battery mud is provided comprising: (a) reacting said material with an ammonium carbonate solution to convert lead sulfate to lead carbonate; (b) decomposing the lead carbonate to produce impure lead monoxide; (c) reacting said impure lead monoxide with an acidic ammonium acetate solution to form a lead acetate solution; (d) reacting ammonium hydroxide with the lead acetate solution to form lead hydroxide; and (e) dehydrating the lead hydroxide to produce lead monoxide.
