VERFAHREN ZUR AUFARBEITUNG VON KLEIN-BATTERIEN

摘要

After being mechanically destroyed, miniature batteries are roasted with the addition of a lean material and solid chloride at temperatures of 580 to 700 DEG C. The volatile mercury is washed out of the exhaust gas. The roasted product is leached with an aqueous solution containing dilute hydrochloric acid. Base metals are precipitated from the solution by the addition of zinc. The solution containing the zinc, and the precipitate containing the base metal are processed.
