  • Recycle process for alkaline and carbon zinc batteries
    Patent number: 8911696
    Abstract: High purity MnO and zinc oxide may be efficiently recovered from alkaline and/or carbon zinc batteries using a process involving the treatment of the crushed batteries with an alkali hydroxide to produce insoluble manganese oxides and an alkali zincate solution. Zinc oxide is obtained by reacting the zinc solution with carbon dioxide or an acid such as a mineral acid and furnacing. The manganese oxides are converted to MnO by furnacing under an inert atmosphere.
