Description

Verfahren zur Aufarbeitung von verbrauchten galvanischen Elementen. Die Erfindung betrifft ein Verfahren zur Aufarbeitung verbrauchter Elemente, insbesondere der in den sogenannten Puppen verbrauchter Leclanche-Elemente enthaltenen Bestandteile Manganverbindungen, Graphit und Zink.Process for reconditioning used galvanic elements. The invention relates to a method for reconditioning used elements, in particular the constituents contained in the so-called dolls of used Leclanche elements Manganese compounds, graphite and zinc.

Zu diesem Zwecke werden diese Massen in einer geeigneten Vorrichtung, z. B. Retorte, evtl. unter Zugabe von Reduktionsstoffen zur Rotglut erhitzt. Die bei der Erhitzung entwickelten Gase und Dämpfe entweichen durch ein im Retortendeckel vorgesehenes Abzugsrohr und werden in geeigneter Weise in Vorlagen usw. aufgefangen. Die Manganoxyde werden hierbei zu Manganoxydul reduziert, während das Zink, teilweise zu Metall reduziert, auf dem Retortenboden zusammenschmilzt, teilweise durch das Abzugsrohr zusammen mit Ammoniakverbindungen dampfförmig entweicht und gewonnen wird. Nach beendeter Reaktion wird das Abzugsrohr verschlossen und somit während des Abkühlungsprozesses der Wiedereintritt von Luftsauerstoff verhindert. Es hinterbleibt eine Masse, bestehend aus oxydfreiem Manganoxydul, Graphit und ein Zinkregulus auf dem Retortenboden. Das Manganoxydul wird durch verdünnte Säure vom Graphit getrennt und das erhaltene Mangansulfat in hochoxydische Maganverbindungen übergeführt.For this purpose, these masses are placed in a suitable device, z. B. Retort, possibly heated to red heat with the addition of reducing substances. the Gases and vapors developed during heating escape through a hole in the retort lid provided exhaust pipe and are collected in a suitable manner in templates, etc. The manganese oxides are reduced to manganese oxide, while the zinc, partially reduced to metal, melts together on the bottom of the retort, partly through the Flue pipe escapes in vapor form together with ammonia compounds and is recovered will. After the reaction has ended, the exhaust pipe is closed and thus during the re-entry of atmospheric oxygen is prevented during the cooling process. It remains behind a mass consisting of oxide-free manganese oxide, graphite and a zinc regulator the retort bottom. The manganese oxide is separated from the graphite by dilute acid and the manganese sulfate obtained is converted into highly oxidic maganic compounds.

Durch vollkommene Überführung der Manganoxyde in Manganoxydul und Verhinderung seiner Wiederoxydation gelingt es, das in verdünnten Säuren leicht lösliche Magansulfat quantitativ wiederzugewinnen und die Gesamtmenge desselben für höchoxydische Manganverbindungen nutzbar zu machen.By complete conversion of the manganese oxides into manganese oxide and It is easy to prevent its reoxidation in dilute acids Quantitatively recover soluble magnesium sulfate and the total amount of the same to make it usable for highly oxidic manganese compounds.
