Description

Verfahren zum Aufschluß von eisenreichen Metallegierungen. Es ist bekannt, daß in Gegenwart von Salzlösungen des Chlormagnesiums das Eisen der Dampfkessel durch Sauerstoff stärker angegriffen wird als in der reinen: Wassers. Nun wurde ,gefunden, daß auch schon bei gewöhnlicher Temperatur die Reaktion zwischen Sauerstoff und Eisen und auch anderen Metallen in Gegenwart geeigneter Salzlösungen sehr lebhaft verläuft, womit ein Weg gegeben ist, Metalle, Legierungen und Zwischen- wie Abfallprodukte der Hüttenindustrie mit geringstem Kostenaufwand dem feuchten Aufschluß zu unterziehen.Process for the digestion of iron-rich metal alloys. It is known that in the presence of salt solutions of magnesium chloride the iron of the steam boiler is more strongly attacked by oxygen than in pure: water. Well was , found that even at ordinary temperature the reaction between oxygen and iron and also other metals very vividly in the presence of suitable salt solutions runs, with which a way is given, metals, alloys and intermediate and waste products to subject the metallurgical industry to the wet digestion at the lowest possible cost.

Der Verwextung der Ofensauen, die oft erhebliche Mengen seltener Metalle enthalten, standen bisher die hohen Kosten für Reagenzien und der unverhältnismäßig große Arbeitsaufwand, den die Aufschließung der großen Eisenmassen bedingt, aus denen die Ofensauen im wesentlichen bestehen, entgegen.The Verwextung the furnace sows, which often contain significant amounts of rare metals included, the high cost of reagents and the disproportionate the great amount of work involved in breaking down the large iron masses against which the oven sows essentially exist.

Nach der vorliegenden Erfindung ist es leicht möglich, das Eisen in Eisenhydroxyd zu verwandeln, indem man Luft durch das einigermaßen kleingebrochene, mit einer etwa toprozentigen Bittersatzlösung bedeckte Material leitet. Die Absorption des Sauerstoffes ist so lebhaft, daß ein erheblicher Teil desselben schon von ziemlich niedrigen Schichten des Reaktionsgemisches festgehalten wird, so daß die aufzuwendende Luftmenge sehr gerixg bemessen werden kann. Man erhält das Eisen in Form eines leicht abschlämmbaren Eisemhydroxydschlammes, während die Fremdmetalle, von denen nur wenig in Lösung geht, in dem schweren Rückstand angereichert sind.According to the present invention, it is easily possible to use the iron in To transform iron hydroxide by letting air through the material covered with an approximately 100% bitter substitute solution conducts. The absorption the oxygen is so lively that a considerable part of it is already quite low layers of the reaction mixture is held, so that the expended Air volume can be measured very gerixg. The iron is obtained in the form of an easy Elutable Eisemhydroxydschlammes, while the foreign metals, of which only a little goes into solution, in the heavy residue are enriched.

Der Aufwand für Reagenzien ist dadurch besonders gering, daß man die verschiedensten Abwässer der Solofabriken, Kaliwerke, Salinen u. a., die zuni Teil ohne weiteres oder nach entsprechender Verdünnung brauchbar sind, für das Verfahren verwenden kann.The effort for reagents is particularly low in that you have the various wastewater from solo factories, potash works, salt pans, etc., which are initially part are readily usable for the process or after appropriate dilution can use.

Auch Meerwasser, nötigenfalls durch Konzentration, Zugabe von Salzen oder den obenerwähnten Fabrikabwässern an Salzen angereichert, kann zum Aufschluß benutzt werden.Also sea water, if necessary by concentration, addition of salts or the abovementioned factory wastewater enriched in salts, can be used for digestion to be used.

Es zeigte sich, daß aus Kupfer enthaltenden Eisenlegierungen durch das Verfahren nach vorliegender Erfindung das Kupfer gelöst wird, besonders leicht, wenn die Salzlösungen Chloride enthalten. Aus den Lösungen kann nach Abtrennung des Eisenhydroxydschlammes das Kupfer in bekannter Weise gewonnen werden.It was found that iron alloys containing copper by the method according to the present invention, the copper is dissolved particularly easily, if the salt solutions contain chlorides. From the solutions can after separation of the iron hydroxide sludge, the copper can be obtained in a known manner.
