Verfahren zur Entzinkung des Bleies. Patentiert im Deutschen Reiche vom 24. Mai 1910 ab.Process for dezincification of lead. Patented in the German Empire on May 24, 1910.
Bei verschiedenen Hüttenprozessen, z. B. beim Entsilbern des Bleies mittels Zinks, bleibt eine geringe Menge des Zinks im Blei zurück. Die Entfernung des Zinkgehaltes aus solchem Blei geschah bis jetzt durch Durchleiten von Wasserdampf, wobei sich neben dem Zinkoxyd auch größere Mengen sogenannter Dampfglätte bildeten, welche mit dem Zinkoxyd vermischt waren und eine neue Reduktion bzw. Trennung erforderten. Außerdem entstand hierbei stets ein größerer Verlust an Zink.In various metallurgical processes, e.g. B. when desilvering the lead by means of zinc remains back a small amount of the zinc in the lead. The removal of the zinc content from such Up to now, lead has been done by passing water vapor through it, which is next to the zinc oxide larger amounts of so-called steam smoothness were also formed, which were mixed with the zinc oxide, and a new reduction or separation required. In addition, there was always a greater loss Zinc.
Der Gegenstand der Erfindung ist ein Verfahren, welches diese Übelstände vermeidet.The subject of the invention is a method which avoids these inconveniences.
Es besteht darin, daß dem zu entzinkenden geschmolzenen Blei Zinkchlorid und eine entsprechende geringe Menge Bleioxyd, Bleiasche o. dgl. zugesetzt wird. Nach kurzem Umrühren der Masse hat das im Blei vorhandene Zink eine äquivalente Menge von Blei aus dem Bleioxyd reduziert und ist selbst zu Oxyd umgewandelt worden. Die hierbei stattfindenden Reaktionen sind vermutlich folgende:It consists in the fact that the molten lead to be dezincified is zinc chloride and a corresponding A small amount of lead oxide, lead ash or the like is added. After briefly stirring the mass, what is present in the lead has Zinc reduces an equivalent amount of lead from the lead oxide and is itself too Oxide has been converted. The reactions that take place are probably the following:
Zn + PbO + Zn Cl2 = Zn + PbCl2 + Zn O, Zn + Pb Cl2 + ZnO ^ Zn Cl2 + Pb + Zn O. Zn + PbO + Zn Cl 2 = Zn + PbCl 2 + Zn O, Zn + Pb Cl 2 + ZnO ^ Zn Cl 2 + Pb + Zn O.
Statt des Zinkchlorids kann auch irgendein Doppelsalz desselben verwendet werden.Instead of the zinc chloride, any double salt thereof can also be used.
Das Verfahren wird beispielsweise in folgender Art ausgeführt. Man schmilzt 25 bis . 30 Tonnen Blei, welches etwa 1Z2 Prozent Zink enthält, unter Zusatz von 50 kg eines Doppelsalzes, welches je zur Hälfte aus Zinkchlorid und Chlornatrium besteht. Hierauf werden etwa 500 kg Bleiasche, die selbstverständlich silber- und kupferfrei seih muß, zugegeben.The method is carried out in the following manner, for example. One melts 25 to. 30 tons of lead, which contains about 1 Z 2 percent zinc, with the addition of 50 kg of a double salt, half of which consists of zinc chloride and sodium chloride. About 500 kg of lead glass, which of course must be free of silver and copper, are then added.
Statt der Bleiasche können auch silber- und kupferfreie oxydische oder sulfidische Bleierze verwendet werden, und zwar in solcher Menge, daß ihr Bleigehalt mindestens dem Zinkgehalt des zu reinigenden Metalles äquivalent ist. Das Doppelsalz kann immer wieder verwendet werden, es muß nur von Zeit zu Zeit gelöst, von dem aus Zinkoxydoder Sulfid bestehenden Rückstand ab filtriert und eingedampft werden.Instead of the lead bowl, you can also use oxydic or sulfidic silver- and copper-free Lead ores are used, in such an amount that their lead content is at least is equivalent to the zinc content of the metal to be cleaned. The double salt can always re-used, it just needs to be removed from time to time, from which zinc oxide or Sulphide existing residue is filtered off and evaporated.
Das Verfahren kann auch zweckmäßig zur Entzinkung des Zink - Silber - Schaumes gebraucht werden, welcher ebenfalls beim Entsilbern des Bleies entsteht und außer Blei 10 bis 25 Prozent Zink und 0,5 bis 5 Prozent Silber enthält.The process can also expediently be used for dezincification of the zinc-silver foam which is also produced when the lead is desilvered and, apart from lead, 10 to 25 percent zinc and 0.5 to 5 percent Contains silver.
Es ist zwar bekannt, Blei mit Hilfe von Oxydationsmitteln oder Chloratiönsmitteln oder einem Gemisch von beiden zu raffinieren. Als solche Mittel wurden vorgeschlagen: Salpeter, Bleisulfat und Chloride des Kaliums, Natriums, Magnesiums und Bleies, also ausschließlich Körper oder Gemische von sehr hohen Schmelzpunkten. Das vorliegende Verfahren läßt sich schon bei niederer Temperatur ausführen, etwa bei 400°, da das im Überschuß angewandte Chlorzink als Flußmittel wirkt. Es kann daher das vorliegende Verfahren in bekannter Weise im Schmelzkessel ausgeführt werden und sich auf diese Weise organisch an das vorgehende Entsilbern des Bleies anschließen, welches bekanntlich ebenfalls in Schmelzkesseln ausgeführt wird.It is known to use oxidizing agents or chlorination agents or lead to refine a mixture of both. As such remedies have been suggested: saltpetre, Lead sulfate and chlorides of potassium, sodium, magnesium and lead, so exclusive Solids or mixtures of very high melting points. The present process can be carried out at a low temperature run, around 400 °, because the zinc chloride used in excess as a flux works. The present process can therefore be carried out in a known manner in the melting kettle and in this way organically adhere to the preceding desilvering of the lead, which is also known to be carried out in melting tanks.
Der Gegenstand der vorliegenden Erfindung bietet daher den Vorteil des bequemeren Arbeitens, und es werden die mit der Benutzung von öfen unvermeidlichen Metallverluste vermieden. Außerdem finden bei diesem Verfahren die ohnehin in jeder Hütte vorhandenen Bleioxyde Verwendung, welche hierbei reduziert werden, ohne daß diese Reduktion besondere Kosten verursacht, während die zu älteren Verfahren notwendigen Bleiverbindungen, wie Sulfat oder Chlorid, besonders hergestellt werden mußten.The object of the present invention therefore offers the advantage of more convenient work, and the inevitable metal losses with the use of furnaces are avoided. In addition, the lead oxides already present in every hut are used in this process can be reduced without this reduction causing particular costs, while the too lead compounds, such as sulphate or chloride, necessary for older processes had to be.
