Gegenstand der Erfindung bildet ein Verfahren zum Entkupfern von Antimon-Kupfer-Zinn - Bleilegierungen und kennzeichnet sich dadurch, daß die Legierung oxydiert und die erhaltenen Oxyde hierauf mit Essigsäure behandelt werden.The invention relates to a method for removing copper from antimony-copper-tin - Lead alloys and is characterized by the fact that the alloy oxidizes and the oxides obtained are then treated with acetic acid.
Es ist bereits bekannt, bei Kupfer - Silber-Blei - Schwefelverbindungen zwecks Durchführung der nassen Trennung die Ausgangslegierung oder Verbindung zu oxydieren. Desgleichen ist es bekannt, die Entkupferung auf Grund der leichten Löslichkeit des Kupferoxydes und der Schwerlöslichkeit der übrigen Metalle oder ihrer Sulfate in verdünnter Schwefelsäure auszuführen.It is already known, in the case of copper - silver-lead - sulfur compounds for the purpose of carrying out the wet separation to oxidize the starting alloy or compound. It is also known, the copper plating due to the easy solubility of the copper oxide and the poor solubility of the carry out other metals or their sulfates in dilute sulfuric acid.
Neu ist. bei vorliegendem Verfahren, daß dabei ausschließlich Metalloxyde mit Essigsäure behandelt werden und nicht, wie bei ähnlichen Verfahren, Metalle.New is. in the present process, that only metal oxides with acetic acid treated and not, as in similar processes, metals.
Die Legierungen, welche der Behandlung durch folgendes Verfahren unterworfen werden sollen, sind in der Regel wie folgt zusammengesetzt: The alloys to be subjected to the treatment by the following procedure are usually composed as follows:
30 bis 70 Prozent Zinn, 15 bis 40 Prozent Kupfer, Spur bis 3 Prozent Eisen, 10 bis 25 Prozent Antimon, 5 bis 45 Prozent Blei.30 to 70 percent tin, 15 to 40 percent copper, trace up to 3 percent iron, 10 to 25 Percent antimony, 5 to 45 percent lead.
Solche Kupferverbindungen lassen eine unmittelbare Verwendung des hohen Kupfergehaltes wegen nicht zu, auch würde die Verarbeitung auf ein isoliertes Metall, wje Kupfer oder Zinn, allein mit großen Kosten und gleichzeitig mit A^erlusten des anderen Metalls verbunden sein.Such copper compounds allow immediate use of the high copper content because of not too, the processing would also be on an insulated metal, wje Copper or tin, alone at great expense and at the same time with the loss of the other Metal.
Zwecks Ausführung des den Gegenstand der Erfindung bildenden Verfahrens werden die Legierungen in einem deutschen Treibofen oxydiert. Bei Verarbeitung bleiarmer Legierungen besteht der Herd aus Schamotte, dagegen wird bei Behandlung von Legierungen, welche sehr viel Blei enthalten, für den Herd ein Gemenge von Kalk, Ton und Zement verwendet.For the purpose of carrying out the method forming the subject of the invention the alloys are oxidized in a German blowing furnace. Less lead when processed Alloys, the hearth consists of fireclay, on the other hand, when treating alloys, which contain a lot of lead, a mixture of lime, clay and cement is used for the stove.
Die Oxydation selbst wird bei niedriger Temperatur eingeleitet und nur so hoch bemessen, daß ein Schmelzen bei kupferreichen Legierungen nicht eintritt. Die Temperatur wird erst dann erhöht, wenn bereits der größte Teil der Legierungen zerfallen ist, also ein Sintern der zu behandelnden Masse stattgefunden hat. .The oxidation itself is initiated at a low temperature and is only dimensioned as high as that melting does not occur in copper-rich alloys. The temperature is only increased when the largest part of the alloys has disintegrated, so a sintering of the mass to be treated has taken place. .
Diese Steigerung der Temperatur dient dazu, den letzten Rest vollständig einzuschmelzen, worauf die zerfallene Legierung möglichst vollkommen durchgerührt wird. Gleichzeitig läßt man den Gebläsewind auf das Metall einwirken, damit das Kupferoxydul in Kupferoxyd übergeht. Der weitere Verlauf der Oxydation wird nun so geführt, daß, falls die gewählte-Legierung nur einen geringen Bleigehalt besitzt, keine Schlackenbildung eintritt, welch letztere nur dann nicht zu vermeiden ist, wenn der Bleigehalt der Legierung den Kupfergehalt weit übersteigt. This increase in temperature serves to completely melt the last residue, whereupon the disintegrated alloy is stirred as completely as possible. At the same time the fan wind is released the metal act so that the copper oxide changes into copper oxide. The other one The course of the oxidation is now carried out in such a way that, if the selected alloy, only one has a low lead content, no slag formation occurs, the latter only then cannot be avoided if the lead content of the alloy far exceeds the copper content.
Das Einsetzen der Legierungen in den Treibofen wird so geregelt, daß der Kupfergehalt höher als der Bleigehalt oder dem Bleigehalt wenigstens annähernd gleich ist. Die Oxydation der zerfallenen Legierung geht ziemlich schnell vor sich, während das Oxydieren des eingeschmolzenen Restes der Legierung längere Zeit in Anspruch nimmt.The use of the alloys in the blowing furnace is regulated so that the copper content higher than the lead content or at least approximately equal to the lead content. The oxidation of the disintegrated alloy goes on fairly quickly while oxidizing the melted remainder of the Alloy takes a long time to complete.
Die erhaltenen Oxyde werden gemahlen und alsdann mit heißer 50 prozentiger Essigsäure behandelt; hierbei geht alles Kupfer und Blei in Lösung. Die als unlöslich zurückgebliebenen Oxyde von Zinn und Antimon werden, nachdem die Essigsäurelösung entfernt ist, in einem Flammofen auf Metall verarbeitet.The oxides obtained are ground and then treated with hot 50 percent acetic acid treated; here all copper and lead go into solution. Those left behind as insoluble Oxides of tin and antimony are removed after the acetic acid solution is processed on metal in a flame furnace.
Die essigsaure Lösung wird unter Zusatz von Schwefelsäure eingedampft und die Essigsäuredämpfe durch Verdichtung wiedergewonnen. Die hierdurch erhaltene KupfersulfatThe acetic acid solution is evaporated with the addition of sulfuric acid and the acetic acid vapors recovered by compression. The copper sulfate thus obtained
lösung läßt man kristallisieren oder fällt das Kupfer durch Eisen aus. Das durch Zusatz von Schwefelsäure ausgefällte Bleisulfat wird 15 ebenfalls im Flammofen auf Metall verarbeitet. solution is allowed to crystallize or the copper is precipitated by iron. That by addition Lead sulphate precipitated by sulfuric acid is also processed on metal in a flame furnace.
