Die Erfindung bezieht sich auf ein Verfahren zur Verarbeitung von Anodenschlamm der elektrolytischen Bleireinigung und besteht darin, daß der Schlamm mit Oxydationsmitteln behandelt wird, welche die darin enthaltenen Metalle zu oxydieren vermögen, wobei gleichzeitig für Lösung der Öxydationserzeugnisse von Kupfer, Arsen usw. Sorge getragen wird unter Belassung der Haupt-The invention relates to a method for processing anode sludge electrolytic lead cleaning and consists in that the sludge with oxidizing agents is treated, which are able to oxidize the metals contained therein, wherein at the same time care for the solution of the oxidation products of copper, arsenic, etc. is worn leaving the main
to masse des Antimons als Oxyd, Hydroxyd usw. in ungelöstem Zustande. Auf diese Weise wird eine Trennung des Antimons von dem im Schlamm enthaltenen Kupfer und Arsen erzielt. Die Abscheidung des Antimons von der durch Schmelzung auf Silber und Gold zu verarbeitenden Restmasse des Schlammes kann nach der Abscheidung von Kupfer und Arsen beispielsweise durch Behandlung mit einem Lösungsmittel, etwa Flußsäure, für das gebildete Antimonoxyd und etwaige sonstige vorhandene Antimonverbindungen erfolgen.to mass of antimony as oxide, hydroxide, etc., in an undissolved state. To this A separation of the antimony from the copper and arsenic contained in the sludge is achieved in this way. The deposition of the Antimony from the residual mass to be processed by melting on silver and gold the sludge can after the separation of copper and arsenic, for example Treatment with a solvent, such as hydrofluoric acid, for the antimony oxide formed and any other existing antimony compounds.
Als besonders geeignetes Oxydationsmittel für die in dem Schlamm enthaltenen Metalle empfiehlt sich Ferrisulfat (Fe2(SOJ3), daA particularly suitable oxidizing agent for the metals contained in the sludge is ferric sulfate (Fe 2 (SOJ 3 ), since
Cu + Fe2 Cu + Fe 2
= Cu = Cu
dieser Stoff nicht nur die Eigenschaft hat, die in Betracht kommenden Metalle, Arsen, Kupfer und Antimon, zu oxydieren, sondern da dessen sich hierbei ergebendes Reduktionserzeugnis durch Elektrolyse wiedert oxydiert werden kann, ohne daß einer der Bestandteile in Gasform verloren geht. this substance not only has the property of containing the metals, arsenic, Copper and antimony, but since the resulting reduction product is oxidized again by electrolysis can be without any of the components being lost in gaseous form.
Die Ausführung des neuen Verfahrens ge- 4^ staltet sich zweckmäßig wie folgt:The execution of the new process overall 4 ^ to staltet appropriate as follows:
Der Schlamm wird in einem Behälter, welcher mit Blei ausgekleidet sein kann, zusammen mit einer heißen Lösung von Ferrisulfat umgerührt, wobei die letztere etwa 2 Prozent freie Schwefelsäure und 4 Prozent Ferrisulfat enthalten kann.The sludge is collected in a container, which can be lined with lead stirred with a hot solution of ferric sulfate, the latter being about 2 percent free sulfuric acid and 4 percent May contain ferric sulfate.
Die Anwesenheit von etwas Kupfersulfat, Ferrosulfat, arseniger Säure und Antimonverbindungen in der Lösung ist gewöhnlich festzustellen, aber diese Stoffe nehmen keinen tätigen Anteil an der Umsetzung des Schlammes.The presence of some copper sulfate, ferrous sulfate, arsenic acid and antimony compounds is usually found in the solution, but these substances do not take an active part in the conversion of the Mud.
Es wird dafür Sorge getragen, daß genug Ferrisulfat gegenwärtig ist, um nachstehende Umsetzungen zu ermöglichen. Ein Überschuß ist von Vorteil:Care is taken to ensure that enough ferric sulfate is present to prevent the following Enable implementations. An excess is beneficial:

Pb + Fe2(SOJ3 = PbSO1 + 2 FeSO, 2 As+ 3 H2O + 3 Fe2(SOJ3 - As2O3 + 6FeSO, + 3 H2SO, 2 Sb + 3 H2O + 3 Fe2(SOJ, = Sb2O3 + 6 Fe SO, + 3H2SO, 2 Bi + 3 H2 O + 3 Fe2 (SOJ3 = Bi2 O3H2SO1 + 6 FeSO, + 2 H2SO, 2 Ag+Fe2(SOJz = Ag2 SO,+ 2 FeSO,. Pb + Fe 2 (SOJ 3 = PbSO 1 + 2 FeSO, 2 As + 3 H 2 O + 3 Fe 2 (SOJ 3 - As 2 O 3 + 6FeSO, + 3 H 2 SO, 2 Sb + 3 H 2 O + 3 Fe 2 (SOJ, = Sb 2 O 3 + 6 Fe SO, + 3H 2 SO, 2 Bi + 3 H 2 O + 3 Fe 2 (SOJ 3 = Bi 2 O 3 H 2 SO 1 + 6 Fe SO, + 2 H 2 SO, 2 Ag + Fe 2 (SOJz = Ag 2 SO, + 2 FeSO ,.

Nach kurzer Zeit werden Kupferplatten in die Lösung hineingehängt, um das gelöste Silber wieder auszuscheiden. Dieser Vorgang verlangt mehrere Stunden. Nach seiner Beendigung wird die Lösung abfiltriert oder nach erfolgtem Absetzen abgezogen.After a short time, copper plates are hung into the solution in order to remove the To excrete silver again. This process takes several hours. After his At the end, the solution is filtered off or drawn off after settling has taken place.
Der unlösliche Teil des Anodenschlammes wird nach erfolgtem Auswaschen des Schlammes in einen anderen Behälter gebracht, welcher auch mit Blei ausgekleidet sein kann, und hier mit einer Lösung behandelt, welche Flußsäure (HF) enthält. Diese Behandlung dient dazu, die basischen Antimonverbindungen oder Antimonoxyd zu entfernen. Sobald dieses geschehen ist, ist der SchlammAfter the sludge has been washed out, the insoluble part of the anode sludge is brought into another container, which can also be lined with lead, and is treated here with a solution which contains hydrofluoric acid (HF) . This treatment serves to remove the basic antimony compounds or antimony oxide. Once that is done, the mud is
ίο hinreichend gereinigt, um einem Schmelzoder sonstigem bekannten Verfahren unterworfen zu werden.ίο Sufficiently cleaned to be a melting or to be subjected to other known processes.
Die Durchführung des Verfahrens gestaltet sich besonders vorteilhaft, wenn die reduzierte Eisensulfatlösung elektrolytisch aufgefrischt und zur Behandlung neuer Schlammengen wieder benutzt wird.The implementation of the method is particularly advantageous when the reduced Iron sulfate solution electrolytically refreshed and used to treat new amounts of sludge is used again.
Wenn man den durch Einwirkung auf den Schlamm reduzierten Stoff auf elektrolytischem Wege wieder oxydiert, so ist man nicht auf die Anwendung einer Sulfatlösung beschränkt. If the substance reduced by the action on the sludge is applied to electrolytic Ways re-oxidized, one is not limited to the use of a sulphate solution.
Man ist bei dem Verfahren auch nicht darauf beschränkt, Flußsäure zu benutzen, um das Antimon aus dem unlöslichen Rückstand, in welchem es sich nach dem Entfernen von Kupfer usw. befindet, herauszuziehen. Andere geeignete Lösungsmittel sind Salzsäure, Crernor Tartari und Natriumsulfid.The process is not limited to using hydrofluoric acid, the antimony from the insoluble residue, in which it is after removal of copper etc. is to be pulled out. Other suitable solvents are hydrochloric acid, Crernor tartari and sodium sulfide.
Es ist auch nicht notwendig, daß das Antimon überhaupt gelöst wird, da es durch Soda bei einem Schmelzverfahren als Schlacke abgeschieden werden kann, was leichter vor sich geht, wenn das Antimon sich in oxydiertem Zustande befindet.It is also not necessary that the antimony be dissolved at all, as it is through Soda can be deposited in a smelting process as slag, which is easier before goes away when the antimony is in an oxidized state.
Es ist zwar bereits vorgeschlagen worden, Ferrisulfatlösung zur Auslaugung von Kupfer aus Erzen zu benutzen, dagegen sind Stoffe, welche metallisches Antimon enthalten, noch nicht durch Behandlung mit Lösungen oxydierender Salze aufbereitet worden. Insbesondere ist es neu, das Antimon durch Behandlung mit der oxydierenden Lösung zu oxydieren, ohne es gleichzeitig in Lösung überzuführen, während Kupfer, Arsen usw. hierbei in Lösung übergehen, so daß eine Trennung des Antimons von den in Lösung gehenden Metallen erreicht wird.It has already been proposed to use ferric sulfate solution for the leaching of copper to use from ores, on the other hand substances which contain metallic antimony are still has not been prepared by treatment with solutions of oxidizing salts. In particular it is new to oxidize the antimony by treatment with the oxidizing solution, without it at the same time in solution transfer, while copper, arsenic, etc. here go into solution, so that a Separation of the antimony from the metals going into solution is achieved.
