Description
KAISERLICHESIMPERIAL
Die Erfindung betrifft ein Verfahren zur Behandlung von Blei- und Zinkmischerzen zwecks Gewinnung des Bleies und einer reinen Zinklösung, mittels deren z. B. kristallisiertes Zinksulfat hergestellt werden, oder die zur Bereitung sogenannter Lithoponfarben Verwendung finden kann. Als Mischerze werden entweder oxydische Erze oder Schwefelerze oder beide zusammen verwendet.The invention relates to a method for treating mixed lead and zinc for the purpose of obtaining the lead and a pure zinc solution, by means of which z. B. crystallized Zinc sulphate can be produced, or for the preparation of so-called Lithopon colors use Can be found. Mixed ores are either oxidic ores or sulfur ores both used together.
ίο Das Verfahren wird wie folgt ausgeführt:ίο The procedure is carried out as follows:
Die Blei- und Zinkmischerze werden, ohneThe lead and zinc mixers are made without
daß man sie einer vorhergehenden Röstung unterwirft, gemahlen und mit verdünnter Schwefelsäure auf kaltem Wege behandelt.that they are subjected to a previous roasting, ground and diluted with Sulfuric acid treated in a cold way.
Die Menge der benötigten Schwefelsäure wird ■ vorher durch Analyse festgestellt, damit ein geringer Überschuß an Säure vorhanden bleibt. Während der Einwirkung der Säure werden die Erze umgerührt. Nachdem sich die Lösung durch Absetzen geklärt hat, gießt man die die Zinklösung enthaltende Flüssigkeit ab, bringt den mit Blei stark angereicherten Rückstand in die Filterpresse und wäscht ihn aus. Die hierbei enthaltenen Waschwässer dienen für die Verdünnung der für die nächste Operation nötigen Schwefelsäure.The amount of sulfuric acid required is ■ determined beforehand by analysis, so that a a small excess of acid remains. Be during the action of the acid stirred the ores. After the solution has cleared by settling, it is poured removes the liquid containing the zinc solution, brings the residue, which is heavily enriched with lead, into the filter press and washes it out. The washing water contained here is used to dilute the for the next operation necessary sulfuric acid.
Der klaren, die Zinklösung enthaltenden Flüssigkeit wird hierauf fein gepulverte Blende, vorzugsweise Cadmiumblende, zugesetzt, wodurch das Cadmium sowie noch in der Lösung enthaltene Spuren von Blei ausgefällt werden. Nachdem man das Ganze einige Stunden der Ruhe überlassen hat, filtriert man ab und. sammelt den an Cadmium reichen Niederschlag, welcher z. B. zur Herstellung sögenannter Cadmiumfarben Verwendung finden kann. Durch das klare Filtrat leitet man einen Preßluftstrom, um den Schwefel auszufällen und die noch in Lösung befindlichen Eisensalze zu peroxydieren. Während des Durchleitens des Luftstromes wird eine kleine Menge fein gepulverten gerösteten Galmeis zugesetzt, der das Ausfällen der Eisensalze bewirkt. Darauf wird die Lösung filtriert und das Filtrat mit Schwefelbarium behandelt, welches eine Mischung von Schwefelzink und Bariumsulfit, das sogenannte Lithopon, ausfällt. The clear liquid containing the zinc solution is then finely powdered preferably cadmium blende, added, making the cadmium as well as still in the solution contained traces of lead are precipitated. After doing the whole thing for a few hours Has left to rest, you filter off and. collects the precipitation rich in cadmium, which z. B. for the production of so-called cadmium colors are used can. A stream of compressed air is passed through the clear filtrate to precipitate the sulfur and to peroxidize the iron salts still in solution. During the Passing through the air stream, a small amount of finely powdered roasted calme ice is added, which causes the iron salts to precipitate. The solution is then filtered and the filtrate is treated with sulphurous barium, which is a mixture of zinc sulphide and Barium sulfite, the so-called lithopone, precipitates.
Die Wirkung der Preßluft kann durch Zusatz einer geringen Menge doppelchromsauren Kalis unterstützt werden.The effect of the compressed air can be double chromic acid by adding a small amount Kalis are supported.
Einige der das Verfahren bildenden Operationen sind an und für sich bereits vorgeschlagen worden. So ist bereits angegeben · worden, Erze mit verdünnter Schwefelsäure zu behandeln; doch werden die Erze vorher geröstet und mit metallischem Zink versetzt. Bei der Erfindung dagegen werden die Erze weder geröstet noch wird ihnen Zink zugesetzt.Some of the operations that make up the procedure have already been proposed in and of themselves been. It has already been stated that ores should be treated with dilute sulfuric acid; yet the ores are made beforehand roasted and mixed with metallic zinc. In the invention, however, the ores neither roasted nor zinc added to them.
Auch die Behandlung eisenhaltiger. Zinklösung mit Preßluft ist bereits beschrieben, aber nicht in dem Zusammenhange der Operationen der vorliegenden Erfindung.Also treating ferrous. Zinc solution with compressed air has already been described, but not in the context of the operations of the present invention.
Dem Erfinder ist es darauf angekommen, natürlich vorkommende und billig zu beschaffende Mittel zur Ausführung seines Verfahrens zu verwenden. Dadurch wird dieses selbst außerordentlich einfach und billig in derIt is important to the inventor that they are naturally occurring and cheaply procured To use funds to carry out his procedure. This becomes this extraordinarily simple and cheap in itself
Durchführung und ist infolgedessen allen anderen Verfahren überlegen.Implementation and is therefore superior to all other methods.
Die Erfindung beruht in der. Vereinigung der in den nachfolgenden Patent-Ansprüchen dargelegten einzelnen Operationen.The invention resides in. Association of the following patent claims outlined individual operations.
