Description
Gewinnung von Vanadin aus dieses enthaltenden Schlacken und Hochofengichtstaub Um - das Vanadin aus Frischschlacke zu gewinnen, wird das Schlackenmehl nacheinzrn bekannten Verfahren mit Kochsalz geröstet und das Produkt mit Wasser ausgezogen. Der Rückstand wird-tvieder verhüttet, die Lösung auf Vanadin verarbeitet.Extraction of vanadium from slag and blast furnace top dust containing it In order to - win the vanadium from fresh slag, the slag meal is refined known method roasted with table salt and extracted the product with water. The residue is smelted again, the solution processed for vanadium.
Der in großen :Mengen bei der Trockenreinigung der Hochofengichtgas.e anfallend: Flugstaub wird meistens nicht verwertet, ob- gleich er neben etwa 2o0o Schw-erme.tallen beträchtliche Mengen Kalisalze und Jod enthält. Einer lohnenden Verwertung steht das niedrige Schüttgewicht (r 1 wiegt 2rog), das den Transport verteuert, entgegen. Weite_-liin stören gewisse organische Verbindungen die Weiterverarbeitung des mit Wasser gewonne-' rnen Extraktes, der die Kalisalze und die Jodsalze enthält. Ein Abrösten der organischen Verbindungen wäre bereits unwirtschaftlich. Das Brikettieren oder Agglomerieren des für die Verhüttung minderwertigen Filterst iubes lohnst sich ebenfalls nicht.- Aus diesen Griinden wird der Flugstaub meistens auf die Halde gegeben..In large: accruing amounts in dry cleaning of Hochofengichtgas.e: fly ash is usually not utilized, incumbent equal it contains about 2o0o Sw-erme.tallen considerable amounts of potassium salts and iodine. The low bulk weight (r 1 weighs 2 troughs), which makes transport more expensive, stands in the way of profitable utilization. In addition, certain organic compounds interfere with the further processing of the extract obtained with water, which contains the potassium and iodine salts. Roasting the organic compounds would already be uneconomical. Briquetting or agglomeration of the filter dust, which is inferior for smelting, is also not worthwhile.
Erfindungsgemäß gelingt eine -wirtschaftliche Verwertung des Flugstaubes. Sie beruht darauf, daß die im Hochofengichtstaub enthaltenen Alkalien, bevor sie extrahiert werden, zum aufsch,luß von Vanadinschlacke benutzt werden. Zwecks Durchführung des Verfahrens mischt man die gemahlene Vanadins.chlacke mit so viel Flugstaub, daß das belLa.nmte Verhältnis zwischen V_0; und Alkali erreicht wird, und@röstet an der Luft wie bisher bei 8oo bis goo-. Das Röstgut -wird extrahiert und die wäßrige Lösung in bekannter Weise auf Vanadin verarbeitet. Die Restlösung enthält die wertvollen Kalisalze und das Jod. Der wirtschaftliche Fortschritt gegenüber dem normalen Aufschlußverfahren mit Kochsalz geht aus folgenden Gesichts=;'. punkten hervor t. Verwertung der Kalisalze und des %'J4)'4 des Flugstaubes.According to the invention, the fly ash can be used economically. It is based on the fact that the alkalis contained in the blast furnace dust before they can be extracted, to be used to dissolve vanadium slag. For the purpose of implementation of the process, you mix the ground Vanadins.chlacke with so much fly ash, that the significant relationship between V_0; and alkali is reached, and @ roasts in the air as before at 8oo to goo-. The roast is extracted and the water Solution processed in a known manner on vanadium. The remaining solution contains the valuable ones Potash salts and the iodine. The economic progress compared to the normal digestion process with table salt results from the following face =; '. score emerge t. Utilization of the potassium salts and the% 'J4)' 4 of the fly ash.
z. Zerstörung der organischen VerbinIdungen; die die Verarbeitung des Flugstaubextraktes auf Jod stören und :die Kalisalze verunreinigen, 3. Einsparen des Kochsalzes, q.. Verwertung der Schwermetalle des Flugstaubes. Durch den- Laugungsprozeß werden die Schwermetalle des Flugstaubes angereichert und-beim Verhütten der extrahierten Röstmischung wiedergewonnen.z. Destruction of organic compounds; which the processing of the fly dust extract interfere with iodine and: contaminate the potassium salts, 3. save of table salt, q .. utilization of the heavy metals of the fly ash. Through the leaching process The heavy metals of the fly ash are enriched and - when smelting the extracted Roast mixture recovered.
Es ist bereits bekannt, bei der oxydierenden Rösturig voll Vanadinerzen einen Teil des dabei verwendeten Kochsalzes durch Salpeter oder Alkalicarbonat oder Alkalihydroxyd zu ersetzen. Die vorliegende Erfindung betrifft aber nicht .den ganzen oder teilweisen Ersatz des Kochsalzes beim Rösten von Vanadinerzen durch andere geeignete Verbindungen, sondern die Verwendung von Gichtstaub zum Aufschluß von Vanadinschlacke, wodurch dieser einer vorteilhaften Nutzbarmachung zugeführt wird, die aus den oben angegebenen Gründen bis jetzt nicht möglich war.It is already known that the oxidizing roasting is full of vanadium ores part of the table salt used by saltpeter or alkali carbonate or To replace alkali hydroxide. However, the present invention does not relate to the whole or partial replacement of table salt when roasting vanadium ores with others suitable compounds, but the use of gout dust for the digestion of Vanadium slag, whereby it is fed to an advantageous utilization, which was not possible until now for the reasons given above.
