Description

Verfahren zum Rösten und Laugen vanarlinhaltiger Schlacken Beim chlorierenden Rösten vanadinhaltiger Schlacken zwecks Vanadingewinnung hat sich gezeigt, daß bei der zum Rösten erforderlichen Temperatur von z. B. etwa joo° C das Röstgut vielfach zur hlumpenbildung neigt, die eine befriedigende Röstung verhindert. Die Folge der ungenügenden Röstung ist aber, daß beim Auslaugen des Röstgutes ein großer Teil des Vanadins im Röstgut unlöslich bleibt und gegebenenfalls eine zweite Röstung erfordert.Process for roasting and leaching vanarlin-containing slags Roasting vanadium-containing slag for the purpose of vanadium recovery has been shown that with the temperature required for roasting of z. B. about joo ° C the roasted food many times tends to form lumps, which prevents satisfactory roasting. The consequence of the Inadequate roasting is that a large part of the leaching of the roasted material of the vanadium remains insoluble in the roasted food and, if necessary, a second roast requires.

Die Erfindung bezweckt, die Vanadinausbeute der vanadinhaltigen Schlacken zu erhöhen. Dieser Zweck wird nach der Erfindung dadurch erreicht, daß bei der Gewinnung von Vanadin durch Rösten und Laugen von vanadinhaltigen Schlacken und anschließende Weiterverarbeitung der gewonnenen vanadinhaltigen Lösung den vanadinhaltigen Schlacken vor dem Rösten eisenoxydhaltige Stoffe, z. $. Eisenerz, zugesetzt werden.The aim of the invention is to determine the vanadium yield of the vanadium-containing slags to increase. This purpose is achieved according to the invention that in the extraction vanadium by roasting and leaching vanadium-containing slags and then Further processing of the obtained vanadium-containing solution into the vanadium-containing slags before roasting substances containing iron oxide, e.g. $. Iron ore, may be added.

Durch den Zusatz eisenoxy dhaltiger Stoffe, die den Erweichungspunkt des Röstgutes zu höheren Temperaturen verschieben, wird erreicht, daß; die hlumpenbildung beim Rösten vermieden wird und eine weitgehende Durchröstung des ganzen Röstgutes erfolgt. Auf diese Weise kann man nicht nur die Vanadinausbeute erhöhen, sondern auch ein nochmaliges Rösten vermeiden.By adding iron oxide-containing substances, which increase the softening point move the roasted food to higher temperatures, it is achieved that; the lump formation is avoided during roasting and extensive roasting of the whole roasted material he follows. In this way you can not only increase the vanadium yield, but also also avoid roasting again.

Eine weitere Verbesserung der Vanadinausbeute des Röstgutes kann man in an sich bekannter Weise erreichen, indem man das Röstgut bei der höchsten Rösttemperatur aus dem Ofen nimmt und es möglichst ohne vorherige Abkühlung ins Wasser bringt und auslaugt. Auf diese Weise kann man etwa 9-51/o des im Röstgut enthaltenen Vanadins auslaugen.A further improvement in the vanadium yield of the roasted material can be achieved can be achieved in a manner known per se by the roasted material at the highest roasting temperature takes it out of the oven and inserts it into water brings and leaches. In this way you can get about 9-51 / o of the amount contained in the roasted food Leach vanadins.
