Description

Verfahren zur Gewinnung von Vanadin aus vanadinhaltigen Eisenerzen Es ist bereits. vorgeschlagen war-den, vanadinhaltige Eisenerze mit Soda zu rösten und dann das entstandene Alkalivanadat aus den Röstprodukten mit Wasser auszulaugen. Dabei war man. aber bestrebt, während dies Röstens ein Sintern des. Materials so weit wie möglich zu verhindern, um das gesinterte Gut vor dem Auslaugen nicht nochmals mahlen zu müssen.Process for the extraction of vanadium from iron ores containing vanadium It is already. It was suggested to roast iron ores containing vanadium with soda and then leach the resulting alkali vanadate from the roasted products with water. One was there. but endeavors to sinter the material during this roasting as much as possible to prevent the sintered material from being leached again having to grind.

Durch Untersuchungen ist vom Erfinder festgestellt, worden, daß Alkal:ivanad.'at sich aus nach bekannten Verfahren hergestellten Sinterkörpern von zur Beschickung von Hochöfen: geeigneter Stückengröße praktisch vollständig mit Wasser auslaugen läßt.The inventor has established through investigations that alkali: ivanad.'at from sintered bodies produced by known processes for charging from blast furnaces: leach out practically completely with water of suitable size leaves.

Die Erfindung beruht auf dieser Entid@ckung unch ist in: .der Hauptsache dadurch gekennzeichnet, daß das Ausgangsmaterial, in gepulverter und zweckmäßig kornzentrierter Form (z. B. als Eiisenerzschl,iech.) mit einer Alkaliverbindung, wie Soda, gemischt und danach - gegebenenfalls nach Brdkettierung - unter oxydierenden Bie-dingungen zwecks überführung dies Vanadingehaltes in wasserlösliches Vanad@at gesintert wird, worauf dias Sinberprodukt in einer zur Bieschickung von Hochöfen üblichen Stückenform mit Wasser ausgeIaugt und die Lange in, an sich bekannter Weise auf Vanadin verarbeitet wird.The invention is based on this discovery in: .the main thing characterized in that the starting material, in powdered and expedient grain-centered form (e.g. as iron ore slug, iech.) with an alkali compound, like soda, mixed and then - if necessary after Brdkettierung - under oxidizing Bending conditions for the purpose of converting this vanadium content into water-soluble Vanad @ at is sintered, whereupon the sintered product in a to be sent by Blast furnaces leached out with water in the usual piece shape and the length in a manner known per se processed on vanadium.

Wie aus vorstehendem hervorgeht, kann man also auch das gewöhnliche Sinterverfahren in Sinterpfannen anwenden und das Sintergwt in gewöhnlicher Weise nur so weit zerbrechen, daß ein für die Beschickung eines Hochofens geeignetes Produkt entsteht. Das Verfahren gemäß der Erfindüng ist also gleichsam auf die Maßnahme des Zusetizens von Al:kaliverbindung zu, dem Au,sgangsmaterial und des Auslaugens dies Endproduktes mit Wasser in dem gewöhnlichen Sinterprozeß vereinfacht. Beispiel Ein titanr und vanadinhaltiger Eisenerzschliech, enthaltend o,6°/o Vanadin, wurde mit 5 % Soda gemischt und zu Briketts .gepreßt, die bei einer Temperatur zwischen i ioo und 1300' C gesintert wurden. Diese Briketts wurden, ohne zuerst zerkleinert zu werden, mit Wasser in der Wärme ausgelaugt. Hierbei wurden in der Lösung 97 °/o des im Ausgangsmaterial als Begleitstoff enthaltenen Vanadingehaltes gewonnen.As can be seen from the above, one can also do the ordinary Use the sintering process in sintering pans and the sintering quality in the usual way only break so far that a product suitable for charging a blast furnace arises. The method according to the invention is so to speak on the measure the addition of alkali metal compound to the starting material and the leaching simplifies this end product with water in the ordinary sintering process. example A sheet of iron ore containing titanium and vanadium, containing 0.6% vanadium mixed with 5% soda and pressed into briquettes that are kept at a temperature between ioo and 1300'C were sintered. These briquettes were crushed without being first to be leached with water in the heat. In the solution, 97 per cent of the vanadium content contained in the starting material as an accompanying substance.
