Es ist bekannt, aus vanadinhaltigen Erzen das Vanadin in der Weise zu gewinnen, daß das zerkleinerte Erz durch Kochen in einer Säure, zweckmäßig Schwefelsäure, zu einem dünnen Brei umgewandelt wird, in dem die Vanadinsäure gelöst ist. Bei sandsteinartigen Erzen wird der Lösung als oxydierendes Mittel Natriumnitrat hinzugefügt, um das im Erz enthaltene Vanadinoxyd leichter löslichIt is known that vanadium can be obtained from ores containing vanadium in such a way that the crushed ore by boiling in an acid, expediently sulfuric acid, to one into a thin paste in which the vanadic acid is dissolved. With sandstone-like Ores, sodium nitrate is added to the solution as an oxidizing agent to reduce the im Vanadium oxide containing ore is more easily soluble
ίο zu machen. Es entsteht dann eine schwerflüssige Masse, die schwefelsaures Vanadin und alle anderen im Erz vorhandenen Metalle in entsprechenden Verbindungen enthält. Aus dieser Masse wird endlich durch weitere chemische oder elektrolytische Behandlung das Vanadinpentoxyd (V2 OJ gewonnen und auf Vanadin weiter verarbeitet.ίο to make. A heavy-bodied mass then arises, which contains sulfuric acid vanadium and all other metals present in the ore in appropriate compounds. From this mass the vanadium pentoxide (V 2 OJ is finally obtained by further chemical or electrolytic treatment and further processed on vanadium.
Die Erfindung bezieht sich auf ein Verfahren, das durch einfache Behandlung derThe invention relates to a method that by simply handling the
Erze unmittelbar reines Vanadinpentoxyd^ OJ, also frei von allen anderen Metallen, ergibt. Zu diesem Zweck wird nach der Behandlung des zerkleinerten Erzes in einer heißen Säurelösung aus den dadurch gelösten Bestandteilen das Vanadin durch ein Chlorat, wie Natriumoder Kaliumchlorat, als Vanadinhydrat ausgeschieden, das nach Entfernen des Hydratwassers durch Trocknen reines Vanadinpentoxyd (V2 O6) ergibt. Dadurch wird gegenüber den bekannten Verfahren die Gewinnung des Vanadins wesentlich vereinfacht und zugleich ein von allen anderen Metallen freies Vanadin unmittelbar erhalten.Ores immediately give pure vanadium pentoxide ^ OJ, that is, free from all other metals. For this purpose, after treating the crushed ore in a hot acid solution, the vanadium is excreted from the dissolved constituents by a chlorate, such as sodium or potassium chlorate, as vanadium hydrate, which after removal of the water of hydration by drying gives pure vanadium pentoxide (V 2 O 6 ) . As a result, the extraction of the vanadium is considerably simplified compared to the known processes and at the same time a vanadium free of all other metals is obtained directly.
Nach dem neuen Verfahren wird das Erz bis etwa zur Korngröße von etwa 1 bis 2 mm gemahlen und dann mit einer Säure, vorzugsweise mit verdünnter Schwefelsäure, die zur Lösung dienen soll, in einem Gefäß mit Dampf gekocht. Die erhaltene Lösung enthält alles Vanadin und andere lösliche Metalle, die von Anfang an im Erz vorhanden waren; die Lösung wird dann in einen Setzbehälter dekantiert und so von den nicht gelösten Bestandteilen getrennt. Hierauf pumpt man die Lösung nach dem Abklären in ein Ausfällgefäß, in dem sie mit Dampf gekocht wird und mit einer gewissen Menge eines als -starkes Oxydationsmittel wirkenden Chlorates, wie Natrium- oder Kaliumchlorat, vermengt wird, das das ganze Vanadin in Form eines roten Hydroxyds zur Ausfällung bringt. Das Ausfällen in der Lösung kann bei großem Säureüberschuß oder auch nach Neutralisierung mit einem Alkali vorgenommen werden. Die ausgefällte Masse besteht aus praktisch vollkommen reinem Vanadinhydrat und wird von der darüberstehenden Lösung durch Filtrieren oder Dekantieren getrennt und von den Rückständen durch Auswaschen befreit. Das gereinigte Vanadinhydroxyd wird bei entsprechend hoher Temperatur zum Trocknen gebracht, wodurch unter Entfernung allen Hy-According to the new process, the ore is made up to a grain size of about 1 to 2 mm ground and then with an acid, preferably with dilute sulfuric acid, which for Solution intended to serve, cooked in a vessel with steam. The solution obtained contains everything Vanadium and other soluble metals that were present in the ore from the start; the solution is then decanted into a settling container and so from the undissolved constituents separated. After clarification, the solution is then pumped into a precipitation vessel in which it is boiled with steam and with it a certain amount of a chlorate that acts as a strong oxidizing agent, such as sodium or potassium chlorate, which causes all of the vanadium to precipitate in the form of a red hydroxide. The failure in the solution can be carried out with a large excess of acid or after neutralization with an alkali. The precipitated one The mass consists of practically completely pure vanadium hydrate and is filtered from the overlying solution or decanting separately and freed from the residues by washing. The cleaned Vanadium hydroxide is dried at a correspondingly high temperature, which removes all hy-
