PATENT-ANSPRUCHE : 1. Verfahren zur Behandlung von Materialien, welche Metalle enthalten, die mehrere Oxydationsstufen besitzen und deren höchste Oxydationsstufe in Alkali oder in Alkalikarbonaten in schmelzflüssigem Zustande oder in wässcriger Lösung löslich sind, insbesondere von vanadinhaltigem Material durch Schmelzen des Ausgangsproduktes mit Alkalikarbonaten unter Anwendung eines Oxydationsmittels, dadurch gekennzeichnet, dass das zu verarbeitende Material zunächst nur mit Alkalikarbonaten vermischt und geschmolzen wird und das Oxydationsmittel EMI5.1 genommen hat, eingebracht wird, indem man z. B. Natriumnitrat auf das entstandene Bad wirft. PATENT CLAIMS: 1. Process for the treatment of materials which contain metals which have several oxidation levels and whose highest oxidation level is soluble in alkali or in alkali carbonates in a molten state or in aqueous solution, in particular of vanadium-containing material by melting the starting product with alkali carbonates using an oxidizing agent, characterized in that the material to be processed is initially only mixed with alkali carbonates and melted, and the oxidizing agent EMI5.1 has taken, is introduced by z. B. Sodium nitrate throws on the resulting bath. 2. Ausführuugsform des Verfahrens nach Anspruch l zur Verarbeitung vanadinreicher und siliziumarmer Materialien, dadurch gekennzeichnet, dass man nach Beendigung des Oxydationsvorganges die flüssige Masse in Wasser oder schwacher Lauge. die von der früheren Behandlung erschöpfter Schlacken herrührt, einfliessen lässt, um sie vor dem Auslaugen abzuschrecken. 2. Embodiment of the method according to claim l for processing vanadium-rich and low-silicon materials, characterized in that the liquid mass in water or weak alkali after completion of the oxidation process. which stems from the previous treatment of exhausted slags, flows in to deter them from leaching. 3. Ausführungsform des Verfahrens nach Anspruch l zur Verarbeitung vanadinarmer und siliziumreicher Materialien, dadurch gekennzeichnet, dass man die geschmolzene Masse ohne EMI5.2 auslaugt. 3. Embodiment of the method according to claim l for processing low-vanadium and silicon-rich materials, characterized in that the molten mass without EMI5.2 leaches. 4. Verfahren zur Gewinnung von Metallen, die mehrere Oxydationsstufen besitzen, wie z. B. des Vanadins aus Alkalilösungen, die das Meta !) in Form eines Aikalisalze.-fithalter', dadurch EMI5.3 zureichenden enge Schwefelsäure versetzt wird, wobei ein Teil der Kieselsäure ausfällt, worauf der Rest der Kieselsäure in an sich bekannter Weise durch Zusatz eines höheren Oxyden des zu gewinnenden Metalles ausgeschieden wird. EMI5.4 4. Process for the extraction of metals that have several stages of oxidation, such as. B. vanadium from alkali solutions, which the meta!) In the form of an Aikalisalze.-fithalter ', thereby EMI5.3 Sufficient close sulfuric acid is added, with part of the silica precipitating, whereupon the remainder of the silica is precipitated in a manner known per se by adding a higher oxide of the metal to be recovered.
