Description
Verarbeitung von vanadinhaltigen Erzen. Es ist bereits bekannt, Oxydationen mittels Salpetersäure so auszuführen, daß die während der Oxydation reduzierte Salpetersäure mittels Sauerstoffs unter Druck im Verlaufe des Oxydationsprozesses selbst regeneriert wird.Processing of ores containing vanadium. It is already known to oxidations by means of nitric acid in such a way that the nitric acid reduced during the oxidation self-regenerates by means of oxygen under pressure in the course of the oxidation process will.
Es hat sich nun ergeben, daß diese Arbeitsweise zum Aufschluß und zur Verarbeitung @-on vanadiumhaltigen Erzen benutzt werden kann, wobei es dahingestellt sein soll, ob es sich im einzelnen stets um einen reinen Oxydationsvorgang der im vanadiumhaltigen Material enthaltenen Körper handelt.It has now been found that this method of working for digestion and can be used for processing @ -on vanadium-containing ores, although it is an open question should be whether it is always a pure oxidation process of the im vanadium-containing material is the body.
Beispiel. Fein gepulvertes Vanadinerz nicht sulfidischen Charakters, das neben V vor allem Blei und Zink enthält, wurde mit einer relativ kleinen Menge Salpetersäure, dagegen so viel Schwefelsäure, daß sie mehr als hinreicht, um alle gegenwärtigen Metalle in Sulfate zu verwandeln, unter starkem Rühren in einem Autoklaven aus V= A-Metall und unter Sauerstoffdruck von 3o Atm. bei r2o° C einige Stunden erhitzt. Hiernach war alles, mit Ausnahme von dem als Sulfat vorhandenen Pb, in Lösung gegangen, und zwar auch das -V restlos. Dieses katalysiert dabei den Vorgang der Regenerierung der Salpetersäure aus den gebildeten niederen Oxyden des Stickstoffes, Sauerstoff und Wasser. Aus dem Reaktionsprodukt wurde nach dem Abfiltrieren vom Bleisulfat die Salpetersäure im Vakuum abgetrieben und verlustlos wiedergewonnen. Der Rückstand läßt sich nach bekannten Methoden einerseits auf Oxyde des Vanadiums, andererseits auf Zink verarbeiten.Example. Finely powdered vanadium ore of non-sulphide character, which contains lead and zinc in addition to V, was used in a relatively small amount Nitric acid, on the other hand, so much sulfuric acid that it is more than sufficient for all Convert current metals into sulfates, with vigorous stirring in an autoclave made of V = A-metal and under an oxygen pressure of 30 atm. at r2o ° C for a few hours heated. According to this, everything, with the exception of the Pb present as sulfate, was in Solution gone, including the -V completely. This catalyzes the process the regeneration of nitric acid from the formed lower oxides of nitrogen, Oxygen and water. From the reaction product was filtered off from Lead sulphate removes the nitric acid in a vacuum and recovered it without loss. The residue can be based on the one hand on oxides of vanadium, on the other hand, process on zinc.
Das beschriebene neue Verfahren ermöglicht bequemer, billiger und rascher als irgendeines der bekannten und, was bei dem wertvollen Material besonders wichtig, völlig verlustlos Vanadium aus irgendwelchen vanadiumhaltigen Erzen oder solches enthaltendem anderen Material in Lösung und damit in eine von den Begleitern leicht trennbare Form zu bringen.The new method described allows more convenient, cheaper and faster than any of the known and what is particularly important with the valuable material important, completely lossless vanadium from any vanadium-containing ores or such containing other material in solution and thus in one of the companions to bring easily separable form.
Ebenso kann man sulfidische V-haltige Erze verarbeiten, wobei gegebenenfalls der Zusatz von Schwefelsäure entbehrt werden kann.Likewise, one can process sulfidic V-containing ores, where appropriate the addition of sulfuric acid can be dispensed with.
