oder ozonisirter Luft.or ozonized air.
Um Metallsulfide in Sulfate überzuführen, hat man schon vorgeschlagen, Ozon anzuwenden, indem man einen Strom dieses Gases oder ozonisirter Luft auf in Wasser aufgeschlä'mmte, zerkleinerte Erze oder dergl. einwirken läfst.In order to convert metal sulfides into sulfates, it has already been proposed to use ozone, by slurring a stream of this gas or ozonized air into water, allows crushed ores or the like to act.
Dieses Verfahren besitzt jedoch nach Angabe der Erfinder den Uebelstand, dafs es schwer und langsam von Statten geht und z. B. bei Verarbeitung von Kupfersulfür (Cu2 S) nicht alles Kupfer in Kupfersulfat übergeführt werden kann.According to the inventors, however, this process has the disadvantage that it is difficult and slow to carry out and B. when processing copper sulphate (Cu 2 S) not all copper can be converted into copper sulphate.
Gemäfs vorliegender Erfindung soll dieser Uebelstand vermieden werden, wenn man angesäuertes Wasser oder eine inerte Flüssigkeit zur Anwendung bringt, die Ozon zu lösen im Stande ist. Hierdurch geht die Reduction genügend rasch und vollständig von Statten, besonders wenn man die das zu behandelnde zerkleinerte Erz enthaltende Flüssigkeit in beständigen Umlauf versetzt, so dafs die Berührung zwischen den festen schwebenden Theilchen und der ozonisirten Flüssigkeit möglichst innig ist.According to the present invention, this inconvenience is to be avoided if acidified Using water or an inert liquid capable of dissolving ozone. The reduction is sufficient here quickly and completely, especially if the liquid containing the crushed ore to be treated is kept constant Circulation offset, so that the contact between the solid suspended particles and is as intimate as possible to the ozonized liquid.
Zur Ausführung des Verfahrens eignet sich eine beliebige Säure, im besonderen schweflige Säure, Schwefel-, Salz-, Salpetersäure u. s. w., oder ein solcher Stoff, welcher fähig ist, das Bad anzusäuern oder ihm durch Zersetzung die Menge der erforderlichen Säure zuzuführen.Any acid, especially sulphurous, is suitable for carrying out the process Acid, sulfuric, hydrochloric, nitric acid, etc., or such a substance which is capable of that To acidify the bath or to add the required amount of acid by decomposition.
Auch kann man jede andere Flüssigkeit anwenden, welche im Stande ist, das Ozon zu lösen und so seine Wirkung auf die in Behandlung befindliche Masse zu erleichtern. Von diesen Lösungsmitteln des Ozons sei im besonderen Terpentinöl erwähnt.You can also use any other liquid that is able to control the ozone dissolve and thus facilitate its effect on the mass being treated. from These solvents of the ozone should be mentioned in particular turpentine oil.
Behandelt man in der Weise einfache oder ^usammengesetzte zerkleinerte Schwefelerze des Bleies, Zinkes, Zinns und Antimons, so erleichtert die angewendete Säure nur die Reaction. If one treats simple or compound crushed sulfur ores in the same way Lead, zinc, tin, and antimony, the acid employed only facilitates the reaction.
Dagegen tritt bei Behandlung von z. B. Kupferstein, in welchem nicht genügend Schwefel vorhanden ist, um alles Metall in Sulfat überzuführen, mit mit Schwefelsäure angesäuertem Wasser die Schwefelsäure mit in Reaction und liefert den gewünschten Zuschufs von Schwefel.In contrast, when treating z. B. Copper stone in which there is not enough sulfur is present to convert all metal to sulfate, with acidified with sulfuric acid Water reacts with the sulfuric acid and supplies the desired addition of Sulfur.
Die Temperatur, bei welcher die Reaction stattfindet, ist gemäfs der Natur der zu behandelnden Stoffe sehr verschieden. Sie mufs jedoch genügend hoch sein, damit das Ozon einwirken kann, und genügend niedrig, damit es nicht verändert wird. Die Grenzen, zwischen denen man arbeiten kann, betragen 1 5 bis 1500 C.The temperature at which the reaction takes place varies greatly according to the nature of the substances to be treated. However, it must be high enough for the ozone to take effect and low enough so that it is not changed. The limits between which one can work are 1 5 to 150 0 C.
