Description

Vorbereitung von Erzen und Hüttenprodukten für die 1Vletallgewinnung. Gemäß Hauptpatent werden die Erze zur Umwandlung in leichtlösliche Stoffe mit Salpeterlösung im Bade behandelt. Nach der Behandlung werden die vorbereiteten Erze in ein Lösungsmittel gebracht, so daß die vorbehandelten Erze in Lösung gehen, aus welcher sie wieder abgeschieden werden.Preparation of ores and metallurgical products for 1metal extraction. According to the main patent, the ores are converted into easily soluble substances with nitric solution treated in the bath. After treatment, the prepared ores are placed in a solvent brought so that the pretreated ores go into solution, from which they again to be deposited.

Vorliegende Erfindung betrifft nun eine wesentliche Vereinfachung und Verbesserung des im Hauptpatent angegebenen Verfahrens. Das neue Verfahren beruht auf der Erkenntnis, daß das Mittel für die Umwandlung der Erze in löslichen Zustand mit dem Lösungsmittel selbst vereint werden kann, so daß in einem Bade die Umwandlung und Lösung der Erze stattfinden kann. Damit ist für die Praxis ein großer Vorteil durch Vereinfachung der Arbeit durch Beschleunigung derselben usw. herbeigeführt. Die praktische Durchführung-gestaltet sich sehr einfach und läßt sich für verschiedene Lösungsmittel je nach der Art der zu behandelnden Erze anwenden.The present invention now relates to a substantial simplification and improvement of the process specified in the main patent. The new procedure is based on the knowledge that the means for transforming the ore into soluble state can be combined with the solvent itself, so that the conversion takes place in one bath and dissolution of the ores can take place. This is a great advantage in practice brought about by simplifying the work by speeding it up, etc. The practical implementation is very simple and can be used for different purposes Use solvents depending on the type of ore to be treated.

Das Bad, in welchem die Erze behandelt werden, wird aus der Lösung von Salpeter oder anderen Nitraten und aus dem Lösungs-Rnittel selbst gebildet; beispielsweise kommt als Lösungsmittel Kochsalz oder Kalziumchlorid in Frage, auch Säuren kommen als Lösungsmittel in Frage. Die Menge, in welcher das Lösungsmittel dem Oxydationsmittel zugeführt wird, hängt von den vorlieo-enden Verhältnissen ab und ist beliebig veränderlich.The bath, in which the ores are treated, becomes out of the solution formed from saltpetre or other nitrates and from the solvent itself; for example, table salt or calcium chloride are also suitable as solvents Acids can be used as solvents. The amount in which the solvent is added to the oxidizing agent, depends on the prevailing conditions and can be changed at will.
