Description

.Verfahren zur Trennung des Eisens von anderen metallen in saurer Lösung. Versuche haben ergeben, daß Eisen durch-Nitrition in Lösungen, die HI-Ionen in geringer Konzentration enthalten, passiv wird. Diese Eigenschaft wird benutzt, um die Metalle, die unter diesen Bedingungen löslich sind, von Eisen zu trennen..Process for separating iron from other metals in acidic Solution. Experiments have shown that iron is nitrated in solutions containing HI ions contained in low concentration, becomes passive. This property is used to separate the metals that are soluble in these conditions from iron.

Im Patent 56713 wird das Entzinnen von Weißblechabfällen durch Erhitzen derselben mit geschmolzenem Kali- oder Natronsalpeter beschrieben. Das Nitrat geht dabei in Nitrit über. Die Anwendung dieses Schmelzverfahrens ist auf die Entzinnung des Eisens beschränkt. Es läßt sich nicht ohne weiteres auf Plattierungsmetalle, z. B. Kupfer oder Nickel, anwenden.In the 56713 patent, tinplate scrap is detinning by heating it the same described with molten potash or sodium nitrate. The nitrate goes at the same time in nitrite. The application of this fusion process is to detinning limited by iron. It cannot easily be applied to plating metals, z. B. copper or nickel, use.

Demgegenüber ist das neue Verfahren anwendbar auf alle Metalle, die sich in salpetriger Säure lösen. Es wird z. B. in der Weise ausgeführt, daß man die zu scheidenden Metalle unter Erwärmen mit einer Lösung behandelt, die Nitrition im - Überschuß und Essigsäure enthält.In contrast, the new process is applicable to all metals that dissolve in nitrous acid. It is z. B. carried out in such a way that one the metals to be separated are treated by heating with a solution, the nitrite ion in excess and contains acetic acid.
