Claims (1)

Patent-Anspruch:Patent claim: Ausführungsart des Verfahrens zur Trennung von Metallen, die in Alkali löslich sind, von solche Metalle enthaltenden Stoffen durch Behandeln dieser Stoffe in geschlossenen Gefäßen unter Druck mit hocherhitzten wässerigen Alkalilösungen mit oder ohne Zusatz von Oxydationsmitteln nach Patent 224283, gekennzeichnet durch seine Anwendung für Erze, die sogenannten Färberzinnoxyde, Pasten und ähnliche Stoffe, welche die alkalilöslichen Metalle in Oxyd- oder Oxydulform enthalten, und zwar in der Weise, daß der Zusatz des Oxydationsmittels beschränkt oder ganz fortgelassen wird.Method of execution of the process for the separation of metals which are soluble in alkali are, of substances containing such metals by treating these substances in closed vessels under pressure with highly heated aqueous alkali solutions with or without the addition of oxidizing agents according to patent 224283, characterized by its application for ores, the so-called Dyeing tin oxides, pastes and similar substances, which the alkali-soluble metals in Oxyd- or Oxydulform contain, in such a way that the addition of the Oxidizing agent is limited or omitted entirely.
