   In dem Stammpatont ist ein Verfahren zur Herstellung von Skandium   bezw. Skandium-   verbindungen aus Mineralien beschrieben worden, wobei das Skandium durch   Flusssäure   
 EMI1.2 
 bezw. lösliche Salze derselbe verwendet werden können. Man kann auch gegebenenfalls eine Mischung von KIeselflusssäure mit   löslichen     kieselnusssauren Salzen   benutzen. 



   Setzt man diese   Reagentien   zur neutralen oder sauren Lösung der aus dem Wolframit. dem Zinnstein oder der Zinnschlacke durch Aufschluss mit Soda erhaltenen Oxyde zu und dampft bei   mässiger   Wärme ein, so   scheiden sich   die seltenen Erden in Form   der Sitiko-   fluoride ab, und zwar völlig frei von den anderen in der Lösung befindlichen Bestandteilen.

 flüchtigt. Aus der Lösung des auf diese   Weise erhaltenen Sulfats wird das Rohskandium   in Form des   Oxalats gefällt.

 EMI1.1
 



   In the parent patron is a process for the production of scandium BEZW. Scandium compounds from minerals have been described, with the scandium being produced by hydrofluoric acid
 EMI1.2
 respectively soluble salts the same can be used. If necessary, a mixture of silicic acid with soluble silicic acid salts can also be used.



   If one puts these reagents in the neutral or acidic solution of the wolframite. If oxides obtained by digestion with soda are added to the tin stone or tin slag and if they evaporate at moderate heat, the rare earths are separated out in the form of the sitico-fluorides, completely free of the other components in the solution.
 EMI1.3
 flees. The raw candium is precipitated in the form of the oxalate from the solution of the sulfate obtained in this way.

PATENT-ANSPRUCH : Ausführungsart des Verfahrens zur Herstellung von Skandium bezw. Skandiumverbindungen aus Mineralien, welche Skandium neben grossen Überschüssen von Hei- mengungen, namentlich Eisen und Mangan, enthalten, gemäss Stammpatent Nr. 39108, da- durch gekennzeichnet, dass zur Fällung des Skandiums anstatt Fluüsaure Kieseinusssaure oder lösliche kieselflusssaure Salze verwendet werden. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Execution of the process for the production of scandium BEZW Scandium compounds from minerals which contain scandium in addition to large surpluses of heat, in particular iron and manganese, according to parent patent no. 39108, characterized in that instead of hydrofluoric acid, silicic acid or soluble silicate salts are used to precipitate the scandium. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
