  Verfahren zur Abscheidung und Trennung des Thoriums von anderen seltenen Erden. 



   Die Erfindung betrifft ein Verfahren zur Abscheidung und Trennung des Thoriums von anderen seltenen Erden und ist einerseits basiert auf die Resultate der Untersuchungen 
 EMI1.1 
 



   Nach dem den Gegenstand der Erfindung bildenden Verfahren wird demgemäss zur Abscheidung und Trennung des Thoriums von den anderen seltenen Erden, z. B. bei der Verarbeitung von Monazitsand, so vorgegangen, dass saure Lösungen der   seltenen   Erden hergestellt werden, die dann mit   Unterpbosphors & are   oder ihren leicht löslichen Salzen, z. B. unterpbosphorsaurem Natrium. behandelt werden. Dabei   fällt   das Thorium in sehr

 unterphosphorsaure Thorium wird dann nach bekannten Methoden weiter bearbeitet
Der Vorteil, der durch das Verfahren erzielt wird, besteht darin, dass die Trennung des Thoriums von den anderen seltenen Erden und der z. B. im Monazitsaed vorhaudenen

  Process for the separation and separation of thorium from other rare earths.



   The invention relates to a method for separating and separating thorium from other rare earths and is based on the one hand on the results of the investigations
 EMI1.1
 



   According to the method forming the subject of the invention is accordingly used for the separation and separation of thorium from the other rare earths such. B. in the processing of monazite sand, the procedure is that acidic solutions of the rare earths are produced, which are then treated with hypophosphorus or their easily soluble salts, e.g. B. sodium hypophosphate. be treated. The thorium falls in very much
 EMI1.2
 Hypophosphorous acid thorium is then processed further using known methods
The advantage achieved by the method is that the separation of the thorium from the other rare earths and the z. B. vorhaudenen in Monazitsaed
