Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr.     120815.       Verfahren zur Herstellung eines Düngemittels.    In dem Hauptpatent ist ein Verfahren be  schrieben, mit dessen Hilfe es möglich ist,  unter Verwendung von     Phosphoriten    und Al  ka.lisalzen einen     Phosphorsäure-Dünger    zu  gewinnen, und zwar findet der Aufschluss bei       Gegenwart    von Kieselsäure statt. Die Er  findung bezieht. sich nun auf     eine    besondere  Ausgestaltung     dieses    Verfahrens, bei welcher  stark kieselhaltige     Phosphorite    zur Anwen  dung gelangen.

   Hierdurch wird für diese  minderwertigen     Phosphorite,    die zum Bei  spiel für die     Superphosphatfabrikation    nicht  brauchbar sind. ein     gewinnbringendes    An  wendungsgebiet geschaffen.    Der Aufschluss     kann    in analoger Weise  wie im Hauptpatent beschrieben ausgeführt  werden.



  <B> Additional patent </B> to main patent no. 120815. Process for the production of a fertilizer. The main patent describes a process with the help of which it is possible to obtain a phosphoric acid fertilizer using phosphorites and alkali salts, and the digestion takes place in the presence of silica. The invention relates. now focus on a special embodiment of this process, in which highly siliceous phosphorites are used.

   This is for these inferior phosphorites, which are not usable for example in superphosphate production. a profitable area of application created. The digestion can be carried out in a manner analogous to that described in the main patent.
