 Beispiel : 
100 Teile   Leueit werden   mit 50 Teilen Calciumcarbonat innig gemischt und bei Rotglut geglüht. 



   Das erhaltene Produkt wird mit 56 Teilen Phosphat (enthaltend etwa 40% Ca2   (PO") 2)   und 60% Ca COg gemischt und sodann bis zur   Sinterung   oder bis zum Schmelzen erhitzt. Ein

 Leucit. also die Hälfte. 



     Selbstverständlich kann   man durch das eben beschriebene, in zwei Arbeitsgängen verlaufende Verfahren unter Zusatz geringer Alkalimengen ausführen. 



   Die nach vorliegendem Verfahren hergestellten Düngemittel enthalten die   Nährstoffe   mit   Rücksicht   auf den geringeren Kalkgehalt derselben in besonders konzentrierter Foim. Ein

 seits die Verluste an flüchtigem Kali vermindert werden können. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Kali und Phosphorsäure in   aufgeschlossener Form   enthaltenden Düngemitteln nach Patent Nr. 71752, dadurch gekennzeichnet, dass die zur Aufschliessung dienenden   Kalkmengen   zum Teil durch Alkali, vorzugsweise durch Soda, ersetzt werden.

 Example:
100 parts of Leueit are intimately mixed with 50 parts of calcium carbonate and ignited over red heat.



   The product obtained is mixed with 56 parts of phosphate (containing about 40% Ca2 (PO ") 2) and 60% Ca2COg and then heated until sintering or until it melts
 EMI2.1
 Leucite. so half.



     Of course, the process just described can be carried out in two steps with the addition of small amounts of alkali.



   The fertilizers produced according to the present process contain the nutrients in a particularly concentrated form, taking into account the lower lime content of the same. One

 on the other hand, the losses of volatile potash can be reduced.



   PATENT CLAIMS:
1. Process for the production of fertilizers containing potash and phosphoric acid in digested form according to patent no. 71752, characterized in that the amounts of lime used for digestion are partially replaced by alkali, preferably by soda.

Claims (1)

2. Verfahren zur Herstellung von Düngemitteln nach dem Stammpatente und nach Patentanspruch 1, dadurch gekennzeichnet, dass das alkalihaltige Gestein in Mischung mit Kalk mit oder ohne Alkalizusatz für sich geglüht wird, worauf das so erhaltene Produkt mit phosphorsäurehaltigen Mineralien gegebenenfalls unter Zusatz von weiterem Kalk oder Alkali oder beidEr auf Sinter-oder Schmelztemperatur erhitzt wird. 2. Process for the production of fertilizers according to the parent patent and according to claim 1, characterized in that the alkaline rock in a mixture with lime with or without the addition of alkali is annealed for itself, whereupon the product obtained with phosphoric acid-containing minerals, optionally with the addition of further lime or Alkali or both is heated to sintering or melting temperature.
