Description

Verfahren zur Herstellung von Kalisalpeter aus Kalirohsalzen- nach Anspruch 1 und 3 des Patents 335819. In dem Patent 374095 ist ein Verfahren zur Herstellung von . Kalisalpeter aus Kalirohsalzen .beschrieben worden. Die Rohsalze werden dort zunächst mit kaltem Wasser oder geeigneten kalten Laugen behandelt, um den darin enthaltenen Kieserit zu isolieren. Das abgetrennte Magnesiumsulfat wird sodann in Magnesiumnitrat umgewandelt, welches in Form einer Maggnesiumnitratlauge zur Behandlung des nach der Albtrennung des Kieserits verbleibenden Salzgemisches Verwendung findet.Process for the production of potassium nitrate from crude potash salts according to claim 1 and 3 of the patent 335819. In the patent 374095 is a process for the production of. Potash nitrate from crude potash salts. Has been described. The crude salts are first treated there with cold water or suitable cold alkalis in order to isolate the kieserite contained therein. The separated magnesium sulfate is then converted into magnesium nitrate, which is used in the form of a magnesium nitrate liquor to treat the salt mixture remaining after the kieserite has been separated.

Der hauptsächlichste Nachteil dieser Arbeitsweise besteht idarin, !daß bei der Absahlämmung des Kieserits weitgehend auch andere.Salzanteile mit entfernt werden, welche entweder zu empfindlichen Betriebsverlusten Veranlassung geben oder ,doch wenigstens die Herstellung @derMagnesiumnitratlauge, welche zweckmäßig nach Patentschrift 32103o erfolgt, erschweren.The main disadvantage of this way of working is that ! that when the kieserite is blown off, other salt components are also largely removed which either give rise to sensitive operating losses or , but at least the production of the magnesium nitrate lye, which is useful after Patent 32103o takes place, complicate.

Es wurde gefunden, idaß man diese Übelstände vermeidet, wenn der Kieserit erst nach erfolgter Auslaugung der Rohsalze abgetrennt wind. Man arbeitet dann an sich in genau dersed@benWeise wie heute bei -der Fabrikation von Chlorkalium. In diesem Falle löst .man mit Mg C124haltigen Laugen, während bei der Herstellung von Kalisalpeter Magnesiumnitrat enthaltende Laugen in Anwendung kommen. In ibeiden .Fällen :ist der Kieserit, zumal bei abgekürzter Lösedauer, praktisch unlöslich.It has been found that these inconveniences are avoided if the kieserite separated only after the crude salts have been leached. Then you work on in exactly the same way as today in the manufacture of potassium chloride. In In this case one dissolves with Mg C124-containing alkalis, while in the production of Caustic solutions containing potassium nitrate magnesium nitrate are used. In both .Cases: the kieserite is practically insoluble, especially if the dissolving time is shortened.

Aus dem nach :der Löseoperation verbleibenden Rückstand, der in- der Hauptsache aus Chlornatrium besteht, wird nun ,in geeigneten Sieb- und Schlämmvorrichtungen der Kieserit abgetrennt. Das auf diese Weise gewonnene, mehr oder weniger reine Magnesiumsulfat wird am besten mit Hilfe des in Patentschrift 32103o niedergelegten »Kreislaufverfahrens« in Magnesiasalpeter umgewandelt. Man gewinnt etwa eine Magnesiumnitratlauge mit 30o g Mg (N 03)= pro Liter Lauge. Diese findet sodann nach erfolgter Zumischung vorhandener Betriebslaugen gemäß Anspruch 3 ;des Patentes 335$i9 zur Behandlung ides Rohsalzes Verwendung.From the residue remaining after: the dissolving operation, the ind Mainly consists of sodium chloride, is now, in suitable sieving and slurry devices the kieserite separated. That which is obtained in this way, more or less pure Magnesium sulfate is best prepared using the method set forth in Patent 32103o "Circulatory process" converted into magnesia nitrate. A magnesium nitrate liquor, for example, is obtained with 30o g Mg (N 03) = per liter of lye. This then takes place after the admixture has taken place existing service liquors according to claim 3; of the patent 335 $ 19 for treatment ides crude salt use.
