BRUNO BERNHARDI in STASSFURT. Neuerungen in der Verarbeitung von Salzlaugen, welche Kaliumverbindungen enthalten.BRUNO BERNHARDI in STASSFURT. Innovations in the processing of brine, which contain potassium compounds.
Patentirt im Deutschen Reiche vom 18. December 1879 ab.Patented in the German Empire on December 18, 1879.
Bei den bisher befolgten Methoden der Gewinnung von Schönit, sowie von schwefelsaurem Kali aus Chlorkalium + schwefelsaurer Magnesia, oder aus Chlorkalium + Schönit resultiren Mutterlaugen , welche einen bedeutenden Gehalt an Kalisalzen haben und die seither im wesentlichen durch Verdampfung nutzbar gemacht wurden.In the previously followed methods of extracting Schönite and sulfuric acid Potash from potassium chloride + magnesia sulfuric acid, or mother liquors result from potassium chloride + schoenite which have a significant content of potash salts and which have been essentially since then have been made usable by evaporation.
Diese Behandlung verursacht nicht nur bedeutende Verluste, sondern erheischt nebenbei grofsen, Brennmaterialaufwand; auch ermöglicht dieselbe in der Hauptsache nur die Gewinnung von Chlorkalium bezw. Carnallit.This treatment not only causes significant losses, it also requires incidentally large, fuel consumption; also, in the main, it only enables extraction of potassium chloride or. Carnallite.
Ich ziehe vor, diesen Mutterlaugen schwefelsaure Magnesia in flüssiger oder fester Form, auch als Kieserit hinzuzufügen, und zwar entweder kalt oder unter Erwärmung der Laugen. Es bilden sich hierdurch Doppelsalze von schwefelsaurem Kali mit schwefelsaurer Magnesia, welche sich unter geeigneten Bedingungen ausscheiden. I prefer to use these mother liquors with magnesia sulfuric acid in liquid or solid form, can also be added as kieserite, either cold or with heating of the lye. As a result, double salts of sulphate of potash with sulphate of magnesia are formed, which are eliminated under suitable conditions.
Genügt obige Behandlung mit schwefelsaurer Magnesia nicht, um den Kaligehalt der Laugen entsprechend herabzudrücken, so kann dieselbe Behandlung ein oder mehrere male wiederholt werden.Is the above treatment with sulphate of magnesia not sufficient to reduce the potash content of the lyes to press down accordingly, the same treatment can be repeated one or more times will.
Die resultirenden Endlaugen eignen sich zur Behandlung von Kainit bezw. Carnallit in ausgezeichneter Weise, und bieten bei Benutzung der sonst bekannten Methoden zur Verarbeitung jener Salze den grofsen Vortheil, dafs der in den Endlaugen enthaltene Restantheil Kali noch nutzbar gemacht wird.The resulting final liquors are suitable for the treatment of kainite respectively. Carnallite in excellent Way, and offer when using the otherwise known methods of processing those salts have the great advantage that the residual potash contained in the final liquors is still is made usable.
Wie für die oben bezeichneten Mutterlaugen, so eignet sich dies Verfahren auch für alle Kali enthaltenden Salzlaugen.As for the mother liquors described above, this process is also suitable for all potash containing brine.
. Obgleich die von mir benutzte Reaction von Anderen bei der Darstellung von Schönit bezw. schwefelsaurem Kali für die zu diesem Zwecke besonders hergestellten ersten Salzlösungen oder Salzmischungen angewendet worden ist, so ist doch die Behandlung der hierbei resultirenden Mutterlaugen mit schwefelsaurer Magnesia unzweifelhaft neu und eigenthümlich; auch ist es charakteristisch, dafs der Kaligehalt der Mutterlaugen statt als Chlorkalium bezw. Carnallit, als schwefelsaures Salz nutzbar gemacht werden kann.. Although the reaction of others used by me in the representation of Schönit resp. sulphate of potash for the first salt solutions specially prepared for this purpose or mixtures of salts have been used, the treatment is the resultant Mother liquors with sulphate of magnesia undoubtedly new and peculiar; also it is characteristic that the potash content of the mother liquors instead of potassium chlorine or Carnallite, can be made usable as sulfuric acid salt.
Endlich ist es von Werth und auch neu, dafs der in den Endlaugen verbleibende Kalirest, sowie die schwefelsaure Magnesia (nach bekannten Methoden) durch Behandlung dieser Laugen mit Kainit oder Carnallit nutzbar gemacht werden können.Finally it is of value and also new that the potash residue remaining in the final liquors, as well as the sulfuric magnesia (according to known methods) by treating these alkalis can be made usable with kainite or carnallite.
