Description

Verfahren zur Aufbereitung von Steinsalz in lockeres Speisesalz. Zur Auflockerung und Erhöhung der Löslichkeit von bergmännisch gewonnenem Steinsalz sind schon verschiedene Verfahren bekannt. Nach diesen wird ein lockeres und leicht lösliches Salz entweder durch Ausfällen aus konzentrierter Chlornatriumlösung oder durch Trennung der feinen Kristalle von den gröberen des Steinsalzes durch Schlämmen in einer für Chlornatrium indifferenten Flüssigkeit von hohem spezifischen Gewicht erreicht.Process for processing rock salt into loose table salt. To the Loosening and increasing the solubility of rock salt extracted by mining various processes are already known. After this one becomes loose and easy soluble salt either by precipitation from concentrated sodium chloride solution or by separating the fine crystals from the coarser ones of the rock salt by sludge in a liquid of high specific gravity which is indifferent to sodium chloride achieved.

Es hat sich nun gezeigt, daß das so gewonnene Salz weiteren Mengen von gemahlenem Rohsalz zur Auflockerung beigemischt werden kann, wenn man darauf achtet, daß die Korngröße der zu mischenden Salze im wesentlichen die gleiche ist.It has now been shown that the salt obtained in this way can be used in more quantities of ground crude salt can be added to loosen up, if you want to ensure that the grain size of the salts to be mixed is essentially the same.

Noch günstiger ist die Wirkung, wenn man als Auflockerungssalz Chlornatrium verwendet, das durch Einrühren von konzentrierten Kochsalzlösungen in konzentrierte Lösungen von Chlorcalcium, Chlormagnesium oder Kaliendlaugen ausgefällt worden ist. Dieses gefällte Kochsalz zeichnet sich durch eine besonders feine, gleichmäßige Körnung aus, dem durch feine Absiebung des rohen Salzes Rechnung getragen werden muß.The effect is even more beneficial if sodium chloride is used as the loosening salt used by stirring concentrated saline solutions into concentrated Solutions of calcium chloride, magnesium chloride or potassium hydroxide solution has been precipitated. This precipitated table salt is particularly fine and even Grain size, which is taken into account by fine sieving of the raw salt got to.

Ein weiterer Vorteil dieses Lockerungsverfahrens besteht darin, daß infolge der staubtrockenen Beschaffenheit des Rohsalzes das zur Lockerung dienende, durch einen Schlämmprozeß oder durch Ausfällung erhaltene Salz keinen Trocknungsprozeß mehr durchzumachen braucht.Another advantage of this loosening method is that due to the dust-dry nature of the crude salt, the loosening salt obtained by a slurry process or by precipitation does not have a drying process needs to go through more.

PATENTANSPRUCH: Verfahren zur Aufbereitung von Steinsalz in lockeres Speisesalz, darin bestehend, daß man gemahlenes Steinsalz mit voluminösem Salz von im wesentlichen gleicher Körnung, das durch Trennung der feinen Kristalle von den gröberen des Steinsalzes durch Schlämmen in einer für Chlornatrium indifferenten Flüssigkeit von hohem spezifischen Gewicht oder durch Ausfällen aus konzentrierter Chlornatriumlösung erhältlich ist, vermischt. PATENT CLAIM: Process for processing rock salt into loose table salt, consisting in that ground rock salt with voluminous salt of essentially the same grain size, which is obtained by separating the fine crystals from the coarser ones of the rock salt by slurrying in a liquid of high specific gravity which is indifferent to sodium chloride or by precipitation from concentrated sodium chloride solution, mixed.
