Es ist bereits bekannt, Kieserit aus dem Rückstand der Kalirohsalzverarbeitung durch Flotation mit Hilfe von Sulfaten oder Sulfonaten von Fettsäuren oder Fettalkoholen oder Seifen abzutrennen. Diese flotative Abtrennung des Kieserits geschieht in gesättigten Salzlaugen.It is already known to use kieserite from the residue of crude potash processing by flotation of sulfates or sulfonates of fatty acids or Separate fatty alcohols or soaps. This flotative separation of the kieserite takes place in saturated Brines.
Ein besonderes technisches Problem ist die Gewinnung eines reinen Kieserits, der praktisch frei ist von Kochsalz und nur noch 'geringe Mengen Anhydrit enthält. A particular technical problem is the extraction a pure kieserite, which is practically free of table salt and only contains small amounts of anhydrite.
Es wurde nun erstmalig gefunden, daß die Herstellung eines praktisch chlorfreien Kieserits durch Flotation in Wasser mit ölsäure als Flotationsmittel möglich ist.It has now been found for the first time that the production of a practically chlorine-free kieserite by flotation is possible in water with oleic acid as a flotation agent.
Bei der kurzen Flotationsdauer des Kieserits geht das unerwünschte Steinsalz in Lösung, während sich der Kieserit nicht merklich löst. Bei der Flotation des Kieserits mit Oxystearinsäuresulfonat in Lauge wird beispielsweise ein Kieserit mit über 1 % Steinsalz erhalten, dagegen beträgt der Steinsalzgehalt bei einer flotativen Aufbereitung des Kieserits in Wasser mit ■ölsäure maximal nur 0,1%. Dieser reine, mit einer einmaligen Flotation gewonnene Kieserit kann in weiteren chemischen Umsetzungen, insbesondere Kreisprozessen, die chlorfrei gehalten werden müssen, eingesetzt werden, was für die verschiedenen technischen Prozesse, wie die Herstellung von Magnesia und Ammonsulfat, chemisch reinem Bittersalz und wasserfreiem Mg-Sulfat, einen technischen Fortschritt darstellt. With the short flotation time of the kieserite, the unwanted rock salt goes into solution, while itself the kieserite does not noticeably dissolve. During the flotation of the kieserite with oxystearic acid sulfonate in lye For example, a kieserite with more than 1% rock salt is obtained, while the rock salt content of one is flotative treatment of the kieserite in water with oleic acid only 0.1% maximum. This pure one, with one Kieserite obtained from a single flotation can be used in further chemical reactions, in particular cyclic processes, which must be kept chlorine-free, what are used for the various technical Processes such as the production of magnesia and ammonium sulfate, chemically pure Epsom salt and anhydrous Mg sulfate, represents a technical advance.
Die Verwendung von reinem Wasser als Traglauge bei der Flotation hat gegenüber den bisher verwendeten kalisalzhaltigen Laugen den weiteren Vorteil, daß keine K2 O-Verluste durch Austragen anhaftender Lauge mit Konzentrat und Rückstand entstehen.The use of pure water as hydrolysis liquor in flotation has the further advantage over the caustic potash solutions previously used that there are no K 2 O losses due to the discharge of adhering liquor with concentrate and residue.
Es ist überraschend, daß sich reine ölsäure in nicht verseiftem und nicht emulgiertem Zustand trotz ihrer Unlöslichkeit in Wasser als Flotationsmittel für diese Trennung verwenden läßt.It is surprising that pure oleic acid is not in saponified and not emulsified state despite their insolubility in water as a flotation agent for these Lets use separation.
Es ist weiterhin überraschend und von technischer Bedeutung, daß ölsäure nur in'Anwesenheit von Kieserit einen während des Schwlmmens beständigen Schaum bildet, der sofort nach Austritt aus der Schwimmaschine wieder zerfällt.It is also surprising and of technical importance that oleic acid can only be used in the presence of kieserite a foam that is stable during the flooding and which immediately emerges from the Swimming machine falls apart again.
Es hat sich jedoch als zweckmäßig gezeigt, eine möglichst chloT'arme Mischung von Flußwasser und eisenbikarbonathaltigem Grundwasser zu verwenden, da Eisenbikarbonat als Drücker' für. Anhydrit wirkt.However, it has been shown to be expedient to use a mixture of river water and water that is as low as possible in chlorine to use groundwater containing iron bicarbonate, as iron bicarbonate is used as a trigger for. Anhydrite works.
Der Unterschied im Anhydritgehalt des notierten Kieserits bei Einsatz von reinem Flußwasser gegenüber einem Flußwasser-Grundwasser-Gemisch ergibt sich aus dem nachstehenden Beispiel:The difference in the anhydrite content of the noted kieserite when using pure river water a river water-groundwater mixture results from the following example:
Bei Verwendung von reinem Flußwasser wird beieinem Anhydritgehalt des Rohkieserits von 5,6% ein Verfahren zur HerstellungIf pure river water is used, the raw gravel has an anhydrite content of 5.6% Method of manufacture

Anhydritgehalt des notierten Kieserits von 0,75%, bei Verwendung eines Grundwasser-Flußwasser-Gemisches von 0,35 % Anhydrit erzielt. Durch diesen Unterschied kommt der drückende Einfluß des Eisenbikarbonatgehaltes des Grundwassers zum Ausdruck.The anhydrite content of the noted kieserite was 0.75% Using a groundwater-river water mixture of 0.35% anhydrite achieved. Because of this difference the pressing influence of the iron bicarbonate content of the groundwater is expressed.
Weiter ist es erfindungsgemäß wesentlich für das Drücken des Anhydrits, den pH-Wert des Wassers nicht über 6,8 zu halten. Als weitere Drücker für Anhydrit haben sich Polyphosphate, wie beispielsweise die Handelsprodukte ' »Polyron« oder »Tripolyphosphat«, erwiesen.Further, it is not keeping inventively essential for pushing the anhydrite, the pH value of the water above 6.8. Polyphosphates, such as the commercial products “Polyron” or “Tripolyphosphate”, have proven to be a further trigger for anhydrite.
Der Einfluß des unterschiedlichen pH-Wertes auf das Drücken des Anhydrits ergibt sich aus nachstehendem Beispiel: 'The influence of the different p H -value to the pressing of the anhydrite obtained from the following example: '
Bei p^N 7,9 wird aus einem Kieserit mit 5,2%' Anhydrit als Ausgangsstoff ein Konzentrat mit 1,7% Anhydrit bei Flotation in Wasser mit ölsäure erhalten. Dagegen wind bei einem pHrWert von 6,8 ein Anhydritgehalt von nur 0,65 % erreicht.At p ^ N 7.9, a concentrate with 1.7% anhydrite is obtained from a kieserite with 5.2% anhydrite as the starting material during flotation in water with oleic acid. In contrast, a wind anhydrite reached of 0.65% at a p H of 6.8 rvalue.
Der Einfluß des Zusatzes von Polyphosphaten ergibt sich aus dem weiteren Beispiel :The influence of the addition of polyphosphates results from the following example:
Ohne Mitverwendungj von. Polyphosphat (bei pH 7,3) wird unter sonst gleichen Bedingungen ein Konzentrat mit 1,8% Anhydrit, bei gleichzeitiger Verwendung von »Polyron« in Mengen von rund 170 g/t Rohkieserit dagegen ein Anhydritgehalt von. 0,66%· erreicht. Bei Verwendung von etwa 65 g/t Tripolyphosphat wird unter gleichen Bedingungen der Anhydritgehalt auf 0,5 % gedrückt.Without using. Polyphosphate (at pH 7.3), a concentrate with 1.8% anhydrite under otherwise identical conditions, with simultaneous use of "Polyron" in amounts of about 170 g / t Rohkieserit other hand, a anhydrite of. 0.66% achieved. When using about 65 g / t tripolyphosphate, the anhydrite content is reduced to 0.5% under the same conditions.
Die ölsäure bietet gegenüber den bisher verwendeten KieseritfLotationsmitteln den weiteren Vorteil der besonderen Preiswürdigkeit. Außerdem genügen hier ölsäuremengen unter 100'g/t Rohkieserit, während die sonst bei flotativer Aufbereitung des Kieserits inCompared to the kieserite lotants used up to now, oleic acid offers the further advantage of special value for money. In addition, oleic acid quantities below 100 g / t of raw gravel are sufficient, while the otherwise with flotative processing of the kieserite in
