Description

Herstellung eines ockerartigen Farbkörpers aus Bleicherdelaugen In dem Patent 5 ¢ 1 6 13 ist ein Verfahren beschrieben, um aus Bleicherdelaugen das Eisen in verwertbarer und gut filtrierbarer Form unter gleichzeitiger Vermehrung des Tonerdegehaltes der Lauge abzuscheiden. Dies wird dort erreicht durch Behandlung der Lauge mit Ton oder Kaolin in gebranntem Zustände bei Siedehitze oder nahe dem Siedepunkte.Production of an ocher-like color body from bleaching earth lye In the patent 5 [1 6 1 3 ] a process is described in order to separate the iron from bleaching earth lye in usable and easily filterable form while increasing the alumina content of the lye at the same time. This is achieved there by treating the lye with clay or kaolin in a burned state at boiling point or near the boiling point.

Es wurde gefunden, daß alle dort angegebenen Vorteile schneller erreicht werden, wenn an Stelle von Ton oder Kaolin, die mit oder ohne Brennstoffzusatz zwischen 500 und 8oo° C geglüht worden waren, solcher Ton oder Kaolin angewendet wird, der mit oder ohne Brennstoffzusatz, aber mit Zusatz von Salzen der Alkalien oder alkalischen Erden, deren Säure in der Hitze vom Ton ausgetrieben wird, gebrannt wurde. Der Eintritt von Alkali oder Erdalkali in das Tonerdesilikat:nolekül bedingt diese beschleunigte Wirkung der Zersetzung. Während die Behandlung der Lauge nach Patent 541 6i3 eine Temperatur nahe dem Siedepunkte erheischt und durch mehrere Stunden fortgesetzt werden muß, genügt bei Anwendung eines so in der basenaustauschenden Wirkung gesteigerten Materials bereits eine Temperatur Von 4o bis 5o° C und kurze Rührdauer. Wird beispielsweise Kaolin mit Salz geglüht, so entweicht hierbei Salzsäure, die ihrer Menge nach genau dem Eintritt von -FäIlungsnatrium neben Tonerde in die Lauge entspricht, so daß mit Hinzuziehung dieser Salzsäure die absolute Anreicherung der- Lauge an Tonerde genau soweit getrieben werden kann wie bei Anwendung von gebranntem Ton oder Kaolin für sich.It has been found that all the advantages specified there are achieved more quickly if, instead of clay or kaolin, which had been calcined with or without the addition of fuel between 500 and 800 ° C., such clay or kaolin is used which, with or without the addition of fuel, but with the addition of salts of alkalis or alkaline earths, the acid of which is expelled from the clay in the heat. The entry of alkali or alkaline earth into the alumina silicate: nolekül causes this accelerated decomposition effect. While the treatment of the alkali according to Patent 541,613 requires a temperature close to the boiling point and has to be continued for several hours, when using a material with an increased base exchange effect, a temperature of 40 to 50 ° C. and a short stirring time are sufficient. If, for example, kaolin is annealed with salt, hydrochloric acid escapes, the amount of which corresponds exactly to the entry of -FäIlungsnatrium in addition to clay into the liquor, so that with the addition of this hydrochloric acid, the absolute enrichment of the liquor in clay can be driven exactly as far as in Applying baked clay or kaolin on its own.

Es ist bereits bekannt, durch einen solchen Zusatz zu den Schmelzen von Ton oder Kaolin eine höhere Austauschfähigkeit herbeizuführen. Es war jedoch nicht vorauszusehen, daß bei der Behandlung der Bleicherdelaugen mit solchen Schmelzen das Eisen dabei als ein ockerartiger Farbkörper sich ausscheidet. Auch ließ sich nicht voraussehen, daß neben dem Alkali auch die Tonerde in gleicher Weise in die Lauge eintritt.It is already known by such an addition to the melts to bring about a higher exchangeability of clay or kaolin. It was, however not foreseeable that in the treatment of the bleaching earth eyes with such melts the iron is precipitated as an ocher-like body of color. Also let himself do not foresee that, in addition to the alkali, the alumina will also enter the Lye enters.
