Description

Enteisenen von Kieselgur Es sind schon viele Versuche unternommen, Kieselgur zu enteisenen, doch hat keines dieser Verfahren praktische Bedeutung erlangt.De-ironing of diatomite Many attempts have been made to To de-iron diatomaceous earth, but none of these processes has gained practical importance.

Nach vorliegender Erfindung wird die rohe Kieselgur vor dem Calcinieren zunächst mit wäßrigen Lösungen der Alkalien, Alkalicarmonate, des Ammoniaks oder kohiensauren Ammoniaks oder mit Gemischen dieser behandelt und läßt sich darauf bedeutend leichter durch Säuren enteisenen als ohne diese Vorbehandlung. Enthält die rohe Kieselgur genügende Mengen organischer Substanzen, so geht bei der Extraktion mit Alkalien usw. ein Teil der organischeu Substanz in Lösung und bildet eine als Beize oder als Farbstoff verwendbare Flüssigkeit, die gegebenenfalls eingedampft und in trockene Form umgewandelt wird. Aus der vorbehandelten Kieselgur läßt sich das Eisen viel leichter durch Säuren extrahieren als aus der nicht vorbehandelten, und die Gur gibt dann, gegebenenfalls nach dem Rösten, ein weißes oder rosa gefärbtes Produkt.According to the present invention, the raw diatomaceous earth is pre-calcined initially with aqueous solutions of alkalis, alkali metal carbons, ammonia or Carbonate of ammonia or with mixtures of these treated and can be placed on it It is significantly easier to de-iron with acids than without this pretreatment. Contains the raw diatomaceous earth sufficient amounts of organic substances, so goes with the extraction with alkalis, etc., a part of the organic matter in solution and forms an as Mordant or liquid which can be used as a dye and which may be evaporated and is converted to dry form. From the pretreated kieselguhr can the iron can be extracted much more easily by acids than from the non-pretreated one, and the Gur then gives a white or pink color, if necessary after roasting Product.
