Schichten wieder aufgenommen werden. Die fertigen Lösungen lässt man zweckmässig mit einem geringen Restgehalt an freier Säure ablaufen ; sie sind, da bei der vorliegenden Arbeitsweise der Kieselsäurerüekstand die Lage und Form des Ausgangsstoffes bei ält, technisch Ideselsäurefrei. Nach diesem Veifahren lassen sich auch bisher als unbrauchbar eLaeitete Tonarten gewinnbringend verarbeiten.
Beispiel : 100 t geglühte Ton werden in mehreren Metern Schichthöhe in einen Behälter mit doppeltem Boden eingestürzt. Zur Einleitung der Reaktion lässt man zunäcl st einen geringen Teil der erforderlichen Gesamtsäuremenge, zugleich mit Waschsäure eines vorhergehenden Aufschlusses, zweckmässig in vorgewärmtem Zustande, auf den Ton auflaufen und beschickt dann, nachdem der Behälter

Dies hatzur Folge, dass derweitaus grösste Teil der Gesamtsäuremenge,

Layers are resumed. The finished solutions are expediently allowed to run off with a small residual content of free acid; They are technically ideselic acid-free, since the silica residue in the present method of operation, the position and shape of the starting material in the case of old. According to this process, e-conductive keys that were previously unusable can also be processed profitably.
Example: 100 t of annealed clay are collapsed into a container with a double bottom at a layer height of several meters. To initiate the reaction, a small part of the total amount of acid required is allowed to run onto the clay at the same time as washing acid from a previous digestion, expediently in a preheated state, and then charged after the container
EMI2.1
Liquid level above the material to be digested achieves that the zone of maximum temperature in the feed gradually progresses downwards and rises to at least 105, advantageously to around 120, at the respective reaction point. As a result, by far the largest part of the total amount of acid,

In a similar way as described here for clay, kaolin, bauxite and the like can be used. a. to process.
