durch die Öffnungen c herauszutreten beginnt. Da der Deckel d mit seinem unteren Teil so weit herabreicht, dass er dann in das Salzbad eintaucht, ist damit der Einfüllschacht abgeschlossen. Die Schmelzflammen können daher nicht mehr durch den Einfüllschacht e entweichen, sondern treten durch die eine oder andere der Öffnungen c aus. Nunmehr wird das Schmelzgut in kleinen Mengen nach und nach, gegen die Schmelzflammen geschützt, durch den Einfüllschacht in das Salzbad eingebracht und durch die Öffnungen c mit Hilfe einer Krücke unterhalb des Schachtes in das Salz gerührt ; mit der Zeit sammelt sich nun im unteren Teil < /des Schmelzraumes eine.
Metallschichte an, während sich die in den Spänen usw. enthaltenen Metalloxyde mit dem geschmolzenen Salz verbinden und darüber lagern. Dadurch wird der Spiegel des geschmolzenen Salzes höher getrieben und das Salz samt den Rückständen teilweise zu den Öffnungen c hinausgedrückt. Wenn das geschmolzene Salz genügend Unreinigkeiten aufgenommen hat wird der Ofen gekippt und sein Inhalt durch die Öffnungen c entleert, wobei darauf zu achten ist, dass das Salz und das geschmolzene Metall möglichst getrennt gewonnen werden.
PATENT-ANSPRÜCHE :
1. Verfahren zur Wiedergewinnung von Leichtmetallen aus Spänen, Rückständen und Aschen durch Schmelzen dieser leichtmetallhaltigen Stoffe mit Salzen, dadurch gekennzeichnet, dass das Schmelzgut nach und nach in geringen Mengen in das Salzbad eingeführt wird.

begins to emerge through the openings c. Since the lower part of the cover d extends so far that it is then immersed in the salt bath, the filling shaft is closed off. The melting flames can therefore no longer escape through the feed chute e, but rather emerge through one or the other of the openings c. Now the melting material is gradually protected from the melt flames in small quantities, introduced into the salt bath through the filling shaft and stirred into the salt through the openings c with the aid of a crutch below the shaft; over time, one collects in the lower part </ of the melting chamber.
Metal layer, while the metal oxides contained in the chips etc. combine with the molten salt and deposit on top. As a result, the level of the molten salt is driven higher and the salt together with the residue is partially pushed out to the openings c. When the molten salt has absorbed enough impurities, the furnace is tilted and its contents emptied through the openings c, whereby it must be ensured that the salt and the molten metal are obtained as separately as possible.
PATENT CLAIMS:
1. A method for recovering light metals from chips, residues and ashes by melting these light metal-containing substances with salts, characterized in that the molten material is gradually introduced into the salt bath in small quantities.
