   PATENT-ANSPRÜCHE : 
1. Verfahren zum Rösten oder Sintern von feinzerteilten Erzen, die entweder brennbare Bestandteile enthalten oder denen   feinvert. eilter Brennstoff beigemischt wurde. dadurch   gekennzeichnet. dass die Reaktion durch Entzünden der Beschickung am oberen oder unteren Ende eingeleitet wird, während am entgegengesetzten Ende kalte oder heisse Luft mit oder ohne Beigabe von 
 EMI3.2 
   Stelle   austreten, wo die Reaktion begonnen hat.

 A sintering of the material occurs on the surface and propagates downwards through the upper part of the charge, while then in the second stage the further air supplied causes the second sintering reaction from bottom to top through the still unsintered part of the charge.



   Here, too, there is no restriction to the specially named substances. The procedure
 EMI3.1
 has been.



   PATENT CLAIMS:
1. Process for roasting or sintering finely divided ores that either contain combustible components or those finely divided. hurried fuel was added. characterized. that the reaction is initiated by igniting the charge at the top or bottom, while at the opposite end cold or hot air with or without the addition of
 EMI3.2
   Exiting the point where the reaction started.

2. Abänderung des Verfahrens nach Anspruch I. dadurch gekennzeichnet, dass sobald die Erhitzungszone das Ende der Bes hickung erreicht hat. durch fortgesetzte Luft-und nasdurch- EMI3.3 3. Abänderung des Verfahrens nach Anspruch 2, dadurch gekennzeichnet. dass gleichzeitig und im gleichen Sinne mit dem Röstvorgang nach erfolgtem Schmelzen der Oberfläche eine nach unten forschreitende Sinterreaktion eingeleitet wird. während - sobald die Erhitzungszone das untere Ende erreicht-eine von unten nach oben verlaufende Sinterreaktion stattfindet. 2. Modification of the method according to claim I. characterized in that as soon as the heating zone has reached the end of the Bes hickung. through continued air and nasal EMI3.3 3. Modification of the method according to claim 2, characterized. that at the same time and in the same sense as the roasting process, after the surface has melted, a sintering reaction proceeding downwards is initiated. while - as soon as the heating zone reaches the lower end - a sintering reaction proceeding from bottom to top takes place.
