PATENTAMT.PATENT OFFICE.
Es ist bekannt, in manganhaltigen Eisenerzen zwecks Gewinnung hochprozentigen Ferromangans das Verhältnis des Mangans zum Eisen dadurch zu verbessern, daß die Erze zunächst in geröstetem oder ungeröstetem Zustande mit einem gasförmigen Reduktionsmittel (Wasserstoff, Kohlenoxyd usw.) derartig behandelt werden, daß im wesentlichen nur das Eisen, nicht aber auch das Mangan zu Metall reduziert wird, worauf das Eisen auf magnetischem Wege vom Mangan getrennt wird. Diese Art der Trennung hat aber nur dann Aussicht auf Erfolg, wenn es sich um die Verarbeitung solcher Erze han-It is known to use high-percentage in manganese-containing iron ores for the purpose of extraction Ferromanganese to improve the ratio of manganese to iron in that the First ores in a roasted or unroasted state with a gaseous reducing agent (Hydrogen, carbon dioxide, etc.) are treated in such a way that essentially only the iron, but not that too Manganese is reduced to metal, whereupon the iron is magnetically removed from the manganese is separated. This kind of separation only has a chance of success if it does are concerned with the processing of such ores
*5 delt, die aus einem Gemisch zweier Erze, einem nicht reduzierbaren hochwertigen, d. h. manganreichen Erz und einem reduzierbaren, minderwertigen, d. h. eisenreichen Erz, bestehen. Die magnetische Trennung führt aber dann nicht zum Ziele, wenn das zu verarbeitende Erz im wesentlichen einheitlicher Natur ist, wie es allgemein und insbesondere auch bei den heimischen manganhaltigen Eisenerzen (Siegerländer Eisenspat) der Fall ist. Es hat sich bei solchen Erzen gezeigt, daß sie nach Behandlung mit Reduktionsgasen selbst in feingepulvertem Zustande in ihrer ganzen Masse gleichmäßig vom Magneten angezogen werden. Der Grund hierfür ist wohl in der innigen Verbindung (festen Lösung) zu suchen, in welcher sich Mangan und Eisen im ursprünglichen Erz befinden. Um nun bei den genannten Erzen trotzdem eine Trennung des Eisens vom Mangan zu erzielen, werden die in der angegebenen Weise mit Reduktionsgasen behandelten Erze erfindungsgemäß im gleichen Ofen, in dem die Reduktion vorgenommen wurde, oder in einem anderen Ofen, nötigenfalls unter Zugabe von Schlackenbildnern, niedergeschmolzen, bei welchem Vorgang fast alles Mangan in die Schlacke geht, die dann mit den üblichen Zuschlägen im Hochofen oder auf irgendeine andere Weise auf Ferromangan weiterverarbeitet wird, während das geschmolzene Eisen in gewohnter Weise fertiggemacht wird.* 5 delt, which consists of a mixture of two ores, one irreducible high quality, d. H. manganese-rich ore and a reducible, inferior, d. H. iron-rich ore. The magnetic separation does not lead to the goal if that is to be processed Ore is essentially of a uniform nature, as it is generally and especially also with the domestic manganese-containing iron ores (Siegerland iron spar) is the case. It has such ores have shown that they are after Treatment with reducing gases even in a finely powdered state in their entirety Mass are attracted evenly by the magnet. The reason for this is probably in the to look for an intimate connection (solid solution) in which manganese and iron are in the original Ore are located. In order to still separate the To achieve iron from manganese, this is done in the specified manner with reducing gases treated ores according to the invention in the same furnace in which the reduction was carried out or in another furnace, if necessary with the addition of slag forming agents, melted down, during which process almost all of the manganese goes into the slag, which then with the usual surcharges in the blast furnace or in some other way Ferromanganese is processed further, while the melted iron in the usual way is made ready.
