Description
Verfahren zur Verarbeitung von Metalloxyden, Aschen und Kratzen auf Metall. Eine weitere Ausbildungsform des Verfahrens nach dem Hauptpatent ist Gegenstand der vorliegenden Erfindung durch Anwendung bei der Brikettierung von Metalloxyden, Aschen und Kratzen, die auf regulinisches Metall verarbeitet werden sollen.Process for processing metal oxides, ashes and scraping on Metal. Another embodiment of the process according to the main patent is the subject matter the present invention by application in the briquetting of metal oxides, Ashes and scrapes to be processed on regular metal.
Die Anwendung erstreckt sich sowohl auf Oxyde der niedrig- als auch: der hochschmelzenden Metallgruppen. Insbesondere die ersteren sind für die Industrie von Wichtigkeit geworden, seitdem durch das Verblasen von. Messing und Bronzen deren leicht oxydierbareKomponenten, wie Zink, Zinn u. a., in großen Mengen in oxydischer Form anfallen.The application extends to oxides of the low as well as: of the refractory metal groups. The former in particular are for industry has since become of importance through the fading of. Brass and bronzes of theirs easily oxidizable components such as zinc, tin and others, in large amounts in oxidic Form.
Es wurde gefunden, däß die nach; dem Hauptpatent an sich bekannten Zusatzstoffe bei der Verwendlung des hier in Rede stehenden Verfahrens bei der Reduktion der Oxyde eine günstige Kontaktwirkung zwischen diesen und dem Reduktionsmittel ausüben, welche die Reduktionsarbeit nicht nur erleichtert, sondern auch wesentlich beschleunigt. Weiterhin tritt nach bereits erfolgter Reduktion auch noch sofort eine Schutzwirkung der gebildeten Metallteilchen oder Tropfen ein, indem diese im Sinne des Hauptpatents vor Wiederoxydation oder Abbrand z. B. durch die Fenerungsgase erfolgreich geschützt werden.It was found that the after; the main patent known per se Additives when the process in question is used in the reduction the oxides have a favorable contact effect between them and the reducing agent exercise, which not only facilitates the reduction work, but also significantly accelerated. Furthermore, it also occurs immediately after the reduction has already taken place a protective effect of the metal particles or droplets formed by placing them in the Meaning of the main patent before reoxidation or burn-off z. B. by the Fenerungsgase be successfully protected.
Diese günstige Kontaktwirkung konnte auch besonders bei den schwerer reduzierbaren Oxyden, z. B. des Chroms, Wolframs u. a., vorteilhaft festgestellt werden. Bei der Ausübung des Verfahrens kann man sowohl die Zusatzstoffe und das Reduktionsmittel als an sich getrennte Körper verwenden als auch solche Stoffe wählen, die als chemische Verbindung beide Körper gleichzeitig enthalten und erst in der Wärme Reduktions- und Flußmittel abspalten, wie z. B. -die Verbindungen des Zyans mit den Metallen der Erdalkalien oder diese als Doppelverbindungen mit z. B. Bor und Fluor u. a.This favorable contact effect could also be especially with the heavier ones reducible oxides, e.g. B. of chromium, tungsten and others will. When performing the procedure one can use both the additives and the Use reducing agents as per se separate bodies as well as choose such substances, which, as a chemical compound, contain both bodies at the same time and only in the Eliminate heat reducing agent and flux, such as. B. -the compounds of cyan with the metals of the alkaline earths or these as double compounds with z. B. boron and fluorine et al.
Ausführungsbeispiele. i. Für die Umarbeitung von i ooo kg Messingasche werden der Masse außer der für die Reduktion erforderlichen Kohle etwa i Prozent = io kg entwässerter Borax einverleibt und das Ganze nach genügender Durchmischung der Brikettierung unterworfen.Embodiments. i. For the processing of 100 kg of brass ash In addition to the coal required for the reduction, the mass becomes about 1 percent = 10 kg of dehydrated borax incorporated and the whole thing after sufficient mixing subjected to briquetting.
a. i ooo kg von Neusilber- oder sonstigen Nickellegierungen herstammenife Metallasche und -kratze enthaften nach Zugabe der erforderlichen Reduktionskohle den Zusatz von 2o kg kalzinierten Natriumkarbonats, worauf wie oben die Brikettierung erfolgt.a. i ooo kg come from nickel silver or other nickel alloys Metal ash and scrap become detached after adding the required reducing carbon the addition of 20 kg of calcined sodium carbonate, followed by briquetting as above he follows.
