Bei dem bisher gebräuchlichen Verfahren zur Herstellung von Aluminium durch Behandlung von Bauxit öder anderen geeigneten Aluminiumerzen ist es notwendig, den Bauxit 5 oder das sonst benutzte Mineral vor der Verarbeitung zu reinigen. Diese Reinigung bildet einen Prozeß für sich, der in besonderen Anlagen vorgenommen wird, worauf man die durch Reinigung des Bauxits erhaltene Tonerde zur Aluminiumherstellung verwendet.In the previously used process for the production of aluminum by treatment of bauxite or other suitable aluminum ores, it is necessary to use the bauxite 5 or the otherwise used mineral to be cleaned before processing. This purification forms a process of its own, which is carried out in special systems, whereupon the Alumina obtained by purifying the bauxite is used for aluminum production.
Diese Art des Arbeitens ist naturgemäß mitThis way of working is naturally with
beträchtlichen Unkosten verknüpft, Welche um so mehr ins Gewicht fallen, als sie durchassociated with considerable expenses, which are all the more important as they are carried through
. verwertbare Nebenprodukte nicht kompensiert werden können. Die Unkosten werden noch dadurch erhöht, daß die für gewisse Verfahren der Reinigung des Bauxits aufgewendete Wärme vollkommen verloren ist, da die Reinigungsanlagen vollständig von der Aluminiumherstellung getrennt sind.. usable by-products cannot be compensated. The expense will still be increased by the fact that the expended for certain processes of cleaning the bauxite Heat is completely lost because the cleaning equipment is entirely from aluminum production are separated.
Die Erfindung betrifft ein Verfahren zur Herstellung von Aluminium unter Anwendung von rohem Bauxit als Rohstoff, bei welchem die Reinigung des Bauxits gewissermaßen gleichzeitig, in einem Arbeitsgang, mit dem Umwandlungsprozeß, d. h. mit der Zersetzung der Tonerde zu Aluminium, erfolgt. Durch dieses Verfahren wird dem Verlust an Wärme vorgebeugt, die erforderliche Handarbeit be- ■ trächtlich eingeschränkt, die Zeitdauer der Fabrikation verkürzt; die Transportkosten und alle sonst mit der bisherigen Arbeitsweise verbundenen Kosten werden wesentlich vermindert. Dazu kommt noch eine weitere Verringerung der Gestehungskosten durch die Gewinnung verwertbarer Nebenprodukte.The invention relates to a method for producing aluminum using of raw bauxite as a raw material, in which the purification of the bauxite to a certain extent at the same time, in one operation, with the conversion process, d. H. with the decomposition the alumina to aluminum. This process eliminates the loss of heat prevented, the necessary manual work ■ considerably restricted, the duration of the Production shortened; the transport costs and all otherwise associated with the previous way of working Costs are significantly reduced. In addition, there is a further reduction in the production costs due to the extraction usable by-products.
Zur praktischen Ausübung des Verfahrens geht man auf die im Patent 204004 angegebene Weise vor. Man behandelt nämlich den rohen Bauxit im elektrischen Ofen mit einer Borverbindung und Kohle, um durch Abscheidung des Eisens und der Kieselsäure reinen geschmolzenen Bauxit zu erhalten.To practice the process, refer to that given in patent 204004 Way before. The raw bauxite is treated in an electric furnace with a boron compound and carbon in order to get through Separation of the iron and silica to obtain pure molten bauxite.
Die so erschmolzene gereinigte Tonerde wird, ohne sie vorher erkalten zu lassen, in einen anderen Teil des Ofens oder in einen zweiten Ofen abgezogen, wo sie nach den üblichen Verfahren zur Gewinnung von Aluminium weiterbehandelt wird.The cleaned clay that is melted in this way is turned into one without letting it cool down beforehand other part of the oven or peeled off in a second oven, where they are according to the usual Process for the production of aluminum is further treated.
Das vorliegende Verfahren der Herstellung von Aluminium unter direkter Verwendung von rohem Bauxit als Ausgangsmaterial, bei welchem die Reinigung des Bauxits in Verbindung und gewissermaßen gleichzeitig mit der Umwandlung der Tonerde in Aluminium erfolgt, ist hinsichtlich Einstandskosten den bislang gebräuchlichen Verfahren wesentlich überlegen. Abgesehen von den bereits angeführten Vorteilen des Verfahrens erhält man bei demselben als Nebenprodukt ein mit Bor legiertes Eisen von sehr beträchtlicher Härte, das für zahlreiche Zwecke verwendet werden kann. Auch kommt die geschmolzene und gereinigte Tonerde mit sehr hoher Temperatur in den zu ihrer Reduktion dienenden Ofen, wodurch an Wärmeaufwand und an Zeit wesentlich gespart wird.The present method of producing aluminum using direct use of raw bauxite as the starting material, in which the purification of the bauxite is related and takes place at the same time as the conversion of the alumina into aluminum, as it were, is the most expensive in terms of input costs Significantly superior to the methods commonly used up to now. Apart from those already mentioned Advantages of the process one obtains an iron alloyed with boron of very considerable hardness as a by-product, that can be used for numerous purposes. Also comes the melted and cleaned alumina at a very high temperature in the furnace used for its reduction, which saves a lot of heat and time.
