Vorliegende Erfindung betrifft die Herstellung von Eisenmangan unter gleichzeitiger
Gewinnung von Oxyden der Alkalien oder Erdalkalien im elektrischen Ofen.
Das Verfahren besteht darin, daß zunächst Mangan- und Eisenoxyd enthaltendes Manganerz
durch unmittelbare Wirkung des Schwefelalkalis, dessen Oxyd man erzeugen will, oder
mittels des entsprechenden Sulfats in Gegenwart von Kohle verschlackt wird. Hierbei
wird ein schmelzflüssiges Gemisch der Oxyde von Mangan und Eisen und des Alkali- oder
Erdalkali-Oxyds neben schwefliger Säure erhalten. The present invention relates to the production of iron manganese with simultaneous recovery of oxides of alkalis or alkaline earths in an electric furnace.
The process consists in that manganese ore containing manganese and iron oxide is initially slagged by the direct action of the sulfur alkali whose oxide is to be produced, or by means of the corresponding sulfate in the presence of coal. This gives a molten mixture of the oxides of manganese and iron and of the alkali or alkaline earth oxide in addition to sulphurous acid.
In einem zweiten Arbeitsgang, der sich im elektrischen Ofen vollzieht, reduziert man die erhaltene Schmelze in Gegenwart von nur so viel Kohle, daß diese zur Reduktion des Mangans und Eisens hinreicht, aber nicht genügt, um das Alkali- oder Erdalkalimetall frei zu machen oder in eine Kohlenstoffverbindung zu verwandeln.In a second step, which takes place in the electric furnace, you reduce the melt obtained in the presence of only so much coal that it can be reduced of manganese and iron is sufficient, but not sufficient, to form the alkali or alkaline earth metal to set free or to turn into a carbon compound.
Um das neue Verfahren klarer darzulegen, soll an einem Ausführungsbeispiel die gleichzeitige Gewinnung von Eisenmangan und Baryumoxyd erläutert werden. Hierbei ist das Eisenmangan als ein Doppelcarbid von Eisen und Mangan aufzufassen; vgl. Compt. rend. Band" 128, Seite 209/11.In order to explain the new method more clearly, the simultaneous Extraction of iron manganese and barium oxide are explained. Here, the iron manganese is a double carbide of To understand iron and manganese; see Compt. rend. Volume "128, page 209/11.
Man bringt z. B. in einen elektrischen Ofen ein Gemisch von Manganerz, Baryumsulfat und Kohle, um die Doppeloxyde von Eisenbaryum und Manganbaryum nach folgender Formel zu bilden:One brings z. B. in an electric furnace a mixture of manganese ore, barium sulfate and coal to form the double oxides of iron barium and manganese baryum according to the following Form formula:
ΖΜηΟ,ΒαΟ + 2Fe3O\BaO +
5 SO2+ 9 CO. ΖΜηΟ, ΒαΟ + 2Fe 3 O \ BaO +
5 SO 2 + 9 CO.
Man bewirkt dann die Reduktion in einem anderen elektrischen Ofen nach der Formel:The reduction is then effected in another electric furnace according to the formula:
3MwO, BaO + 2Fe3O4, BaO + 14C =
(Mn3C+2Fe3C) + SBaO + 11CO.3MwO, BaO + 2Fe 3 O 4 , BaO + 14C =
(Mn 3 C + 2Fe 3 C) + SBaO + 11CO.
Die Schmelze wird mit kochendem Wasser behandelt; durch Kristallisation wird das Baryumoxyd im Zustande des Hydrats aus der Lauge abgeschieden.The melt is treated with boiling water; through crystallization that becomes Barium oxide deposited from the liquor in the state of hydrate.
Will man Natriumoxyd oder ein ähnliches flüchtiges Oxyd herstellen, so benutzt man bei der ersten Stufe einen Muffelofen mit Magnesiaauskleidung und verwendet an Stelle des Sulfats und Kohle das entsprechende Sulfid. Die Reaktion spielt sich dann nach folgender Formel ab:·If you want to produce sodium oxide or a similar volatile oxide, you use it at the first stage a muffle furnace with a magnesia lining and used in place of the sulphate and coal the corresponding sulphide. The reaction then plays out the following formula:
3 (MnO2 + Fe2O3) + Na2S= (Mn30\ 2Fe3O4J + Na2O + SO2. 3 (MnO 2 + Fe 2 O 3 ) + Na 2 S = (Mn 3 0 \ 2Fe 3 O 4 I + Na 2 O + SO 2 .
Diese zuletzt genannte Reaktion ist exothermisch und gelingt in einem gewöhnlichen Ofen.This last-mentioned reaction is exothermic and takes place in an ordinary way Oven.
Die elektrische Reduktion geht nach folgender Gleichung vor sich:The electrical reduction takes place according to the following equation:
Mw3O4, 2Fe3O4 -f ISC =Mw 3 O 4 , 2Fe 3 O 4 -f ISC =
.■■.-■ .-.- ■ (Mn3C + 2 Fe3C) + 12CO.. ■■ .- ■.-.- ■ (Mn 3 C + 2 Fe 3 C) + 12CO.
Bei diesen Arbeiten darf die Stromdichte 60 bis 80 Ampere pro Quadratzentimeter des Elektrodenquerschnittes nicht übersteigen.During this work, the current density must be 60 to 80 amperes per square centimeter of the Do not exceed the electrode cross-section.
Erzeugt man im elektrischen Ofen Eisenmangan gleichzeitig mit Natriumoxyd, so verflüchtigt sich» dieses Oxyd und wird in einer Niederschlaeskammer, in welche man Wasserdampf einläßt, wiedergewonnen. Die bei der ersten Arbeitsstufe auftretende schweflige Säure kann man zur Bildung von Schwefelsäure ausnutzen.If iron manganese is produced in an electric furnace at the same time as sodium oxide, so this oxide evaporates and becomes in a deposition chamber, in which one Lets in water vapor, recovered. The sulphurous that occurs in the first stage of work Acid can be used to form sulfuric acid.
Selbstverständlich bezieht sich das im vorhergehenden über Baryumoxyd und Natriumoxyd Ausgeführte auch auf die Oxyde der anderen Alkalien und Erdalkalien.Of course, the above refers to barium oxide and sodium oxide Executed also on the oxides of the other alkalis and alkaline earths.
Die Arbeiten müssen in dicht verschlossenen Öfen vorgenommen werden.The work must be carried out in tightly closed ovens.
