    Verfahren zur IIerstelluM von MagucsiummetaM.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Das Verfahren ist auf die im   vorstehenden beschriebenen Ausführungsformen nieht beschräukt.   



  So kann z. B. an Stelle von Kohle als Reduktionsmittel ein kohlenstoffhaltiges Gas oder ein Kohlenwasserstoff   wie Methan   angewandt werden. Der Schmelzofen und der Kondensator sollen   möglichst   frei von Luftsauerstoff sein. Am besten arbeitet man in neutraler oder reduzierender Atmosphäre bei geringem Unterdruck. Das   magnesiumhaltige Gestein kann   mit dem Reduktionsmittel vermischt oder brikettiert werden. Die Briketts können wenigsten, zum Teil als Widerstand für den Durchgang des elektrischen Stromes dienen.

   An Stelle des Drehrohrofens kann auch ein anderer Ofentyp benutzt werden. in welchem es   möglich   ist, das Material gut   durchzurütteln   und gleichzeitig die Temperatur über dem 
 EMI2.1 
   magnesiumhaltige Gesteinsarten Verwendung   finden, wie Sulfide, Chloride u. dgl. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Magnesiummetall durch Reduktion oxydischer Magnesiumverbindungen bei Temperaturen, bei welchen das Magnesium in Form von Dampf entsteht, der kondensiert wird, dadurch gekennzeichnet, dass die einzelnen Teilchen des Kondensates durch mechanische Behandlung, wie z. B. durch Reiben,   Schütteln   od. dgl., zu massivem Magnesiummetall vereinigt werden.

 <Desc / Clms Page number 2>

 



   The method is not limited to the embodiments described above.



  So z. B. instead of coal as a reducing agent, a carbon-containing gas or a hydrocarbon such as methane can be used. The melting furnace and the condenser should be as free from atmospheric oxygen as possible. It is best to work in a neutral or reducing atmosphere with a slight negative pressure. The magnesium-containing rock can be mixed with the reducing agent or briquetted. At least some of the briquettes can serve as a resistance for the passage of the electric current.

   Another type of furnace can be used instead of the rotary kiln. in which it is possible to shake the material well while keeping the temperature above the
 EMI2.1
   Magnesium-containing rock types are used, such as sulfides, chlorides and the like. like



   PATENT CLAIMS:
1. A process for the production of magnesium metal by reducing oxidic magnesium compounds at temperatures at which the magnesium arises in the form of steam which is condensed, characterized in that the individual particles of the condensate by mechanical treatment, such as. B. by rubbing, shaking od. Like., Can be combined into solid magnesium metal.
