  Verfahren zur Gewinnung von metallischem Antimon aus seinen Legierungen mit anderen Metallen. 



   Das Verfahren beruht auf der Beobachtung, dass es beim Erhitzen derartiger, zweckmässig zerkleinerter Legierungen mit Schwefel möglich ist, daraus Antimon metallisch zu gewinnen und nur die 
 EMI1.1 
 äquivalent wählt. Es werden hiebei   überraschenderweise   nur die anderen Metalle an Schwefel gebunden während das Antimon nicht mit dem Schwefel in Verbindung tritt, sondern im Zustande des freien Metalls verbleibt, so dass eine praktisch quantitative Trennung möglich ist. 



   Beispiel : Eine Legierung, die etwa   40% Zinn, 40%'Kupfer, 0% Blei   und   10% Antimon ent-   hält, wird zerkleinert und mit einer den anwesenden Mengen von Zinn. Blei und Kupfer äquivalenten Menge Schwefel gemischt. Das Gemisch wird erhitzt und geht dabei in   flüssigen   Zustand   über.   wobei Zinn, Blei und Kupfer in ihre Sulfide übergeführt werden, während das gesamte Antimon in metallischem Zustande verbleibt. Es werden etwa   9-5%   Antimon in einer Reinheit von etwa   92  u zurückgewonnen.   



  Die Erhitzung kann in irgendeinem geeigneten Ofen erfolgen, der mit einer Abstichüffnung versehen ist. durch die man das geschmolzene Antimon abzieht, während die Sulfide im Ofen zurückbleiben. 



   Das gewonnene Antimon kann von den geringfügigen darin enthaltenen Verunreinigungen, insbesondere gelösten Anteilen der Schwefelverbindungen, in bekannter Weise befreit werden. Aus den Sulfiden werden Zinn, Blei und Kupfer in bekannter Weise gewonnen.

  Process for the extraction of metallic antimony from its alloys with other metals.



   The method is based on the observation that when such, appropriately comminuted alloys with sulfur are heated, it is possible to obtain metallic antimony and only the
 EMI1.1
 equivalent chooses. Surprisingly, only the other metals are bound to sulfur while the antimony does not come into contact with the sulfur, but remains in the state of the free metal, so that a practically quantitative separation is possible.



   Example: An alloy that contains about 40% tin, 40% copper, 0% lead and 10% antimony is crushed and mixed with the amount of tin present. Lead and copper equivalent amount of sulfur mixed. The mixture is heated and turns into a liquid state. tin, lead and copper are converted into their sulphides, while all of the antimony remains in a metallic state. About 9-5% antimony is recovered in a purity of about 92 µ.



  The heating can take place in any suitable oven which is provided with a tapping opening. which draws off the molten antimony while leaving the sulphides in the furnace.



   The antimony obtained can be freed from the minor impurities contained therein, in particular dissolved portions of the sulfur compounds, in a known manner. Tin, lead and copper are extracted from the sulphides in a known manner.

PATENT-ANSPRUCH : Verfahren zur Gewinnung von metallischem Antimon aus seinen Legierungen mit anderen Metallen, dadurch gekennzeichnet, dass die zweckmässig zerkleinerten Legierungen mit einer Menge Schwefel zum Schmelzen erhitzt werden, die derjenigen der in der Legierung ausser dem Antimon vorhandenen Metalle äquivalent ist, worauf das geschmolzene metallische Antimon von den gebildeten Sulfiden der anderen Metalle getrennt wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the production of metallic antimony from its alloys with other metals, characterized in that the appropriately comminuted alloys are heated to melt with an amount of sulfur which is equivalent to that of the metals present in the alloy in addition to the antimony, whereupon the molten metallic antimony of the formed sulfides of the other metals is separated. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
