   Das Verfahren   zut Behandlung   von Schwefelerzen, wie der Blende, des Galenits, der zusammengesetzten   Sch\\, L1erze   von Zink und Blei, des   Schwefelântimons   u. s. w. nach der Niederschlagsmethodo besteht, wie bekannt, in dem Austreiben des Metalles aus der Schwefelverbindung durch ein anderes Metall, hauptsächlich durch Eisen. So einfach diese Reaktion theoretisch erscheint, so konnte sie in der Praxis lange Zeit nicht gelingen, insbesondere weil sie eine sehr hohe Temperatur verlangt und nur in sehr unvollkommener Weise durch-   führbar   ist.

   Es wurde von verschiedenen Seiten vorgeschlagen, zur Behebung dieser Nachteile   die     Schwefelerze   in einem Lösungsmittel aufzulösen, sodass die Wirkung des Fällungsmetalles 
 EMI1.2 
 die erforderliche Temperatur auf verhältnismässig niedere Grenzen zurückgeführt wird. Als   Lösungsmittel für die zu behandelnden Schwefelerze   und zwar ganz besonders für die   Hh'nde wurde   bereits   vorgeschlagcn, teils   ein geschmolzenes Gemisch von Metalloxyden. tails ein Sehwefelmnetall, insbesondere das Schwefeleisen. Die Anwendung von Metalloxyden   oder einem Schwefelmetall allem bietet bei der praktischen Durchführung Nachteile, sodass     dans gewünschte   Resultat nur teilweise erziett wurde.

   Insbesondere liessen die auf diese Weise erzielten Resultate zu wüschen übrig. wenn Blende zu behandeln war, denn bei der Ge-

   In der Mischung von   Schwefelmetallen   und Metalloxyde, welche das Lösungsmittel bildet, kann das Eisenoxyd auch durch Manganoxyd, Kalk, Magnesia, Zinkoxyd, gebrannten Dolomit (Ca 0,   go   0), Bariumoxyd oder durch irgend ein Oxyd der alkalischen Erden ersetzt werden. Wenn Mangan als Reaktionsmittel verwendet wird, ist es vorteilhaft, das Lösungsmittel aus Schwefelverbindungen und Oxyden des Mangans herzustellen. Wenn mehr oder weniger reiches Ferromangan verwendet wird, muss dem Lösungsmittel eine solche Menge Schwefel und Manganoxyd zugesetzt werden, welche dem in dem Eisen enthaltenen Mangan entspricht. 



   Die besondere Kategorie der   verwendbaren Lösungsmittel, welche   aus Schwefelmetallen und Oxyden des reagierenden Metalles gebildet werden, d. h. von Schwefel-und Oxyverbindungen des Metalles, welches das aus dem zu behandelnden   Schwefelerz   zu gewinnende Metall ersetzen soll, ermöglicht die unbegrenzte Verwendung eines Teiles des Schwefels aus dem flüssigen Rückstand und eines Teiles des Oxydes, welches beim Rösten desjenigen Teiles entsteht, der nicht als Schwefelmetall zur Verwendung gelangt. Auf diese Weise ergibt sich ein Kreislauf bei dem Verfahren.

1. Verfahren zur Gewinnung von Metallen ans Schwefelerzen durch Niederschlagsarbeit, wobei die Erze während der Reaktion durch   Zuschläge flüssig   erhalten worden, dadurch gekennzeichnet, dass als Zuschlag ein Gemisch von Schwefelmetallen und Metalloxyden verwendet wird.

 EMI1.1
 



   The process for the treatment of sulfur ores, such as blende, galena, composite ores of zinc and lead, sulfur antimony and the like. s. w. According to the method of precipitation, as is known, the metal is driven out of the sulfur compound by another metal, chiefly iron. As simple as this reaction appears theoretically, it has not been successful in practice for a long time, in particular because it requires a very high temperature and can only be carried out in a very imperfect manner.

   It has been proposed by various sides to eliminate these disadvantages, to dissolve the sulfur ores in a solvent, so that the action of the precipitated metal
 EMI1.2
 the required temperature is reduced to relatively low limits. A molten mixture of metal oxides has already been proposed as a solvent for the sulfur ores to be treated, and especially for the hands. tails a sulphurous metal, especially iron sulphide. The use of metal oxides or one sulfur metal in particular has disadvantages in practical implementation, so that the desired result was only partially achieved.

   In particular, the results obtained in this way left something to be desired. if aperture had to be treated, because

   In the mixture of sulfur metals and metal oxides which form the solvent, the iron oxide can also be replaced by manganese oxide, lime, magnesia, zinc oxide, burnt dolomite (Ca 0, go 0), barium oxide, or by any oxide of the alkaline earths. If manganese is used as the reactant, it is advantageous to prepare the solvent from sulfur compounds and oxides of manganese. If more or less rich ferromanganese is used, an amount of sulfur and manganese oxide must be added to the solvent which corresponds to the manganese contained in the iron.



   The particular category of solvents which can be used, which are formed from sulfur metals and oxides of the reacting metal; H. of sulfur and oxy compounds of the metal, which is to replace the metal to be recovered from the sulfur ore to be treated, enables the unlimited use of a part of the sulfur from the liquid residue and a part of the oxide which is formed during the roasting of that part which is not sulfur metal comes to use. In this way there is a cycle in the process.
