PATENTAMT.PATENT OFFICE.
Bei der Gewinnung von Rohkupfer aus schwefelhaltigen Kupfererzen und aus Kupfersteinen, welche wenig oder gar keine Kieselsäure enthalten, durch Einwirkung von Wind auf das schmelzflüssige Rohgut in Gegenwart basischer Körper, wie dies bei dem durch das Patent 153820 geschützten Verfahren geschieht, wird das vorhandene Eisen in Form einer leichtflüssigen, sich leicht einerseits von der Schlacke, andererseits von dem Rohmetall abtrennenden Verbindung von Schwefeleisen und Eisenoxyd erhalten. Es hat sich nun gezeigt, daß diese Verbindung im Schmelzofen als basisches Flußmittel zur Verschlackung der aus der Gangart des Erzes herrührenden Kieselsäure Verwendung finden kann. Die Eisenoxyd-Schwefelverbindung kann entweder als feste Masse oder im geschmolzenen Zustande in den Schmelzofen eingeführt werden.In the extraction of raw copper from sulfur-containing copper ores and from copper stones, which contain little or no silica, due to the action of wind on the molten raw material in the presence basic body, as happens in the process protected by patent 153820, the existing iron is in the form of a liquid, easily on the one hand from the slag, on the other hand from the raw metal separating compound of iron sulphide and iron oxide obtained. It has now been shown that this compound in the melting furnace as a basic flux for slagging those resulting from the gangue of the ore Silica can be used. The iron oxide-sulfur compound can either be introduced into the furnace as a solid mass or in the molten state.
Im Falle der Anwendung eines mit einem sauren Futter versehenen Herdofens empfiehlt es sich in den meisten Fällen, die Eisenoxyd- ' Schwefelverbindung im geschmolzenen Zustande zuzuführen, während bei dem Schmelzen des Erzes in einem Schachtofen die Eisenoxyd-Schwefelverbindung in festen Stücken zugeführt wird.Recommended in the case of using a hearth oven provided with an acidic lining in most cases it is the iron-oxide-sulfur compound in the molten state to supply, while the iron oxide-sulfur compound is being melted in a shaft furnace is fed in solid pieces.
