Description

Restlose Gewinnung des Kupfers aus eisenhaltigen Kupferschlacken. Bei der Kupferraffination und dem Kupferverblasen fällt eine Schlacke, die 25 und mehr Prozent Kupfer enthält. Das darin enthaltene Kupfer wird durch Verschmelzen im Rundofen, Wassermantelofen, als Schwarzkupfer wieder erhalten. Dabei bleibt eine Schlacke zurück, die meist noch o,8 bis z Prozent Kupfer enthält, in den seltensten Fällen nur o,5 Prozent. Dies in der Schlacke verbleibende Kupfer geht verloren, da,,#es nicht mehr rationell herausgewonnen werden kann.Complete extraction of copper from iron-containing copper slag. During copper refining and copper blowing, a slag that contains 25 percent or more of copper falls. The copper contained in it is obtained again as black copper by melting in a round furnace, water jacket furnace. A slag remains, which usually still contains 0.8 to z percent copper, in the rarest cases only 0.5 percent. The copper remaining in the slag is lost because it can no longer be extracted efficiently.

Dieser Nachteil wird gemäß der Erfindung dadurch beseitigt, daß man im Schachtofen den Prozeß so ausführt, daß das in der Schlacke enthaltene Eisen mit reduziert wird. Hierdurch wird alles in der Schlacke enthaltene Kupfer als der leichter reduzierbare Bestandteil mit dem Eisen restlos herausgeschmolzen, so daß man eine Schlacke erhält, die vollständig frei von Kupfer ist.This disadvantage is eliminated according to the invention in that one carries out the process in the shaft furnace in such a way that the iron contained in the slag with is reduced. This will make all the copper contained in the slag as the more easily reducible constituent melted out completely with the iron, so that a slag is obtained which is completely free of copper.

Es ist also möglich, auf diese Weise große Mengen Kupfer, die bisher mit der sogenannten absetzbaren Schlacke verloren gingen, zurückzugewinnen. In der oben angegebenen Arbeitsweise liegt somit eine wesentliche Verbilligung und größere Wirtschaftlichkeit des Kupferprozesses.So it is possible to use this method to produce large amounts of copper that were previously available lost with the so-called settable slag. In the The method of operation indicated above is therefore a substantial reduction in price and greater Economics of the copper process.

Das neue Verfahren läßt sich mit Hilfe eines entsprechenden Kokssatzes mit jeder beliebigen kupferhaltigen Schlacke durchführen. Das anfallende kupferhaltige Eisen wird dem Konverter beim Verblasen von Schwarzkupfer, Messing usw. wieder zugeführt. Das Eisen verbrennt hierbei unter Wärmeerzeugung zu Fe0 und FezO" während das Kupfer zum größten Teil abgeschieden wird. Aus der in dieser Weise gebildeten kupferhaltigen Schlacke wird dann im Rundofen das Kupfer samt dem Eisen reduziert.The new process can be carried out with the help of an appropriate coke rate perform with any copper-containing slag. The resulting copper-containing Iron is returned to the converter when black copper, brass, etc. are blown. The iron burns with heat generation to FeO and FezO "while the copper for the most part is deposited. From the copper-containing one formed in this way Slag is then reduced in the round furnace, the copper and the iron.
