Description

Verarbeitung von Konverterstäuben, vorzüglich bestehend aus Oxydgemischen des Zinks, Zinns, Bleis und Kupfers Es ist bekannt, Oxydgemische von Zink, Zinn, Blei und Kupfer usw. mit Soda und keduktionsstoff zu verschmelzen.Processing of converter dust, especially consisting of oxide mixtures of zinc, tin, lead and copper It is known that oxide mixtures of zinc, tin, To fuse lead and copper etc. with soda and reducing agent.

Handelt es sich dabei um Produkte, welche zinnreich sind, so arbeitet das Verfahren unbefriedigend, indem die erschmolzene Zinnlegierung in hohem Maße Zink enthält.If these are products that are rich in tin, work the process unsatisfactory by removing the molten tin alloy to a large extent Contains zinc.

Die Erfindung betrifft die Anwendung dieses Verfahrens bei Behandlung von Konverterstäuben, welche bei Oxyden des Zinks, Bleis und Kupfers in beträchtlichem Maße "Zinnsäure enthalten.The invention relates to the use of this method in treatment of converter dusts, which are considerable with oxides of zinc, lead and copper Measures "contain stannic acid.

Es hat sich überraschenderweise gezeigt, daß bei der Behandlung dieser Produkte nach dem an sich bekannten Verfahren eine Zinnlegierung erhalten wird, welches fast frei von Zink ist.It has surprisingly been found that in the treatment of this A tin alloy is obtained products by the process known per se, which is almost free of zinc.

Dieser Erfolg ist darauf zurückzuführen, daß es sich bei Konverterstäuben, im Gegensatz z. B. zu Zinnaschen, um reine oxydische Produkte handelt, die außerdem in außerordentlich feiner Verteilung vorliegen, so daß bei der Behandlung die Zinkoxydentfernung vor sich geht, bevor die Zinnlegierung gebildet wird. Nachstehend ist ein Ausführungsbeispiel des Verfahrens gegeben: Ein Konverterstaub mit 2 5 % Zinn, 180/a Blei, 309o Zink wird mit 25°o Soda und 301 Kohle gemischt. Die Mischung wird in einen Flammofen eingebracht und entsprechend erhitzt.This success is due to the fact that converter dusts, in contrast to z. B. to tin ash, are pure oxidic products, which are also present in extremely fine distribution, so that the zinc oxide removal takes place during the treatment before the tin alloy is formed. An exemplary embodiment of the method is given below: A converter dust with 25% tin, 180% lead, 3090 zinc is mixed with 25% soda and 301 carbon. The mixture is placed in a furnace and heated accordingly.

Kurz nach Eindringen erfolgt die Ausscheidung des Zinkoxyds, welche außerordentlich schnell beendigt ist. Nach einer Behandlung von ungefähr 5 Stunden ist die Charge fertig und eine von Zink fast freie Blei-Zinn-Legierung gebildet, die, falls Kupfer anwesend, auch dieses enthält.Shortly after penetration, the zinc oxide is excreted, which is completed extremely quickly. After about 5 hours of treatment is the batch ready and a lead-tin alloy almost free of zinc is formed, which, if copper is present, also contains this.
