Description

Verfahren zur Entzinkung von Bleischlacken, Muffelrückständen, armen Zinkerzen, zinkhaltigen Kiesabbränden usw. Es ist bekannt, Agglomerate bzw. Brikette aus Zink enthaltenden Materialien und Eisenerz im Schachtofen zu verhütten; es sind ferner Brikette verwandt worden, welche aus Zink enthaltenden Materialien, Zuschlägen und Reduktionsstoff zusammengesetzt sind: es ist ferner bekannt, bei der Verhüttung zinkhaltiger Materialien die Erze in Mischung mit Zuschlägen nach bekannten Verfahren vorzubereiten und zu bearbeiten.Process for dezincification of lead slag, muffle residues, poor Zinc ores, zinc-containing gravel burns, etc. It is known to have agglomerates or briquettes smelting materials containing zinc and iron ore in a shaft furnace; there are Furthermore, briquettes have been used, which are made of zinc-containing materials, aggregates and reducing agent are composed: it is also known in smelting zinc-containing materials the ores mixed with aggregates according to known methods prepare and edit.

Diesen bekannten Verfahren gegenüber unterscheidet sich die Erfindung dadurch, daß Brikette aus Zink enthaltenden Materialien und Zuschlägen ohne Reduktionsstoff verwandt werden, bei denen das Verhältnis der Zinkmaterialien und der Zuschläge so gewählt ist, daß ein hochschmelzbares Produkt vom ungefähren Charakter der Singulosilikate entsteht.The invention differs from these known methods in that briquette made of zinc-containing materials and aggregates without reducing agent are used in which the ratio of zinc materials and aggregates is chosen so that a high-melting product of the approximate character of the singulosilicates arises.

Im folgenden ist beispielsweise die Z_usamrnensetzung eines Möllers gegeben, aus dein die für das vorliegende Verfahren bestimmten Agglomerate oder Brikette gebildet sein können: 2; Prozent IIuffelrückstände, - zinkhaltige Abbrände, 2; - Bleischlacke, 20 - basischer Zuschlag aus Kalk und Magnesia im Verhältnis von i : i. Aus einem solchen Möller werden Agglornerate oder Brikette hergestellt und mit der erforderlichen Menge Reduktionsmaterial in einem normalen Gebläseschachtofen verarbeitet.In the following, for example, the composition of a Möllers is given, from which the agglomerates or briquettes intended for the present process can be formed: 2; Percent of muffle residues, - zinc-containing burns, 2; - lead slag, 20 - basic aggregate from lime and magnesia in the ratio of i: i. Agglomerates or briquettes are produced from such a Möller and processed with the required amount of reducing material in a normal blower shaft furnace.

Auf Grund des hohen Schmelzpunktes gehen die Agglomerate chemisch fast unverändert in die unterste Zone mit der höchsten Temperatur, wo sie dann erst zur Schmelzung gelangen. Die Folge davon ist, daß die Zinkreduktion, d. h. die Freilegung der das Zink enthaltenden Materialien für den Angriff .des Reduktionsmaterials plötzlich und unter den günstigsten Bedingungen. d. h. bei Weißglut, stattfindet. Die Reduktion ist unter diesen Umständen so elementar, daß nicht nur das Zink fast quantitativ, sondern sogar die in der Charge enthaltenen sonstigen Metalle, wie Eisen, Nickel, Kupfer, Kobalt, Silber, Gold usw., reduziert werden, während Zink und Blei fast restlos mit den Gasen entweichen.Due to the high melting point, the agglomerates go chemically almost unchanged in the lowest zone with the highest temperature, where they only then get to melt. The consequence of this is that the zinc reduction, i.e. H. the exposure of the zinc-containing materials for attack .the reducing material suddenly and under the most favorable conditions. d. H. at white heat, takes place. The reduction is so elementary under these circumstances that not only the zinc is almost quantitative, but even the other metals contained in the batch, such as iron, nickel, Copper, cobalt, silver, gold, etc., are reduced, while zinc and lead are almost reduced escape completely with the gases.

Das Verfahren kann in einem einfachen Schachtofen mit einfacher Düsenreihe durchgeführt werden und bedeutet einen außerordentlich großen wirtschaftlichen Fortschritt.'The process can be carried out in a simple shaft furnace with a simple row of nozzles be carried out and represents an extraordinarily great economic advance.
