Description

Verfahren zur Sinterröstung von schwefelhaltigen Zinkerzen Die Erfindung betrifft ein Verfahren zur Sinterröstung von schwefelhaltigen Zinkerzen auf einem Gebläseapparat unter Zuschlag von entschwefeltem Material.Process for the sinter roasting of sulphurous zinc ores The invention relates to a process for sinter roasting of sulfur-containing zinc ores on one Blower apparatus with the addition of desulphurized material.

Wenn ein solches Erz in feiner Verteilung und insbesondere als Flotationsendprodukt vorliegt, so ist zwar eine vollkommene und schnelle Entschwefelung ohne Schwierigkeit durchführbar; indessen hat die feine Verteilung bei der nachfolgenden Reduktion und Destillation in Retorten usw. Nachteile im Gefolge, so z. B. eine schlechte Wärmeübertragung und eine Schmelzung der Charge mit daran anschließender Bildung von Schlacke.If such an ore is finely divided and especially as a flotation end product is present, a complete and rapid desulfurization is without difficulty feasible; however, the fine distribution in the subsequent reduction and distillation in retorts etc. B. a bad one Heat transfer and melting of the batch with subsequent formation of slag.

Um nun ein Produkt zu erhalten, welches in befriedigender Weise vorgesintert ist, aber ohne die erwähnten Nachteile reduziert und destilliert werden kann, ist vorgeschlagen worden, den Prozentgehalt an Schwefel zunächst durch einen gewöhnlichen Röstprozeß in einem Muffel- oder Flammofen zu verringern und dann das teilweise abgeröstete Produkttot zu rösten.In order to obtain a product which has been pre-sintered in a satisfactory manner is, but can be reduced and distilled without the disadvantages mentioned It has been proposed to initially change the percentage of sulfur by an ordinary To reduce the roasting process in a muffle or flame furnace and then partially roasting roasted product dead.

Die Notwendigkeit zweier Apparaturen mit den damit verbundenen Unzuträglichkeiten erhöht die Kosten des Prozesses dergestalt, daß der Betrieb unökonomisch wird.The necessity of two apparatuses with the associated inconveniences increases the cost of the process so that it becomes uneconomical to operate.

Es ist auch bekannt, schwefelhaltigen Ausgangsstoffen ein Material zuzumischen, das Rückfälle aus einem Sinterverfahren darstellt. Demgegenüber benutzt die vorliegende Erfindung als Zuschlag zu dem Feinerz ein vollkommen gesintertes und zerkleinertes Zinkagglomerat in solcher Menge, daß eine Mischung von 6 bis 1511/o Schwefel entsteht. Das Agglomerat kann durch Sinterung von oxydischen, kohlensauren oder sulfidischen Zinkmaterialien hergestellt sein.It is also known to source a material containing sulfur to be admixed, which represents relapses from a sintering process. Used in contrast the present invention as an addition to the fine ore a completely sintered one and crushed zinc agglomerate in such an amount that a mixture of 6 to 1511 / o Sulfur is produced. The agglomerate can be produced by sintering oxidic, carbonic acid or sulfidic zinc materials.
