KAISERLICHESIMPERIAL
PATENTAMT. WPATENT OFFICE. W.
Bei den Blenderöstöfen der Zinkhütten fällt eine nicht unbedeutende Menge Flugstaub ab, welcher reichlich Zinkvitriol und schwefelsaures Eiseiioxydul enthält und bislang fast gar nicht nutzbar gemacht wurde. Das von mir gefundene Verfahren zur Nutzbarmachung dieses Flugstaubes besteht im wesentlichen darin, dafs ich dem Flugstaub das in ihm in Form von Sulfat vorhandene Zink (10 bis 13 pCt., oft auch bis 21 pCt.) und Eisen (2 bis 3 pCt., mitunter bis 24 pCt.) durch Wasser entziehe und diese Metalle entweder direct oder indirect mit Soda oder einem anderen geeigneten Carbonat ausfälle, wodurch ich einen künstlichen Galmei mit 45 bis 50 pCt. Zink erhalte, der wieder in die Zinkfabrikation geht. Die Ausführung meines Verfahrens erfolgt in etwas verschiedener Weise, je nachdem ich verschiedene Nebenproducte gewinnen will.A not insignificant amount of flue dust falls off the blender roasting ovens of the zinc works, which contains plenty of zinc vitriol and sulfuric acid iron oxide and so far hardly at all was made usable. The method I found to utilize this Airborne dust consists essentially in the fact that the airborne dust has that in it in the form of Zinc present in sulphate (10 to 13 pCt., Often also up to 21 pCt.) and iron (2 to 3 pCt., sometimes up to 24 pCt.) with water and these metals either directly or indirectly with soda or some other suitable carbonate failures, whereby I have an artificial calamine with 45 to 50 pCt. Get zinc that goes back to zinc production. The execution of my procedure takes place in something in different ways, depending on how I want to get different by-products.
Circa 1000 kg Flugstaub werden mit Wasser ausgelaugt, worauf man die Lösung, am besten heifs, mit calcinirter Soda versetzt, bis Zink und Eisen völlig als Carbonat gefällt sind. Da sich für die Ausfällung ein geringer Ueberschufs an Soda vortheilhaft erweist, so giebt man so viel Soda zu, bis die Flüssigkeit sehr deutlich alkalisch reagirt. Nachdem Klärung erfolgt ist, zieht man die Lösung von dem ausgeschiedenen Gemenge von Zink- und Eisencarbonat ab, wäscht letzteres nochmals mit Wasser und trocknet sodann bei gewöhnlicher Temperatur. Der so gewonnene künstliche Galmei enthält 45 bis 50 pCt. Zink und ist zur Verhüttung auf Zink sehr geeignet.Approximately 1000 kg of airborne dust are leached out with water, whereupon the solution is best hot, mixed with soda ash, until zinc and iron are completely precipitated as carbonate. There A slight excess of soda proves beneficial for the precipitation, so gives so much soda is added that the liquid is very clearly alkaline. After clarification is done, the solution is removed from the precipitated mixture of zinc and iron carbonate, the latter is washed again with water and then dry at ordinary temperature. The artificial one obtained in this way Calamine contains 45 to 50 pCt. Zinc and is very suitable for smelting on zinc.
Das Filtrat, welches neben Glaubersalz noch wenig Soda enthält, wird mit Schwefelsäure neutralisirt und zur Krystallisation des Sulfats eingedampft.The filtrate, which contains little soda in addition to Glauber's salt, is treated with sulfuric acid neutralized and evaporated to crystallize the sulfate.
An Stelle der Soda kann auch Kalium- oder Ammoniumcarbonat zur Ausfällung des Zinks und Eisens dienen, in welchem Falle Kaliumoder Ammonsulfat als Nebenproduct resultiren.Potassium or ammonium carbonate can also be used in place of soda to precipitate the zinc and iron, in which case potassium or ammonium sulphate result as a by-product.
Ich erhielt aus 1000 kg Flugstaub, der 11 pCt. Zink und 2 pCt. Eisen enthielt, 200 bis 250 kg Galmei (mit 45 bis 50 pCt. Zink) im Werth von 29 bis 32 Mark und ca. 260 kg wasserfreies oder 590 bis 600 kg krystallisirtes Glaubersalz. Da der Sodaverbrauch 190 bis 200 kg betrug, so werden die Kosten hierfür bereits durch das gewonnene Natriumsulfat gedeckt. Der beim Auslaugen des Flugstaubes mit Wasser hinterbleibende Rückstand ist sehr eisenreich und könnte event, als Hochofenmaterial verwendet werden.I received from 1000 kg of fly ash, the 11 pct. Zinc and 2 pCt. Iron contained 200 to 250 kg calamine (with 45 to 50 pCt. Zinc) in the Worth from 29 to 32 marks and about 260 kg of anhydrous or 590 to 600 kg of crystallized Glauber's salt. Since the consumption of soda was 190 to 200 kg, the cost thereof becomes already covered by the obtained sodium sulfate. The one when leaching the fly ash The residue left behind with water is very rich in iron and could possibly be used as blast furnace material be used.
Statt die durch Auslaugen des Flugstaubes erhaltene Lösung direct mit Soda zu fällen, kann man auch die völlig klare Lösung mit der zum Ausfällen der Schwefelsäure berechneten Menge einer Lösung von Bariumnitrat versetzen, wobei Bariumsulfat ausfällt, das, wenn die Lösung ganz klar war, also keine zu fällenden Eisentheilchen enthielt, nach dem Waschen und Trocknen rein weifs ist und als Blanc fixe abgegeben wird. Sind in dem schwefelsauren Barium nach mehrmaligem Waschen mit Wasser noch Spuren von Eisen vorhanden, so wäscht man mit verdünnter Salzsäure und neutralisirt schliefslich durch wenig Ammoniak. Das Filtrat mit dem Zink- und Eisennitrat behandle ich nun am besten heifs mit der zur Fällung erforderlichen Menge Soda (oder Kalium- oder Ammoncarbonat),Instead of precipitating the solution obtained by leaching the fly ash directly with soda, the completely clear solution can also be mixed with the amount of a solution of barium nitrate calculated for the precipitation of sulfuric acid, with barium sulfate precipitating, which, if the solution was completely clear, therefore none contains iron particles to be precipitated, is pure white after washing and drying and is given off as blanc fixe . If traces of iron are still present in the sulphate of barium after washing it several times with water, it is washed with dilute hydrochloric acid and finally neutralized with a little ammonia. The filtrate with the zinc and iron nitrate is best treated hot with the amount of soda (or potassium or ammonium carbonate) required for precipitation,
wodurch künstlicher Galmei gefällt wird, der gewaschen und getrocknet wird, während Natriumnitrat in Lösung bleibt, das man durch Eindampfen abscheidet.thereby precipitating artificial calamine which is washed and dried while Sodium nitrate remains in solution, which is separated off by evaporation.
Aus ι ooo kg Flugstaub mit 11 pCt. Zink und 2 pCt. Eisen in Form von Sulfat erhielt ich 200 bis 250 pCt. Galmei, ca. 475 kg Bariumsulfat und ca. 350 kg Chilisalpeter, während der Aufwand an Bariumnitrat ca. 530 kg und an Soda ca. 200 kg betrug.From ι ooo kg of fly ash with 11 pCt. zinc and 2 pCt. I received 200 to 250 pCt of iron in the form of sulphate. Calamine, approx. 475 kg Barium sulfate and approx. 350 kg of chilli nitrate, while the amount of barium nitrate is approx. 530 kg and about 200 kg of soda.
Durch mein vorbesprochenes, technisch leicht ausführbares neues Verfahren, welches auf einer Combination von im Einzelnen bekannten Reactionen beruht, wird, wie vorstehend ersichtlich, der bislang als fast werthloses Abfallsproduct betrachtete Flugstaub der BlenderöstThrough my previously discussed, technically easy to execute new process, which is based on a Combination of individually known reactions is based, as can be seen above, the fly dust of the blender roast, which was previously regarded as an almost worthless waste product
