KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Entfernung des Mangans und Eisens aus Zinklaugen, welche später entweder auf Zink oder auf Zinkverbindungen, ζ. Β. auf Lithopone verarbeitet werden sollen, erfolgt bekanntlich, indem man die Laugen mit Zinkoxyd oder Hydroxyd, basischem Zinksalz oder Calciumkarbonat in Gegenwart eines Oxydationsmittels behandelt. Als' letzteres wurde bisher im allgemeinen Chlorkalk verwendet, während beim Durchblasen von Luft zwar die Entfernung des Eisens, nicht aber die des Mangans gelang.The removal of the manganese and iron from zinc lye, which later on either Zinc or on zinc compounds, ζ. Β. to be processed on Lithopone takes place as is well known, by treating the lyes with zinc oxide or hydroxide, basic zinc salt or treated calcium carbonate in the presence of an oxidizing agent. As' the latter has heretofore been generally used chlorinated lime while blowing air the iron was removed, but the manganese was not.
Es wurde nun gefunden, daß sich zur Fällung beider Metalle sehr gut Bleisuperoxyd eignet, und zwar geht die Reinigung glatt vor sich, wenn man die neutrale Zinklösung mit etwas Bleisuperoxyd behandelt. Fördernd wirkt hierbei noch die Gegenwart von etwas Zinkoxyd oder von durch Alkalien.It has now been found that lead peroxide can be used very well for the precipitation of both metals suitable, and the cleaning goes smoothly if you use the neutral zinc solution treated with some lead peroxide. The presence of some zinc oxide or alkalis has a beneficial effect here.
oder alkalische Erden ausgefälltem Zinkoxydhydrat. Ein Überschuß des Bleisuperoxydes ist hierbei infolge seiner praktischen Unlöslichkeit in der Lauge unschädlich. Da auch die aus dem Superoxyd durch Reduktion entstehenden Bleiverbindungen praktisch unlöslich sind, ist es nicht erforderlich, die Bleiverbindungen erst wieder aus der Lauge zu entfernen. Aus demselben Grunde ist eine Verunreinigung des Bleisuperoxydes durch Bleisulfat für den Prozeß belanglos, und es läßt sich daher sehr gut der in Bleiakkumulatoren entstehende Bodensatz verwenden , der aus Bleisuperoxyd nebst Bleisulfat besteht, selbstverständlich nachdem er durch Waschen oder Neutralisieren von freier Schwefelsäure befreit ist. Da dieser Bodensatz leicht in großen Mengen als Abfallprodukt zu haben ist und auch nach seiner Verwendung zur Reinigung der Zinklaugen seinen vollen Metallwert behält, sind die Kosten dieser Reinigung sehr gering.or alkaline earths precipitated zinc oxide hydrate. An excess of lead peroxide is harmless here due to its practical insolubility in the lye. There also the lead compounds formed from the superoxide by reduction are practical are insoluble, it is not necessary to first remove the lead compounds from the lye to remove. For the same reason, contamination of the lead peroxide by lead sulphate is irrelevant for the process, and the sediment that arises in lead accumulators can therefore be used very well , which consists of lead peroxide together with lead sulphate, of course after washing or neutralizing free Sulfuric acid is freed. Because this sediment easily becomes a waste product in large quantities is available and retains its full metal value even after it has been used to clean the zinc lye The cost of this cleaning is very low.
Die Verwendung derartiger Gemische aus Bleisuperoxyd und -Sulfat bietet gegenüber dem reinen Superoxyd noch den Vorteil, daß die Reinigung der Zinklaugen schneller erfolgt, da sich die Niederschläge rascher zu Boden setzen. Es erklärt sich dies in einfacher Weise dadurch, daß für eine bestimmte Oxydationswirkung, also auch für die Fällung einer bestimmten Menge Eisen und Mangan ein größeres Gewicht von Bleisuperoxyd und -Sulfatgemisch nötig ist als von reinem Superoxyd. Infolgedessen enthält, auf dieselbe Menge Mangan und Eisenverbindungen berechnet, der erstere Niederschlag mehr Blei als der letztere, hat daher ein höheres spezifisches Gewicht.The use of such mixtures of lead peroxide and sulfate offers opposite the pure superoxide also has the advantage that the cleaning of the zinc lye is quicker, as the precipitation settles on the ground more quickly. There is a simpler explanation for this Way in that for a certain oxidizing effect, thus also for the precipitation of a certain amount of iron and manganese a greater weight of lead peroxide and sulphate mixture is necessary than of pure superoxide. As a result, it contains the same amount of manganese and iron compounds calculated, the former precipitate has more lead than the latter, and therefore has a higher specific gravity.
Ein Beispiel für den Prozeß ist folgendes: Zinksulfat, welches etwa 1,1 Prozent Mangan enthält, wird durch Behandeln der wässerigen Lösung mit 16 Prozent neutralem Bleischlamm, der 33 Prozent Bleisuperoxyd enthält, bei Zimmertemperatur in einer halben Stunde, in der Wärme in noch kürzerer Zeit,An example of the process is the following: zinc sulfate, which is about 1.1 percent manganese is made by treating the aqueous solution with 16 percent neutral Lead sludge, which contains 33 percent lead peroxide, at room temperature in half Hour, in the warmth in even less time,
vollkommen frei von Mangan. Ebenso wie Mangan wird auch Eisen vollständig · aus Zinksulfatlauge entfernt.completely free of manganese. Like manganese, iron is also completely eliminated Zinc sulphate liquor removed.
