Gegenstand der Erfindung ist ein Verfahren zur Trennung der Bestandteile gemischter, insbesondere bleihaltiger, sulfidischer Zinkerze auf nassem Wege und zur Gewinnung der einzelnen Bestandteile, derart, daß der ganze Prozeß unter Verwertung sämtlicher Nebenprodukte einen geschlossenen Kreislauf darstellt.The invention relates to a method for separating the components of mixed, in particular lead-containing, sulphidic zinc ores on the wet route and for extraction of the individual components, in such a way that the whole process utilizes all of them By-products represents a closed cycle.
Bei den bisher bekannten Verfahren zur ίο Verarbeitung gemischter sulfidischer Zinkerze auf nassem Wege war es nötig, die Erze zunächst zu rösten, worauf dieselben mit verdünnter Ferrisulfatlösung behandelt wurdenIn the previously known processes for processing mixed sulphidic zinc ores on the wet road it was necessary to first roast the ores, after which they were diluted with Ferric sulfate solution were treated
(D. R. P. 78159)·(D. R. P. 78159)
Vorliegendes Verfahren ermöglicht es hingegen, unmittelbar von Roherzen auszugehen, wodurch eine Verbesserung des Verfahrens und eine zweckmäßigere Gewinnung der einzelnen Bestandteile erzielt wird.The present method, however, makes it possible to start directly from raw ore, whereby an improvement of the process and a more expedient recovery of the individual Components is achieved.
Die Ausführung des Verfahrens gestaltet sich wie folgt:The procedure is carried out as follows:
Zunächst wird das Roherz pulverisiert, und zwar nicht nur fein im gewöhnlichen Sinne, sondern bis zu einem unfühlbaren Pulver gemahlen und hierauf bei Siedehitze oder unter Druck mit einer konzentrierten Lösung von Ferrisulfat, dessen Lösefähigkeit für Zinksulfid an sich bekannt ist, behandelt. Diese Lösung hat zweckmäßig einen Gehalt von IOO g Eisen und IOO g freier Schwefelsäure pro Liter. Durch das Ferrisulfat werden die Sulfide nach der bekannten Reaktion:First, the raw ore is pulverized, and not just fine in the ordinary Senses, but ground to an impalpable powder and then at the boiling point or under pressure with a concentrated solution of ferric sulphate, its solubility for zinc sulfide is known per se. This solution expediently has a content of 100 g iron and 100 g free sulfuric acid per liter. Be by the ferric sulfate the sulphides according to the well-known reaction:
ZnS + Fe2 (S OJS
= Zn S O4 + 2 Fe S O4 + 5 ZnS + Fe 2 (S OJ S
= Zn S O 4 + 2 Fe S O 4 + 5
in Sulfate unter Abscheidung freien Schwefels verwandelt, welcher auf diese Weise in bequemer und wirtschaftlich vorteilhafter Form gewonnen werden kann. Die Reaktion verläuft quantitativ nur, wenn das Roherz außerordentlich fein pulverisiert war. In diesem 'Falle geht alles Zink als Sulfat in Lösung, welche durch Filtrieren von den unlöslichen bleihaltigen Rückständen getrennt wird. Das aus einem Gemisch von Ferrosulfat und Zinksulfat bestehende Filtrat wird nun, um die Ausscheidung eines Doppelsalzes von Zink und Eisen zu vermeiden, in heißem Zustand der Oxydation unterworfen, welche in Anbetracht der konzentrierten Ferrosulfatlösung zweckmäßig mit Salpetersäure unter Regeneration der nitrosen Dämpfe in üblicher Weise erfolgt. Nach erfolgtet Oxydierung des Eisens wird' die Lösung abgekühlt, wobei bei genügendem Zinkgehalt dieses als. Sulfat auskristallisiert, während das Eisen als leicht lösliches Ferrisulfat in der Mutterlauge zurückbleibt. Das Zinksulfat wird von dieser getrennt und nach dem Trocknen in einem Muffelofen zur Über-converted into sulphates with deposition of free sulfur, which in this way is more convenient and economically advantageous form can be obtained. The reaction proceeds quantitatively only if the raw ore was extremely finely pulverized. In this case all zinc goes in as sulphate Solution, which is separated from the insoluble lead-containing residues by filtration will. The filtrate, which consists of a mixture of ferrous sulfate and zinc sulfate, is now, in order to avoid the excretion of a double salt of zinc and iron subject to oxidation in the hot state, which given the concentrated Ferrous sulphate solution is advisable with nitric acid with regeneration of the nitrous vapors takes place in the usual way. After the iron has been oxidized, the solution is cooled with sufficient zinc content this as. Sulphate crystallizes out, while the iron as easily soluble ferric sulphate in the mother liquor remains. The zinc sulphate is separated from this and after drying in a muffle furnace for over-
führung in Zinkoxyd in bekannter Weise kalziniert, wobei die entweichenden sauren Gase zur Gewinnung der Eisenlösung Verwendung finden.Lead in zinc oxide calcined in a known manner, with the escaping acids Find gases to obtain the iron solution use.
Das so erhaltene Zinkoxyd ist frei von Blei und anderen Metallen und ergibt nach der Reduktion mit Kohle reines Zink.The zinc oxide thus obtained is free from lead and other metals and yields the reduction with coal is pure zinc.
Der bei der Filtration erhaltene unlösliche Rückstand enthält das Blei, die Gangart undThe insoluble residue obtained in the filtration contains the lead, gangue and
ίο den gebildeten Schwefel. Letzterer wird durch Destillation gewonnen und der Bleirückstand nach bekannten Methoden zu Blei verarbeitet. Das gesamte Verfahren erfordert daher zur Gewinnung sämtlicher in dem Erz enthaltenen Bestandteile nur rohes, ungeröstetes Erz als Ausgangsstoff sowie Kohle und eine kleine Menge Natriumnitrat zur Oxydation der Eisenlösung.ίο the sulfur formed. The latter will obtained by distillation and the lead residue converted to lead by known methods processed. The entire process therefore requires recovering all of the ore Contains only raw, unroasted ore as a starting material and coal and a small amount of sodium nitrate to oxidize the iron solution.
Enthält das sulfidische Zinkerz noch andere Metalle, wie z. B. Kupfer, Silber, Gold, Eisen und Mangan, so wird die Behandlung dementsprechend abgeändert. Kupfer, Gold und Silber bleiben zum großen Teil mit dem unlöslichen Bleirückstand zurück, wobei das Kupfer auf der Bleiverhüttung als Kupferstein gewonnen wird und die Edelmetalle sich mit dem Blei legieren.Does the sulfidic zinc ore contain other metals, such as B. copper, silver, gold, iron and manganese, the treatment is modified accordingly. Copper, gold and silver for the most part remain with the insoluble Lead residue back, whereby the copper is extracted from the lead smelting as copper stone and the precious metals alloy with the lead.
Mangan und ein Teil des Eisens werden bei der Behandlung des Erzes mit Ferrisulfat in lösliche Sulfate übergeführt; da die Lösung immer reicher an Eisen wird, muß dessen Gehalt von Zeit zu Zeit entsprechend reduziert werden. Dies kann beispielsweise durch Niederschlagen des überschüssigen Eisens mit selbsterzeugtem Zinkoxyd erfolgen, welches als Eisenhydrat oder basisches unlösliches Ferrisulfat abfiltriert, während die Zinklösung zu dem Verfahren zurückgeführt wird.Manganese and some of the iron are used in the treatment of the ore with ferric sulfate converted into soluble sulfates; as the solution becomes richer and richer in iron, its content must correspond from time to time be reduced. This can be done, for example, by knocking down the excess Iron made with self-produced zinc oxide, which as iron hydrate or basic insoluble ferric sulfate is filtered off while the zinc solution is returned to the process will.
Mangan löst sich als Mangansulfat so lange auf,, bis eine heißgesättigte Lösung entsteht. Da Mangansulfat jedoch in der Kälte leichter löslich ist als in der Wärme, so kristallisiert mit dem Zinksulfat kein Mangansulfat aus. Sobald jedoch die Lösung mit Mangan gesättigt ist, bleibt der Rest des Mangans zusammen . mit'!dem Bleirückstand. Diesen Mangangehalt; kann man aus dem unlöslichen Rückstand nach erfolgter Befreiung von anhaftender Mutterlauge durch Waschen mit Mangansulfatlösung und durch Auslaugen des gewaschenen Rückstandes mit reinem Wasser gewinnen, um es entweder auszukristallisieren oder durch Kalzination des Mangansulfats Manganoxyd darzustellen.Manganese dissolves as manganese sulphate until a hot, saturated solution is formed. However, since manganese sulphate is more soluble in the cold than in the warm, no manganese sulphate crystallizes out with the zinc sulphate. However, once the solution is saturated with manganese, the rest of the manganese stays together. with ' ! the lead residue. This manganese content ; can be obtained from the insoluble residue after it has been freed from adhering mother liquor by washing with manganese sulfate solution and by leaching the washed residue with pure water in order to either crystallize it out or to produce manganese oxide by calcination of the manganese sulfate.
