Description
Es ist bekannt, daß man Zink aus den Rückständen gerösteter Pyrite durch Behandlung mit Chlor in statu nascendi in saurer Flüssigkeit bei einer Temperatur von ungefähr 70 bis 8o° extrahieren kann.It is known that zinc can be obtained from the residues of roasted pyrite by treatment with chlorine in statu nascendi in acidic liquid at a temperature of about Can extract 70 to 8o °.
Es wurde nun gefunden, daß sich der Zink aus den Kiesabbränden auch dadurch entfernen läßt, daß man sie mit Salzsäure oder Kochsalz und verdünnter Schwefelsäure, zweckmäßig in berechneten Mengen, unter gleichzeitiger Einwirkung von Chlor auslaugt. Man erhält auf diese Weise eine Entzinkung von Kiesabbränden bis zu 0,3 Prozent Zn. Die so erhaltenen Zink&ulfatlaugen können z. B. mit Hilfe von Chlorkalzium in Chlorid übergeführt und mittels Ca O als Zinkoxyd gefällt werden. Wird statt Kochsalz und Schwefelsäure nur Salzsäure verwendet, so kann das Zink direkt alz Oxyd gefällt werden.It has now been found that this also removes the zinc from the gravel burns lets them with hydrochloric acid or common salt and dilute sulfuric acid, expedient leaches in calculated amounts, with simultaneous exposure to chlorine. You get in this way a dezincification of gravel burns up to 0.3 percent Zn Zinc & sulphate lye can e.g. B. converted into chloride with the help of calcium chloride and be precipitated as zinc oxide by means of Ca O. Used instead of table salt and sulfuric acid only If hydrochloric acid is used, the zinc can be precipitated directly as oxide.
Bei dem vorhegenden Verfahren wird nicht, wie bei dem obenerwähnten bekannten, das Chlor in statu nascendi gebraucht und daher die Verwendung des kostspieligen Hypochlorits gespart. Hierdurch wird ein großer technischer Fortschritt erzielt, da ein solches Verfahren erst Anspruch auf praktische Verwendbarkeit erheben kann.In the present method is not, as in the above-mentioned known, the Chlorine used in statu nascendi and therefore the use of the expensive hypochlorite saved up. This makes great technical progress, as such a process can only lay claim to practical usability.
