KLASSE 40: Hüttenwesen.CLASS 40: Metallurgy.
Um kupferhaltige Laugen, wie solche bei bekannten Hüttenprocessen gewonnen werden, zu verwerthen, verfährt man so:To alkaline solutions containing copper, such as those at known metallurgical processes are obtained, to utilize, one proceeds as follows:
Die Lauge wird, falls das Kupfer als Sulfat enthalten ist, mit einer äquivalenten Menge Kochsalz oder eines anderen Chlorides, wie Chlorkalium, versetzt.If the copper is contained as sulphate, the lye is mixed with an equivalent amount Table salt or another chloride, such as potassium chloride, is added.
Cu SO4 + 2NaCl= Na2 SO4 + Cu Cl2. Cu SO 4 + 2NaCl = Na 2 SO 4 + Cu Cl 2 .
Enthält sie dagegen überschüssiges Kochsalz, so wird sie mit einer diesem überschüssigen Kochsalz entsprechenden Menge Kupfervitriol oder eines analogen Metallsulfats versetzt.If, on the other hand, it contains excess table salt, it becomes excess with one of these Table salt is added to the corresponding amount of vitriol or an analogous metal sulfate.
Hierdurch wird bewirkt, dafs in der Lösung Kupferchlorid neben Glaubersalz ist. Diese Kupferchloridlösung wird nunmehr in einem Rührwerk mit metallischem Kupfer behandelt.This has the effect that copper chloride is in the solution in addition to Glauber's salt. These Copper chloride solution is now treated with metallic copper in a stirrer.
Es entsteht durch die Einwirkung des metallischen Kupfers unlösliches Kupferchlorür, gleichzeitig wird etwa in der Lösung vorhandenes Silber metallisch niedergeschlagen.At the same time, insoluble copper chlorine is created by the action of the metallic copper any silver present in the solution is deposited in a metallic manner.
Cu Cl2 +Cu= Cu2 Cl2 2 Ag Cl2 + 2 Cu = Cm2 Cl2 + 2 Ag. Cu Cl 2 + Cu = Cu 2 Cl 2 2 Ag Cl 2 + 2 Cu = Cm 2 Cl 2 + 2 Ag.
Die zurückbleibende Mutterlauge enthält nur Spuren von Kupfer, geringe Mengen Eisen, Nickel u. s. w. und ist zur Gewinnung von Glaubersalz geeignet. Durch Oxyde, Carbonate, Sulfide u. s. w. können diese Verunreinigungen entfernt und dadurch die Gewinnung eines reinen Salzes gesichert werden.The remaining mother liquor contains only traces of copper, small amounts of iron, Nickel etc. and is suitable for the extraction of Glauber's salt. By oxides, carbonates, Sulphides and the like can remove these impurities and thereby the recovery of a pure salt.

2Na Cl.2Na Cl.
Enthalten die Laugen freie Säure, so wird solche am zweckmäfsigsten durch Kupferoxyd oder Kupferoxydul abgestumpft.If the alkalis contain free acid, it is most expedient to use copper oxide or copper oxide blunted.
Zur Fällung des Kupfers aus den Chloridlaugen kann statt Kupfer auch Kupferoxydul
oder Kupferoxydulcarbonat ganz oder theilweise verwendet werden. Hierdurch werden
auch Eisen, Mangan und sonstige in der Lauge vorhandene Metalle gefällt.
Cu Cl2 + Cu2 (O H)2 = Cu (O H)2 + Cu2 Cl2
Fe Cl2 + Cu2 (O H)2 = Fe (O H)2 + Cu2 Cl2. For the precipitation of copper from the chloride liquors, copper oxide or copper oxide carbonate can also be used in whole or in part instead of copper. This also precipitates iron, manganese and other metals present in the lye.
Cu Cl 2 + Cu 2 (OH) 2 = Cu (OH) 2 + Cu 2 Cl 2 Fe Cl 2 + Cu 2 (OH) 2 = Fe (OH) 2 + Cu 2 Cl 2 .
Das erforderliche Kupferoxydul wird am einfachsten dadurch erzeugt, dafs Kupferchlorür mit Aetzkalk behandelt wird.The easiest way to produce the necessary copper oxide is to use copper chloride is treated with caustic lime.
Die in beschriebener Weise erhaltenen Niederschläge, welche Silber, Kupfer, Kupferoxydul, Kupferchlorür, Kupferoxyd u. s. w. enthalten können, werden in geeigneter Weise derart in Form von Kupferchlorür gelöst, dafs diese Lösung frei wird von Silber, Wismuth, Arsen-Antimon. Dieselbe wird sodann an den Kathoden eines elektrolytischen Bades auf reines Kupfer verarbeitet.The precipitates obtained in the manner described, which contain silver, copper, copper oxide, Copper chloride, copper oxide and the like are suitably used in this way in Dissolved in the form of copper chloride, so that this solution becomes free of silver, bismuth, arsenic-antimony. It is then applied to pure copper on the cathodes of an electrolytic bath processed.
Auch können die erhaltenen Kupferniederschläge bezw. deren Lösungen mit Aetzkalk behandelt und das erhaltene Oxyd oder Oxydul auf trockenem Wege zu Gute gemacht werden. Cm2 Cl2 + Ca (OH)2 — Cu2 (OH)2 + Ca Cl2. The copper deposits obtained can also bezw. the solutions of which are treated with quicklime and the oxide or oxide obtained is made good by dry means. Cm 2 Cl 2 + Ca (OH) 2 - Cu 2 (OH) 2 + Ca Cl 2 .
Selbstverständlich können die betreffenden Niederschläge oder deren Lösungen auch durch Eisen oder andere Metalle reducirt werden.Of course, the precipitates in question or their solutions can also through Iron or other metals are reduced.

Bei diesem Verfahren der Entkupferung von Laugen die vollständige oder theilweise Ersetzung des als Fällungsmittel wirkenden metallischen Kupfers durch Kupferoxydul oder Kupferoxydulcarbonat.of table salt or other chlorides, e.g. B. potassium chloride, on the other hand, after an adverse effect of chloride (alkali chloride) was present, an equivalent amount of copper sulphate was added to the latter, the possibly present silver is precipitated metallic by metallic copper, the copper on the other hand is precipitated as chlorine, after which the remaining mother liquor, which can also be purified by oxides or sulphides and, in particular, made iron-free, so that the alkali sulphate contained therein can be processed.
In this process of copper removal from alkalis, the complete or partial replacement of the metallic copper, which acts as a precipitating agent, by copper oxide or copper oxide carbonate.
