Description
Verfahren zur Darstellung von Kupferchlorürlösung. Im Patente; K1. un, ist ein Verfahren zur Auflösung von Kupfer und Kupferlegierungen unter Zuhilfenahme von Kupferchlorid, Kupferchlorür bzw. basischen Kupferchloriden oder Kupferoxydulchloriden und unter Zusatz von geringen Säuremengen beschrieben. Es wurde nun gefunden, daß an Stelle von Salzsäure und Luft mit besonderem Vorteil Chlor verwendet werden kann. Der durch= die Verwendung von Chlor erreichte Vorteil besteht hauptsächlich darin, daß durch die größere Wärmeentwicklung eine erhebliche Beschleunigung des Lösungsvorganges eintritt.Process for the preparation of copper chloride solution. Im patents; K1. well, is a method for dissolving copper and copper alloys with the aid of copper chloride, copper chloride or basic copper chlorides or copper oxychloride and described with the addition of small amounts of acid. It has now been found that Instead of hydrochloric acid and air, chlorine can be used with particular advantage. The advantage achieved by = the use of chlorine is mainly: that a considerable acceleration of the dissolution process due to the greater heat development entry.
Der bisher unbekannte und nicht vorauszusehende Erfolg aber besteht darin, daß man beim Arbeiten in neutraler oder schwach alkalischer Lösung bei Anwesenheit von genügend Kochsalz und Kupfermetall bzw. Kupferlegierung oder reduktionsfähigem Kupfererz nicht etwa Kupferchlorid, sondern im wesentlichen in der Lösung Kupferchlorür erhält. Die Geschwindigkeit der Auflösung ist hierbei annähernd die gleiche wie bei Auflösung von geglühtem Kupferoxyd in Säure. Beispiel.The previously unknown and unforeseeable success, however, persists that when working in a neutral or weakly alkaline solution in the presence of sufficient table salt and copper metal or copper alloy or reducible Copper ore not, for example, copper chloride, but essentially in the solution copper chloride receives. The speed of dissolution here is approximately the same as when annealed copper oxide is dissolved in acid. Example.
Zoo 1 Kochsalzlösung vom spezifischen Gewicht 1,15 werden mit etwa Zoo g Kupferchlorid versetzt und mit dem zu lösenden Material (Kupfer, Kupferlegierungen, Kupfererze oder kupferhaltige Rückstände) je nach Form in einem Rührwerksbottich oder in einem mit Siebboden versehenen Behälter behandelt, in dem man Chlor einleitet. Durch Zusatz von etwas Kupferoxyd wird eine eventuelle saure Reaktion beseitigt. Der Chlorstrom wird geregelt, daß man nur eine Lösung von Kupferchlorür erhält.Zoo 1 saline solution with a specific gravity of 1.15 will be approx Zoo g copper chloride is added and the material to be dissolved (copper, copper alloys, Copper ores or residues containing copper) in an agitator vat, depending on the shape or treated in a container provided with a sieve bottom, into which chlorine is introduced. Any acidic reaction can be eliminated by adding a little copper oxide. The flow of chlorine is regulated so that only a solution of copper chloride is obtained.
Das Verfahren läßt sich gleichgut auf Kupfer, kupferhaltige Rückstände, Kupfererze und Kupferlegierungen anwenden. Statt Kochsalz können andere Alkali- oder Erdalkalichloride Verwendung finden.The process can be applied equally well to copper, copper-containing residues, Use copper ores and copper alloys. Instead of table salt, other alkali or alkaline earth chlorides are used.
