Description

Darstellung von Kupferchlorür. In den deutschen Patentschriften 384224 und 395434 sind Verfahren zur Darstellung von Kupferchlorür in neutraler bzw. alkalischer Lösung beschrieben.Representation of copper chloride. In German patents 384224 and 395434 are methods for the preparation of copper chloride in neutral and alkaline, respectively Solution described.

Es wurde nun gefunden, daß man zur Darstellung derartiger Lösungen gemäß Patent 384224 statt des Kupfermetalls auch Kupfererze., z. B. Kupferoxyd, Schwefelkupfer, Kupferoxydul und ähnliche Verbindungen vorteilhaft verwenden kann. Die Verarbeitung derartiger Verbindungen läßt sich namentlich bei Vorhandensein gewisser Verunreinigungen in neutraler bzw. alkalischer Lösung unter ganz besonders günstigen Bedingungen ausführen. Da nämlich ohne jeden Gehalt an freier Säure gearbeitet wird, bleiben beim Auflösen des Kupfererzes die säurelöslichen Verunreinigungen des Kupfererzes ungelöst zurück. Man kann schon an der milchigen Trübung der Löseflüssigkeit leicht erkennen, daß kein Cberschuß von Säurevorhanden ist, und daß stets in neutraler bzw. alkalischer Lösung gearbeitet wird.It has now been found that to represent such solutions according to patent 384224 instead of copper metal also copper ores., z. B. copper oxide, Copper sulphide, copper oxide and similar compounds can advantageously use. The processing of such connections can be carried out in particular if they are present certain impurities in neutral or alkaline solution under very special run under favorable conditions. Because it worked without any free acid content the acid-soluble impurities remain when the copper ore is dissolved of the copper ore back undissolved. One can already see the milky cloudiness of the dissolving liquid easily see that there is no excess acid and that it is always neutral or alkaline solution is used.

Handelt es sich z. B. um die Auflösung von Kupfersulfür, dann arbeitet man zweckmäßig in einem Rühr«-erkbottich, in dem das zu lösende fein gemahlene Kupfersulfür aufgeschlemmt wird. Die Auflösung des Kupfersulfürs geht gleich rasch und einwandfrei vonstatten und erfolgt unter Schwefelabscheidung.Is it z. B. to the dissolution of copper sulphur, then works it is expedient to put the finely ground copper sulphate in a stirred kettle is swallowed up. The dissolution of the copper sulphate is quick and easy take place and takes place with sulfur separation.

Bei sehr hoch konzentriertem Kupfersulfür kann man selbstverständlich auch finit gröber zerkleinertem Erz arbeiten, doch ist hier eine intensive Abspülung durch geeignete Bewegung iin Rührwerk oder in einem Zirkulationsgefäß nötig, um die sich auf der Oberfläche der Erzkörner bildenden Schwefelpartikelchen von dem noch unveränderten Erz zu entfernen und so ein weiteres Angreifen der Lösungsflüssigkeit zu erleichtern. Ausführungsbeispiel. In einem Liter Wasser wurden gelöst t 5o g Kochsalz. Hierauf wurden in fein verteiltem Zustande 8o g Kupfersulfür zugesetzt und tropfenweise Salzsäure unter leichtem Erwärmen der Lösung und intensivem Umrühren Luft eingeleitet. Nach ungefähr zweistündigem Einleiten «-ar in dem verbleibenden Rückstand, der aus Schwefel bestand, nur noch ¢ g Kupfer enthalten. Das Kupfer war mithin zu annähernd 95 Prozent aufgelöst.With very highly concentrated copper sulphide you can of course also work finitely coarsely crushed ore, but this requires intensive rinsing necessary by suitable agitation in a stirrer or in a circulation vessel the sulfur particles formed on the surface of the ore grains from the to remove unchanged ore and so further attack the solution liquid to facilitate. Embodiment. 50 g were dissolved in one liter of water Table salt. Then 80 g of copper sulphide were added in a finely divided state and dropwise hydrochloric acid while gently warming the solution and stirring vigorously Air introduced. After about two hours of introducing «-ar in the remaining one Residue, which consisted of sulfur, only contained ¢ g of copper. The copper was therefore almost 95 percent dissolved.
