In der metallurgischen Literatur findet sich hinsichtlich der Sulfate des Eisens, Nickels und Kupfers eine Anschauung vertreten, welche nach den Ergebnissen von den Erfindem vorgenommener Versuche nicht als allgemein gültig aufrechtzuerhalten ist.With regard to the sulphates of iron, nickel is found in the metallurgical literature and Kupfers hold a view which according to the results of the inventors attempts made cannot be maintained as generally valid.
Diese Anschauung faßt Schnabel in seiner Metallhüttenkunde (II. Aufl., Bd. II, S. 653) in die Worte: Ein Gemenge von Sulfaten des Eisens, Kupfers und Nickels kann so erhitzt werden, daß die Sulfate von Eisen und Kupfer in Oxyde und Schwefelsäure bzw. schweflige Säure und Sauerstoff zerfallen, während das Nickelsulfat zum größten Teile unzersetzt bleibt. Aus "dem Gemenge von Oxyden und Nickelsulfat kann das letztere durch Auslaugen mit Wasser bzw. (das basische Sulfat) mit verdünnten Säuren gewonnen werden.Schnabel grasps this view in his own Metallhüttenkunde (2nd ed., Vol. II, p. 653) in the words: A mixture of sulfates of iron, copper and nickel can be heated so that the sulphates of iron and Copper disintegrates into oxides and sulfuric acid or sulfurous acid and oxygen, while the nickel sulfate remains largely undecomposed. From "the mixture of Oxides and nickel sulphate can be obtained by leaching with water or (the basic sulphate) with diluted acids will.
Hiernach müßte man das sulfatisierende Rösten eisen- und kupferhaltiger Nickelerze so führen können, daß von den entstehenden Sulfaten zuerst das des Eisens, dann das des Kupfers wieder zersetzt würde und das des Nickels übrigbliebe, welch letzteres dann ausgelaugt werden könnte.According to this, one would have to roast iron- and copper-containing nickel ores by means of sulphating so that of the sulphates formed, first that of iron, then that of Copper would decompose again and that of nickel would remain, which is the latter could be leached out.
Diesbezügliche Versuche der Erfinder haben ergeben, daß das sulfatisierende Rösten eisen- und kupferhaltiger Nickelerze so geführt werden kann, daß in Wasser lösliches Kupfersulfat entsteht, welches sich unter Zurücklassung von Eisen und Nickel auslaugen läßt. Attempts by the inventors in this regard have shown that the sulphating roasting iron and copper-containing nickel ores can be conducted so that water-soluble copper sulfate arises, which can be leached leaving behind iron and nickel.
Auch eine andere in der amerikanischen Patentschrift Nr. 805555 von Hybinette angenommene Möglichkeit der Verarbeitung von Kupfernickelerzen hat sich als- praktisch schwer durchführbar erwiesen. Auch erscheint sie den Erfindern nicht als eine Vereinfachung bekannter Kupfernickelscheideprozesse. Hybinette will das Kupfer dadurch von dem Nickel trennen, daß er das Erz zuerst auf einen Konzentrationsstein von 25 Prozent Schwefel, 0,5 bis 5 Prozent Eisen, 35 bis 40 Prozent Kupfer und 40 bis 35 Prozent Nickel anreichert, diesen bis zur Überführung der Metalle in Oxyde abröstet und von den entstandenen Oxyden das Kupferoxyd mit Schwefelsäure auslaugt. Praktisch wird, wie schon aus der Patentbeschreibung hervorgeht, das Kupfer zunächst nicht vollständig gelöst, während andererseits neben dem gelösten Kupfer schon beträchtliche ' Mengen Nickel mit in die Lösung treten. Another possibility of processing copper-nickel ores, which was assumed by Hybinette in the American patent specification No. 805555, has also proven to be difficult to carry out in practice. Nor does it appear to the inventors to be a simplification of known cupronickel separation processes. Hybinette wants to separate the copper from the nickel by first concentrating the ore on a concentration stone of 25 percent sulfur, 0.5 to 5 percent iron, 35 to 40 percent copper and 40 to 35 percent nickel, until the metals are converted roasted in oxides and from the oxides formed leaches the copper oxide with sulfuric acid. In practice, as can already be seen from the patent description, the copper is not completely dissolved at first, while on the other hand, in addition to the dissolved copper, considerable amounts of nickel also enter the solution.
Im Gegensatz zu diesem Verfahren haben die Erfinder gefunden, daß man ohne Anreicherung des Erzes zu einem Konzentrationsstein so rösten kann, daß die Hauptmenge des Kupfers in wasserlösliches Sulfat, die Hauptmenge des Eisens in unlösliches Oxyd übergeführt wird und die Hauptmenge des Nickels als unlösliches Sulfid zurückbleibt. Um dies schnell und möglichst sicher zu erreichen, ist es im Gegensatz zu dem von Hybinette empfohlenen Konzentrations-In contrast to this method, the inventors have found that without enrichment of the ore can be roasted to a concentration stone in such a way that the bulk of the copper is converted into water-soluble sulfate, the The bulk of the iron is converted into insoluble oxide and the bulk of the Nickel remains as an insoluble sulfide. In order to achieve this quickly and as safely as possible, in contrast to the concentration limit recommended by Hybinette
