Wird Schwefelkupfer in feurigflüssigem Zustande mit überhitztem Wasserdampf behandelt, so werden beide Körper hierdurch zersetzt. Der Sauerstoff des Wassers verbindet sich zum gröfsten Theile mit dem Schwefel des Schwefelkupfers zu schwefliger Säure und zu einem kleinen Theile mit dem Kupfer zu Kupferoxydul. Der Wasserstoff wirkt reducirend auf das Kupferoxydul und führt dies zurück in metallisches Kupfer.If copper sulphide is treated in a fiery liquid state with superheated steam, so both bodies are thereby disintegrated. The oxygen in the water connects to the the largest part with the sulfur of the copper sulphide to form sulphurous acid and to one small parts with the copper to form copper oxide. The hydrogen has a reducing effect the copper oxide and converts this back into metallic copper.
Leitet man in einen Tiegel, der schmelzendes Schwefelkupfer enthält, überhitzten Wasserdampf, so wird durch die oben beschriebenen Processe das Schwefelkupfer in metallisches Kupfer übergeführt, welches noch einen Theil Kupferoxydul aufgelöst enthält.If you pass superheated steam into a crucible that contains melting copper sulphide, Thus, through the processes described above, the copper sulphide turns into metallic Transferred to copper, which still contains a part of dissolved copper oxide.
Dieser Rest Kupferoxydul wird durch Rühren des geschmolzenen Kupfers mit Birkenholz durch Reduction in Kupfer übergeführt. Ist das Schwefelkupfer in metallisches Kupfer verwandelt, so hört die Zersetzung des überhitzten Wasserdampfes auf, was man unter anderem auch daran erkennt, dafs die durch Wasserstoff erzeugte Flamme verschwindet.This rest of copper oxide is made by stirring the molten copper with birch wood converted into copper by reduction. Is the copper sulphide in metallic copper transformed, the decomposition of the superheated water vapor stops, what is called It can also be recognized by the fact that the flame produced by hydrogen disappears.
