Verfahren zum Auslaugen von kalk-oder gleichzeitig auch magnesiahaltigen, rohen kupferkarbonathaltigen Erzen.
Es ist gefunden worden, dass man natürlich vorkommende Kupfererze, besonders Karbonate, wie Malachit und Lasur, bereits durch Behandlung mit einer verdünnten Lösung von Kaliumoder Natriumhydroxyd in Kupferhydroxyd umwandeln kann. Das Kupferhydroxyd ist aber bekanntlich in verschiedenen organischen Stoffen löslich, so in weinsauren Salzen ; Trauben- und Rohrzucker und ebenso auch in Glyzerin. Man kann also das Kupfer aus kupferkarbonathaltigen Erzen ausziehen, wenn man diese mit einer verdünnten, natronhaltigen Lösung einer dieser organischen Stoffe behandelt, und zwar tritt diese Lösung bei passender Zerkleinerung des Erzes bereits in der Kälte, rascher aber noch bei einer gelinden Erwärmung - auf 40 bis 50 C - ein.
Weinsaure Salze lösen dabei - wenn auch in geringen Mengen - etwas Kalk mit auf ; Zucker zeigt eine etwas verminderte Lösungsfähigkcit : am geeignetsten-auch in bezug auf die

Beide werden unter Zugabe einer geringen Menge von Kohle eingeschmolzen und nach kurzem Raffmieren in Formen gegossen.
Die Regeneration der Lösung, welch letztere, dem Kohlensäuregehalte der Kupferkarbonate entsprechend, Natriumkarbonat enthält, geschieht durch Zugabe von soviel Atznatron, dass der ursprüngliche Gehalt von 10% wieder hergestellt wird. Hat sich die Lauge nach und nach derart

Process for leaching lime or, at the same time, also magnesia-containing, raw copper carbonate-containing ores.
It has been found that naturally occurring copper ores, especially carbonates such as malachite and glaze, can be converted into copper hydroxide by treatment with a dilute solution of potassium or sodium hydroxide. But copper hydroxide is known to be soluble in various organic substances, for example in tartaric salts; Grape and cane sugar and also in glycerine. So you can extract the copper from ores containing copper carbonate if you treat them with a dilute, sodium-containing solution of one of these organic substances, and this solution occurs when the ore is appropriately crushed in the cold, but more quickly when it is gently heated - to 40 up to 50 C - a.
Tartaric acid salts also dissolve some lime, albeit in small amounts; Sugar shows a somewhat reduced solubility: most suitable - also with regard to the

containing copper and besides always a precipitation of copper oxide (about 10% of copper).
Both are melted down with the addition of a small amount of coal and, after a short refining, poured into molds.
The regeneration of the solution, which the latter contains sodium carbonate according to the carbonic acid content of the copper carbonates, is done by adding enough caustic soda to restore the original content of 10%. Has the lye gradually changed like this

ability towards the copper, just as then on the other hand no lime goes into solution.
