Verfahren zur Darstellung von Grünspan aus Kupfererzen.
Aus gewissen Kupfererzen, die man zur Zeit nur durch Extraktion mittels Mineralsäuren verarbeitet, kann man wertvollere Produkte erhalten wie bisher, wenn man zur Extraktion Essigsäure verwendet. Man erhält dabei Grünspan in kristallinischer Form.
Das Vorfahren wird dabei in der Weise ausgeübt, dass man geeignete oxydische oder kupferkarbonhattige Erze mit passend verdünnter Essigsäure behandelt, beispielsweise einer 15/nigen Säure. Aus der dabei erhaltenen Rohlauge entfernt man zunächst die freie Essigsäure durch Saturation oder Destination und scheidet dann die Verunreinigungen, wie Eisen, Tonerde, Kalk u. s. w., durch Ausfällen mittels Natrium-Kalium oder Amoniuiukarbonat bsszw. deren Oxydhydrate aus. Aus der zurückbleibenden Lösung kann man den Grünspan durch Auskristallisation erhalten.

Process for the preparation of verdigris from copper ores.
From certain copper ores, which are currently only processed by extraction with mineral acids, more valuable products can be obtained than before if acetic acid is used for the extraction. Verdigris is obtained in crystalline form.
The process is carried out in such a way that suitable oxidic or copper-carbon-containing ores are treated with suitably dilute acetic acid, for example a 15% acid. From the resulting raw liquor, the free acetic acid is first removed by saturation or destination and then the impurities such as iron, clay, lime and the like are separated. s. w., by precipitation with sodium-potassium or ammonium carbonate or their oxide hydrates. The verdigris can be obtained from the remaining solution by crystallization.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
