Die Aufschließung des Kupferkieses geschieht gewöhnlich durch Röstung oder Verwitterung, d. h. durch Behandlung mit viel Luft,- meist unter Erwärmung; dadurch werden Sulfate von Kupfer und Eisen, schließlich Oxyde und Kupfersulfür gebildet.The breakdown of the copper gravel is usually done by roasting or weathering, d. H. by treatment with a lot of air, - usually with warming; thereby become Sulphates formed by copper and iron, and finally oxides and copper sulphates.
Die hier vorgeschlagene Aufschließung des Kupferkieses besteht in der Behandlung ohne Luftzufuhr unter Erwärmung. DadurchThe decomposition of the copper pebbles proposed here consists in the treatment without Air supply with heating. Through this
ίο wird unter Abtreibung des lose gebundenen Schwefels der Kupferkies in eine andere, wahrscheinlich Kupfersulfür enthaltende chemische Verbindung übergeführt, welche durch die in der Hüttenindustrie bereits verwendeten oder vorgeschlagenen Lösungsmittel viel leichter und energischer angegriffen wird als der natürliche Kupferkies. Durch diese Aufschließung wird daher eine neue, vorteilhaftere Art der Auslaugung des Kupfergehalts ermöglicht.ίο is having abortion of the loosely tied Sulfur of the copper pyrites into another, probably containing copper sulphate chemical compound transferred by those already used in the metallurgical industry or proposed solvent is attacked much more easily and more vigorously than the natural copper pebbles. This unlocking therefore creates a new, more advantageous one Allows type of leaching of the copper content.
Das wichtigste Kennzeichen dieser Aufschließung bildet die Schnelligkeit, mit welcher sie vor sich geht; sie nimmt nämlich meist nur Y2 Stunde in Anspruch und ist beendet, wenn der lose Schwefel abgetrieben ist. Die Abtreibung und Gewinnung des losen Schwefels ohne Luftzufuhr bei Kiesen, wie sie bei dem vorliegenden Verfahren auch stattfinden soll, ist zwar bekannt; es war aber bisher nicht bemerkt worden, daß dadurch der Kupferkies für die bekannten Laugungsmittel der Hüttenindustrie laugbar wird; an die Abtreibung des losen Schwefels war daher bis jetzt die Auslaugung des Kupfers nicht geknüpft worden.The most important characteristic of this unlocking is the speed with which it takes place; it usually only takes 2 hours and is over when the loose sulfur has been driven off. The abortion and extraction of loose sulfur without air supply in gravel, as it is also supposed to take place in the present process, is known; but it had not yet been noticed that this made the copper pebbles leachable for the known leaching agents of the metallurgical industry; the leaching of copper had therefore not been linked to the abortion of the loose sulfur.
Wird durch Zufall oder Absicht während dieser Aufschließung etwas Luft zugeführt, z. B. durch kleine Öffnungen in dem das Erz enthaltenden Gefäß oder Ofen, aber die kurze Erhitzung beibehalten, so bleibt die Wirkung auf den Kupferkies dieselbe; nur der abgetriebene Schwefel wird, zum Teil oder ganz, in schweflige Säure umgewandelt.If by chance or on purpose some air is added during this decomposition, z. B. through small openings in the vessel or furnace containing the ore, but the If the heating is maintained for a short time, the effect on the copper pebbles remains the same; only some or all of the sulfur driven off is converted into sulphurous acid.
