Description
KAISEFIiCHESKAISEFIiCHES
Die vorliegende Erfindung bezweckt ein Verfahren zur Extraktion von Kupfer und anderen Metallen mit Ausnahme von Gold, wie Blei, Zink usw., aus den Rückständen gerösteter und solche enthaltender Pyrite.The present invention aims at a method for the extraction of copper and others Metals with the exception of gold, such as lead, zinc, etc., from the residues of roasted and pyrites containing them.
Gegenüber den bisher benutzten Verfahren gewährt das vorliegende neue Verfahren den Vorteil, eine vollkommenere Extraktion des Kupfers mit geringeren Kosten zu ermögliehen und weiter auch noch die Extraktion fast der Gesamtheit an solchen Metallen, wie Blei, Zink usw., während die alten Verfahren diese anderen Metalle zurücklassen, was bei der Metallurgie des Eisens Übelstände mit sich bringt.Compared to the previously used method, the present new method grants the Advantage of allowing a more complete extraction of the copper at a lower cost and also the extraction of almost all metals such as Lead, zinc, etc, while the old processes leave these other metals behind what is at the metallurgy of iron brings with it evils.
Das den Gegenstand der vorliegenden Erfindung bildende Verfahren besteht darin, daß das geröstete Pyrit durch Chlor in statu nascendi in einer sauren Flüssigkeit bei einer Temperatur von ungefähr 70 bis 80 ° behandelt wird. Hierbei gehen das Kupfer und die anderen Metalle, wie Blei, Zink usw., dann in Lösung, und man braucht sie nur abzulassen und die Rückstände zu waschen.The method forming the subject of the present invention consists in that the roasted pyrite by chlorine in statu nascendi in an acidic liquid at a Temperature of about 70 to 80 ° is treated. This is where the copper and the others go Metals like lead, zinc, etc., then in solution and all you have to do is drain them and wash off the residue.
In' folgendem werde ein Beispiel für das praktische Verfahren gegeben.An example of the practical procedure is given below.
Man mischt die Rückstände trocken mit 2 bis 5 Prozent Calcium hypochlorite oder man feuchtet sie mit alkalischen Hypochloritlösungen oder mit solchen Lösungen alkalischer Erden an, bringt sie in Behälter und besprengt mit Schwefelsäure oder mit verdünnter lauwarmer Salzsäure (man benutzt die Salzsäure, wenn Blei vorhanden- ist). Dann läßt man während 12 bis 24 Stunden reagieren, zieht die Flüssigkeit ab und wäscht mit verdünnter lauwarmer Säure und dann mit Wasser. Es bleiben dann nur noch Spuren fremder Metalle in den Rückständen.One mixes the residue dry with 2 to 5 percent calcium hypochlorite or one moisturizes them with alkaline hypochlorite solutions or with such solutions more alkaline Earth, put them in containers and sprinkled with sulfuric acid or with diluted lukewarm hydrochloric acid (hydrochloric acid is used when lead is present). Then lets if you react for 12 to 24 hours, the liquid is drawn off and washed with dilute lukewarm acid and then with water. Then only traces of foreign metals remain in the residues.
