Das in nachfolgendem beschriebene Verfahren hat die leichte und billige Gewinnung des Goldes und Silbers aus Mineralien, Erzen und sonstigen goldhaltigen Stoifen zum Zweck. Dieses Verfahren wurde zunächst auf die Gewinnung des Goldes und Silbers aus Kupferstein angewendet, kann aber auch bei allen anderen gold- und silberhaltigen Stoifen, besonders schwefelhaltigen Mineralien benutzt werden.The process described below is easy and inexpensive to extract of gold and silver from minerals, ores and other gold-containing substances for the purpose. This process was first applied to the extraction of gold and silver from copper stone used, but can also be used with all other gold- and silver-containing materials, especially sulphurous minerals are used.
Aufser den angegebenen Vorzügen hat mein Verfahren noch denjenigen, dafs es die Natur der Erze, aus denen das Gold oder Silber extrahirt ist, nicht im geringsten verändert und der gold- und silberhaltige Kupferstein nach Beendigung meines Verfahrens bis auf den verlorenen Edelmetallgehalt noch der nämliche Kupferstein wie vordem ist, so dafs in seiner weiteren Verarbeitung auf Kupfer keine Veränderung einzutreten hat.In addition to the advantages mentioned, my method also has that nature the ores from which the gold or silver is extracted are not changed in the least and the gold- and silver-containing copper stone after the end of my procedure except for lost precious metal content is still the same copper stone as before, so that in his no change has to occur in further processing on copper.
Als Beispiel führe ich nun die Behandlung eines gold- und silberhaltigen Kupfersteines an.As an example, I will now cite the treatment of a copper stone containing gold and silver.
Der ohne jedes vorherige Rösten zermahlene Kupferstein wird so innig als möglich mit einer kleinen Menge pulverisirten Salmiaks gemischt. Die Menge des Salmiaks ist sehr gering und beträgt gewöhnlich 1 bis 3 pCt. des Gewichtes des Kupfersteins, doch variirt dieses Verhältnifs natürlich nach dem Gehalt des Steines an Edelmetallen.The copper stone, ground without any previous roasting, becomes as intimate as possible with a mixed a small amount of powdered salmiaks. The amount of salmiac is very small and is usually 1 to 3 pCt. the weight of the copper stone, but this ratio varies of course according to the precious metal content of the stone.
Das so bereitete Gemisch wird bei niederer Temperatur erhitzt bis zum Erscheinen der Ammoniakdämpfe, die sich reichlich bilden. Diese Heizung ist keinerlei Röstung, da die Erwärmung immer unter der Rothglut zu verbleiben Und der Stein schwarz zu bleiben hat, die Heizung überhaupt nur zur Entwickelung der Ammoniakdämpfe, nicht aber zu irgend einer Zersetzung des Schwefeleisens und -Kupfers dienen soll.The mixture prepared in this way is heated at low temperature until the appearance of the Ammonia vapors, which are produced in abundance. This heating is not roasting at all, as the Warming to stay under the red glow and the stone has to stay black, the heating in general only for the development of ammonia vapors, but not for any to decompose iron and copper.
Die Heizung kann zwar in ganz beliebiger Weise geschehen, doch ziehe ich vor, dieselbe in einer geschlossenen Muffel vorzunehmen, um die Ammoniakdämpfe zur Darstellung des Salmiaks wieder aufzufangen.The heating can be done in any way, but I prefer the same in a closed muffle to remove the ammonia vapors to represent the To collect salmiaks again.
Sobald, was nach kurzer Zeit geschieht, die Ammoniakdämpfe verschwunden sind, zeigt der Stein noch den früheren Anblick, während das Gold und Silber als Chlorverbindungen vorhanden sind. Eisen und Kupfer sind in ihrer Verbindung mit Schwefel verblieben. Es bleibt nun nur noch übrig, die Chlorverbindung von Gold und Silber durch eines der bekannten Mittel aufzulösen.As soon as, which happens after a short time, the ammonia vapors have disappeared, the shows Stone still looks earlier, while gold and silver exist as chlorine compounds are. Iron and copper remained in their connection with sulfur. It stays now only left, the chlorine compound of gold and silver through one of the known ones To dissolve funds.
Vorzugsweise benutze ich zu letzterem Zweck:For the latter purpose I prefer to use:
1. die Auflösung in unterschwefligsaurem Natron,1. The dissolution in hyposulfuric acid Soda,
2. die Fällung der Metalle als Schwefelverbindungen durch eine Zufügung von Schwefelnatrium. 2. the precipitation of the metals as sulfur compounds by adding sulfur sodium.
Beide Verfahren sind bekannt und bedürfen einer Erörterung nicht, um so weniger, als sie nicht den Gegenstand vorliegender Erfindung ausmachen.Both methods are known and do not need to be discussed, all the less so as they do not constitute the subject matter of the present invention.
