Description

Verfahren zur Gewinnung des Goldes aus Meerwasser. Gegenüber den bekannten Verfahren zur Gewinnung des Goldes aus Meerwasser besteht das Wesen der Erfindung darin, daß das zweckmäßig bei Flut in Behälter geleitete Meerwasser mit Kohlenoxyd versetzt und das dadurch ausgeschiedene Gold durch Sink- oder Schwebestoffe, wie z. B. Ton, feingemahlene Kohle, Plankton o. dgl" zum Absetzen gebracht wird.Process for extracting gold from sea water. Compared to the known The essence of the invention is a method of extracting gold from seawater in the fact that the seawater, which is expediently directed into containers at high tide, contains carbon dioxide offset and the thereby precipitated gold by settling or suspended matter, such as z. B. clay, finely ground coal, plankton o. The like "is brought to settle.

Bei Ausführung des Verfahrens wird das Meerwasser unter Ausnutzung der ansteigenden Flut in große Behälter geleitet und während des Einströmens mit Kohlenoxyd, z. B. in der Form von Generatorgas, versetzt sowie zwecks guter Mischung hiermit in starker Bewegung erhalten.When the process is carried out, the sea water is being exploited the rising tide is fed into large containers and with it during the inflow Carbon dioxide, e.g. B. in the form of generator gas, added and for the purpose of good mixing hereby kept in strong motion.

Um das Absetzen des durch das Gas ausgeschiedenen Goldes zu beschleunigen, werden in bekannter Weise Schwebe- oder Sinkstoffe, wie z. B. Ton, feingemahlene Kohle, Seeschlick o. dgl., zugesetzt, die sich innerhalb der nächsten Tiden, während der der Behälter in Ruhe bleibt, absetzen und beim Niedersinken das ausgeschiedene Gold mit zu Boderi ziehen. Dieser mit dem ausgeschiedenen Gold angereicherte Schlamm wird, nachdem das darüberstehende Meerwasser während einer Ebbe abgelassen worden ist, vorteilhaft wiederholt als Sinkstoff zur Anwendung gebracht, bis er so viel Gold enthält, däß dessen Gewinnung nach den üblichen Goldgewinnungsverfahren eine Ausbeute verspricht. Enthält das Meerwasser selbst schon genügend Schwebe- oder Sinkstoffe, so kann auf den Zusatz besonderer Sinkstoffe verzichtet werden.To accelerate the settling of the gold precipitated by the gas, are suspended or sinking matter in a known manner, such. B. Clay, finely ground Coal, sea silt o. The like., Added, which during the next tides that the container remains at rest, put down and when it sinks down the excreted Drag gold to Boderi. This mud enriched with the precipitated gold is after the overlying sea water has been drained during an ebb is advantageously applied repeatedly as a sediment until it is so much Contains gold, that its extraction according to the usual gold extraction process a Yield promises. Does the sea water itself contain enough floating or Sinking matter, the addition of special sinking matter can be dispensed with.

Kohlenoxyd hat vor anderen ausfällenden Mitteln den Vorzug, daß seine Wirkung vollständig unabhängig ist von der jeweiligen Zusammensetzung des Meerwassers, die die goldausfällendeWirkung mancher Reagenzien, z. B. Azetylen, stark beeinflussen oder auch ganz verhindern kann.Carbon dioxide has the advantage over other precipitating agents that its Effect is completely independent of the respective composition of the sea water, the gold precipitating action of some reagents, e.g. B. Acetylene, strongly affect or prevent it entirely.

Durch den Zusatz von Sink- oder Schwebestoffen wird der ausgefällte Goldniederschlag leicht absetzbar und filtrierbar gemacht.By adding sinking or suspended matter, the precipitated Gold precipitate made easily settable and filterable.
