KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Wenn man nach dem im Patent 272654 beschriebenen Verfahren zur Gewinnung des im Meerwasser enthaltenen Goldes das Meerwasser durch ein B,ett mit zerkleinertem Koks filtriert, so begegnet man dem Übelstande, daß die Arbeitsperiode sehr lang ist. Hierunter wird die Zeit verstanden, während der durch ein gegebenes Koksfilter filtriert werden muß, bis die gewünschte Anreicherung an Gold eingetreten ist.If you follow the process described in patent 272654 for obtaining the im Sea water contained gold the sea water through a bed of crushed coke filtered, one encounters the disadvantage that the working period is very long. Below is understood as the time during which a given coke filter has to be filtered, until the desired enrichment in gold has occurred.
Zur Behebung dieses hinderlichen Umstandes kann man, wie gefunden wurde, folgendermaßen vorgehen.As has been found, the following can be used to remedy this obstructive circumstance proceed.
Man läßt zu dem zu behandelnden, beispielsweise durch einen, Kanal fließenden Meerwasser eine kolloide Lösung von Kohle hinzufließen, deren Menge — z. B. 100 ecm ioprozentiger Kohlehydrosol auf 1 cbm Meerwasser — nach ihrer Adsorptionskraft und dem Goldgehalt des Meerwassers zu bemessen ist, und setzt nach einer kurzen, nach Minuten zählenden Zeit, die zur Herstellung des Adsorptionsgleichgewichtes erforderlich ist, eine solche Menge eines Eisenhydroxydsols hinzu, die zur Flockung der Kohle gerade notwendig ist. Hierauf werden die Flocken in einer geeigneten Schnellfiltrationsanlage abfiltriert.It is allowed to flow to that to be treated, for example through a canal Sea water add a colloidal solution of coal, the amount of which - z. B. 100 ecm 10% carbohydrosol in 1 cbm of sea water - to be measured according to their adsorptive power and the gold content of the seawater is, and after a short time counting after minutes, the adsorption equilibrium is established it is necessary to add such an amount of an iron hydroxide that is just necessary for the flocculation of the coal is. The flakes are then filtered off in a suitable rapid filtration system.
Das Verfahren beruht darauf, daß ein negatives Sol durch ein positives ausgeflockt wird. Daher kann an die Stelle des Ei'senhydroxydsols auch Aluminiumhydroxydsol oder ein anderes passendes positves Sol treten.The method is based on the fact that a negative sol is flocculated by a positive one. Therefore, aluminum hydroxide sol or a can also be used in place of the iron hydroxide sol kick other suitable positive sol.
Was die Herstellung von kolloiden Lösungen von Kohle anbelangt, so werden solche durch Behandeln von feinst verteilter Kohle, z. B. Lampenruß, mit äußerst verdünnten Alkalien erhalten. Auch chinesische Tusche und die als »Aquadag« bezeichneten Graphitsuspensionen fallen unter den Begriff der kolloiden Kohlelösungen. .As for the preparation of colloidal solutions of coal, so will by treating finely divided coal, e.g. B. lamp soot, with extremely dilute alkalis obtain. Also Chinese ink and the graphite suspensions known as »Aquadag« fall under the term of colloidal carbon solutions. .
