Es ist' wiederholt vergeblich versucht worden, die Spuren von Edelmetallen, insbesondere von Gold, die das Meerwasser enthält, daraus durch Reduktionsmittel, wie Zinnchlorür, Ferrosulfat u. a., niederzuschlagen. Ein wirklicher Erfolg wurde auch dann nicht erreicht, als zum Mitreißen des metallischen, in kolloidaler Form erscheinenden Niederschlages pulverige Stoffe zugesetzt wurden, nämlichIt has' repeatedly been tried in vain to trace the traces of precious metals, in particular from gold, which the sea water contains, from it through reducing agents such as tin chloride, Ferrous sulphate, among others, to precipitate. Even then it was not a real success reached than to entrain the metallic precipitate, which appears in colloidal form powdery substances were added, namely
ίο Kalk, Ton, Sand, Eisenoxyd, zeolithische Silikate, Schlacken und Asche. Ferner hat man versucht, die Reduktionsmittel, wie Zinnchlorür, Ferrosulfat usw., wegzulassen und Meerwasser bloß mit den genannten pulverigen Stoffen in Berührung zu bringen. In diesem Falle findet an der Oberfläche derselben zweifellos eine Adsorption der im Meerwasser gelösten Goldsalze statt. Allein es ist mit den genannten Stoffen nicht möglich, eine solche Anreicherung des Goldes am Adsorbens zu erzielen, daß eine metallurgische Verarbeitung der Adsorptionsverbindung lohnend wäre.ίο lime, clay, sand, iron oxide, zeolitic silicates, Slag and ash. Attempts have also been made to use reducing agents such as tin chloride, Ferrous sulfate etc., omit and only add seawater with the powdery substances mentioned To bring touch. In this case there is undoubtedly one on the surface of it Adsorption of the gold salts dissolved in the sea water takes place. Alone it is with those mentioned Substances not possible to achieve such an enrichment of the gold on the adsorbent that metallurgical processing of the adsorbent compound would be worthwhile.
Wir haben nun in der Kohle ein Adsorptionsmittel gefunden, das den bisher vorgeschlagenen und oben genannten bei weitem überlegen ist. Wenn es auch qualitativ bekannt ist, daß Kohle Goldsalze adsorbiert, so hatte man doch keinen Anhaltspunkt, wie groß die "Wirkung bei sehr hohen Verdünnungen sein würde, um so weniger, als das für mittlere Verdünnungen gültige Adsorptionsgesetz noch nie für so hohe Verdünnungen geprüft wurde, wie sie hier in Frage kommen, und man daher nicht wissen konnte, wie sich die Adsorption der Salze der Edelmetalle in solchen Verdünnungen wie im Meerwasser gestalten würde. In dem überraschend großen Betrage der von uns gemessenen Adsorptionswirkung der Kohle auf hochverdünnte Lösungen der Salze der Edelmetalle — außer Gold kommen auch Silber und Platinmetalle in Betracht, die sich übereinstimmend verhalten — muß ein neuer technischer Effekt erblickt werden, denn jetzt erst ist ein Weg erschlossen, um die im Meerwasser enthaltenen Edelmetalle derart anzureichern, daß ihre Adsorptionsverbindungen metallurgischer Verarbeitung zugänglich werden.We have now found in coal an adsorbent similar to that previously proposed and is far superior to the above. Although it is known qualitatively that coal adsorbs gold salts, so you had no clue how big the "effect" at very high dilutions would be, all the less since the law of adsorption, which is valid for medium dilutions, has never been used for such high dilutions it was examined how they come into question here, and therefore one could not know how to do it make the adsorption of the salts of the precious metals in such dilutions as in sea water would. In the surprisingly large amount of the adsorption effect of coal on highly diluted solutions measured by us the salts of precious metals - besides gold, silver and platinum metals are also possible, which behave in unison - a new technical effect must be seen because only now a way has been opened up to those contained in the sea water Enrich precious metals in such a way that their adsorption compounds are metallurgical processing become accessible.
Die Kohle ist in ihren verschiedenen Formen, wie Tierkohle, Holzkohle, ölkoks, Ruß, gepulverte Steinkohle usw., als Adsorbens für die in Frage kommenden Metallsalze geeignet. Mit einer Lösung, die 10 mg Gold im Kubikmeter als Natriumaurichlorid enthält, steht z. B. gepulverte Holzkohle im Gleichgewicht, wenn das Holzkohlenpulver 0,5 Prozent Gold adsorbiert enthält.The coal is in its various forms, such as animal coal, charcoal, oil coke, soot, powdered coal, etc., suitable as an adsorbent for the metal salts in question. With a solution that contains 10 mg of gold per cubic meter as sodium aurichloride, stands z. B. Powdered charcoal in equilibrium when the charcoal powder is 0.5 percent gold contains adsorbed.
Da für die technische Wirkung eine sehr große Oberflächenentwicklung des Adsorbens das wesentliche ist, so läßt sich voraussehen, daß an Stelle der Kohle auch andere Stoffe mit sehr großer Oberfläche, . z. B. Faserstoffe, wie Holzschliff, und mineralische Stoffe, wie Kieselgur, kolloide Hydroxyde des Eisens, Aluminiums und anderer Metalle, Gipspulver, Zementpulver und ähnliches, treten können.As a very large surface development of the adsorbent for the technical effect The essential thing is, it can be foreseen, that instead of coal there will also be other substances with a very large surface,. z. B. fibrous materials, such as wood pulp, and mineral materials, such as Diatomaceous earth, colloidal hydroxides of iron, aluminum and other metals, gypsum powder, Cement powder and the like.
Das Verfahren, das sich auf die soeben zahlenmäßig angegebene Adsorptionswirkung der Kohle gründet, besteht nun einfach darin, eine Lösung, die Edelmetallsalze in sehr geringer Konzentration enthält, z. B. Meerwasser, mit Kohle in feiner Verteilung in Berührung zu bringen. Dies kann so geschehen, daß das Meerwasser durch einen Filterturm, der mit zerkleinerter Kohle angefüllt ist,The process that affects the adsorption effect just given The coal foundation now consists simply of a solution that salts precious metal in very little Contains concentration, e.g. B. sea water, in contact with coal in fine distribution bring to. This can be done so that the sea water through a filter tower, which is filled with crushed coal,
ίο fließt oder durch einen Bottich, dessen Boden mit dem Adsorbens bedeckt ist, oder daß das Meerwasser durch Nutschen gesaugt wird, auf denen zerkleinerte Kohle ausgebreitet wird usw. Hat sich dieselbe mit den zu absorbierenden Stoffen gesättigt, so wird sie entfernt und durch frische Mengen ersetzt. Nach vollzogener Adsorption kann man die Kohle verbrennen und aus der Asche oder Schlacke die Edelmetalle in bekannter Weise darstellen.ίο flows or through a vat whose bottom is covered with the adsorbent, or that the sea water is sucked up by suction to which crushed charcoal is spread, etc. Has the same with those to be absorbed When substances are saturated, they are removed and replaced by fresh amounts. After completed The coal can be burned by adsorption and the precious metals can be produced in a known manner from the ashes or slag.
Nicht zu verwechseln mit der bisher ausNot to be confused with the one made so far
genutzten Adsorptionskraft ist ihre wohlbekannte Reduktionswirkung. Diese kommt hier nicht in Betracht, da zur Reduktion der Edelmetallsalze an hochverdünnter Lösung durch Kohle bei gewöhnlicher Temperatur die 25 Dauer der Einwirkung von ganz anderer Größenordnung sein müßte, als die Berührungs: zeit von Kohle und Lösung bei einer Filtra- . tion beträgt.The adsorptive power used is its well-known reducing effect. This does not come into consideration here, since the reduction of the noble metal salts of highly dilute solution by carbon at ordinary temperature, the 25 period of exposure would have to be of an entirely different order of magnitude than the touch: time of coal and solution at a filtration. tion is.
