Description

Verfahren zum elektrolytischen Abscheiden von Gold Bei der elektrolytischen Abscheidung, insbesondere Raffination von Gold konnten bisher als Kathoden nur Mutterbleche aus Walzgold verwendet werden. Das @darauf niedergeschlagene samtartige Elektrolytgold wurde im weiteren Verlauf der bekannten Goldggewinnungsverfahren gemeinsam mit dem Kathodenmaterial eingeschmolzen. Es war somit für jede Einzelabscheidungeine neue Kathode erforderlich, die demnach nur ,einmal verwendet werden konnte und deren umständliche Vorbereitungsarbeiten, wie z. B. das Walzen des kompakten Goldes zu dünnen Blechen, leine wesentliche Komplizierung des Betriebes und eine Erhöhung der Kosten zur Folge hatten.Process for the electrodeposition of gold In the electrolytic Until now, the only cathodes that could be used for separating gold, especially refining, were mother sheets made of rolled gold can be used. The velvety electrolyte gold deposited on it was in the further course of the known gold extraction process together with the Cathode material melted down. It was therefore a new one for each individual separation Cathode required, which therefore could only be used once and their cumbersome preparatory work, such as B. the rolling of the compact gold thin sheet metal, a substantial complication of the operation and an increase the cost.

Um diese Nachteile zu vermeiden, wurden Versuche durchgeführt mit dem Ziele, das bisher für die Kathoden verwendete Gold durch andere Stoffe zu ersetzen. Es wurde fiestggestellt, daß Metalle bzw. Legierungen, wie Silber, Nickel, V2a-Stahl, Eisen, Kupfer, Blei, für die vorgenannte Verwendung nicht geeignet sind. Es wurde gefunden, daß bei .der elektrolytisgchen Abscheidung von Gold Überraschenderweise eine durchaus einwandfreie Goldabscheidung erreicht wird, wenn an Stelle von Goldkathoden solche aus Niob bzw.' aus Legierungen dieses Metalles verwende werden.In order to avoid these disadvantages, tests were carried out with the aim of replacing the gold previously used for the cathodes with other materials. It was stated that metals or alloys such as silver, nickel, V2a steel, Iron, copper, lead, are not suitable for the aforementioned use. It was found that in the case of the electrolytic deposition of gold, surprisingly a perfectly flawless gold deposition is achieved if instead of gold cathodes those made of niobium or ' made of alloys of this metal.

So konnte z. B. bei der Anwendung von Niobble.ch ,als Kathodenmaterial das niedergeschlagene Elektrolytgold in zusammenhängender Form abgezogen werden. Das vorggtnannte Metall bietet auch im Vergleich mit Gold sowohl hinsichtlich der Anschaffungs: kosten ,als auch in bezug auf die Beschaffenheit besondere Vorteile.So could z. B. when using Niobble.ch, as cathode material the deposited electrolyte gold can be withdrawn in a coherent manner. The aforementioned metal also offers in comparison with gold both in terms of Acquisition: costs, as well as special advantages in terms of quality.
