Description
Die Erfindung betrifft eine Vorrichtung zum Scheiden von Silber und/oder Kupfer aus einer Goldlegierung mit einer Anode, einer Kathode und einem Elektrolyten.The invention relates to a device for separating silver and / or copper from a gold alloy with an anode, a cathode and an electrolyte.
Altgold besteht üblicherweise aus einer Goldlegierung mit Silber und/oder Kupferanteilen. Es besteht daher Bedarf an einer Vorrichtung, die es in einfacher Weise ermöglicht, das Silber oder Kupfer aus einer Goldlegierung, dessen Goldanteil 33% nicht übersteigt, zu scheiden.Old gold usually consists of a gold alloy with silver and / or copper shares. Therefore, there is a need for a device that readily enables the gold or copper to be deposited from a gold alloy whose gold content does not exceed 33%.
Die
Erfindungsgemäß wird die genannte Aufgabe dadurch gelöst, dass die Anode durch die zu scheidende Goldlegierung gebildet wird, die Kathode durch ein Kupferblech gebildet wird, Mittel zum Erwärmen des Elektrolyts auf mehr als 30°C vorgesehen sind, der Elektrolyt in destilliertem Wasser gelöstes Kupfersulfat ist, das sich nach Bindung der Kupferionen an der Kathode in Schwefelsäure wandelt, einen magnetischen Wirbel erzeugende, dem sich in Schwefelsäure umgewandelten Elektrolyten mit den durch die Wirkung des Magnetfelds angereicherten Silberionen umpumpende Pumpe vorgesehen ist und ein das metallische Silber aus dem mit Silberionen umgepumpten Elektrolyt heraus filternder Silberfilter vorgesehen ist.According to the invention, the stated object is achieved in that the anode is formed by the gold alloy to be separated, the cathode is formed by a copper sheet, means are provided for heating the electrolyte to more than 30 ° C., the electrolyte is copper sulfate dissolved in distilled water, which, after binding of the copper ions at the cathode, converts to sulfuric acid, provides a magnetic vortex-generating pump circulating in sulfuric acid with pumps pumped by the action of the magnetic field and filtering out the metallic silver from the electrolyte circulated with silver ions Silver filter is provided.
Vorzugsweise ist die Pumpe ist eine Magnetkupplungspumpe.Preferably, the pump is a magnetic drive pump.
Der Silberfilter besteht vorzugsweise aus in einem gesonderten Raum hängend angeordneten Kupferplatten.The silver filter is preferably made of copper plates suspended in a separate space.
Die Anode
Die Erfindung wird im Folgenden anhand einer Zeichnung erläutert. Dabei zeigt die einzige Figur eine schematische Ansicht der Vorrichtung.The invention will be explained below with reference to a drawing. The single figure shows a schematic view of the device.

Von der Anode
Die erwärmte Schwefelsäure ist in der Lage, das Silber aus der Anode
Die zu diesem Zweck eingesetzte Magnetkupplungspumpe
Andere Metalle wie Palladium, Zink, Nickel, Indium verbleiben in der Lösung. Wenn zunehmend Fremdmetalle außer Kupfer gelöst sind, sinkt der Wirkungsgrad des Elektrolyten, so dass er ausgetauscht werden muss. Der verbrauchte Elektrolyt kann durch Kristallisation von Kupfersulfat regeneriert werden. Die anderen gelösten Metalle können ebenfalls durch Kristallisierung der Salze getrennt werden.Other metals such as palladium, zinc, nickel, indium remain in the solution. When foreign metals are increasingly dissolved except copper, the efficiency of the electrolyte decreases, so it must be replaced. The spent electrolyte can be regenerated by crystallization of copper sulfate. The other dissolved metals can also be separated by crystallization of the salts.
Bei einer optimalen Einrichtung des Kreislaufs sind daher nur destilliertes Wasser und Strom nach- bzw. zuzuführen.With an optimal device of the circuit, therefore, only distilled water and electricity should be supplied or supplied.
Wenn alle Metalle herausgelöst sind, bleibt auf dem Boden
Die Erfindung ermöglicht es, auf kleinstem Raum und optimaler Energieeffizienz Kupfer und Silber aus einer Goldlegierung zu scheiden.The invention makes it possible to separate copper and silver from a gold alloy in the smallest space and with optimum energy efficiency.
