Abstract

Vorrichtung zum Scheiden von Silber und/oder Kupfer aus einer Goldlegierung mit einer Anode, einer Kathode und einem Elektrolyten, dadurch gekennzeichnet, dass die Anode (7) durch die zu scheidende Goldlegierung gebildet wird, die Kathode (10) durch ein Kupferblech gebildet wird, Mittel zum Erwärmen des Elektrolyts auf mehr als 30 °C vorgesehen sind, der Elektrolyt in destilliertem Wasser gelöstes Kupfersulfat (CuSO4) ist, das sich nach einer Bindung der Kupferionen an der Kathode (10) in Schwefelsäure (H2SO4) wandelt, eine einen magnetischen Wirbel erzeugende, den sich in Schwefelsäure umgewandelten Elektrolyten mit den durch die Wirkung des Magnetfelds angereicherten Silberionen umpumpende Pumpe (5) vorgesehen ist, und ein das metallische Silber aus dem mit Silberionen angereicherten umgepumpten Elektrolyt heraus filternder Silberfilter (3) vorgesehen ist.

Figure imgaf001
A device for separating silver and / or copper from a gold alloy with an anode, a cathode and an electrolyte, characterized in that the anode (7) is formed by the gold alloy to be separated, the cathode (10) is formed by a copper sheet, Means for heating the electrolyte to more than 30 ° C, the electrolyte being copper sulfate dissolved in distilled water (CuSO 4 ), which, after binding of the copper ions to the cathode (10), converts to sulfuric acid (H 2 SO 4 ), a magnetic vortex generating electrolyte converted into sulfuric acid with pump (5) pumped by the action of the magnetic field, and a silver filter (3) filtering out the metallic silver from the silver ion-enriched circulated electrolyte is provided.
