Definitions

the invention relates to a device for separating silver and / or copper from a gold alloy with an anode, a cathode and an electrolyte.
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%.
the CH 426278 A already discloses a process for the electrolytic precipitation of silver-gold alloys.
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 the pumped silver ions enriched by the action of the magnetic field, and filtering out the metallic silver from the electrolyte pumped with silver ions Silver filter is provided.
the pump is a magnetic drive pump.
the silver filter preferably consists of a copper plate suspended in a separate space.
the anode 7 can be suspended in a container 8 perforated on one side from an acid-resistant material, at the bottom of which the divisional gold 6 accumulates.
the invention will be explained below with reference to a drawing.
the single figure shows a schematic view of the device.
a tub 1 is in a (not shown) heat sink, which ensures a process temperature of 35 ° C.
an electrolyte-forming solution of copper sulfate in distilled water In the tub 1 is an electrolyte-forming solution of copper sulfate in distilled water.
An anode 7 is formed by the noble metal alloy to be separated, it hangs in a laterally perforated cup. The anode is connected in the usual way with a 12 V DC power source.
the cathode 10 is formed by a copper sheet and is connected to the negative pole of the power source. When a voltage is applied between the anode and the cathode, a current flows through which electrolytic copper 9 deposits on the cathode 10.
Copper ions migrate from the anode 7 to the cathode 10.
the copper 10 is released from the anode. Once the copper ions are bonded to the cathode 10, the bath transforms from a copper sulfate solution to a sulfuric acid solution.
the heated sulfuric acid is capable of dissolving the silver from the anode 7.
the generated silver ions are deposited on the cathode only when the solution is saturated.
the silver ions behave diamagnetically, so they can be distracted by a magnetic field.
the magnetic coupling pump 5 used for this purpose generates a magnetic vortex which causes the silver ions to rotate around the pump.
the silver ions are sucked off and pumped into a silver filter 3 which is suspended in a separate space in which copper plates 2 hang.
the silver filter 3 consists in the illustrated embodiment of a separate container made of an acid-resistant material. Due to the electrochemical series of voltages, silver ions impinging on copper atoms form metallic silver 4, which deposits on the copper plates 2. The copper goes into solution and runs over the edge of the container 3 back into the tub.
the fine gold remains on the ground in the form of a black powder.
the recovered gold powder and the recovered silver powder are washed in distilled water and melted.
the invention makes it possible to separate copper and silver from a gold alloy in the smallest space and with optimum energy efficiency.
