Copper electrolysis equipment treatment process
Copper electrolytic treatment and reuse equipment is mainly based on the principle of copper electrolysis to purify blister copper. The separated metal part is cast into copper electrolytic anode plate through intermediate frequency smelting for electrolytic copper. Because many non-ferrous metals and rare earths are used in the circuit board manufacturing process For metals and precious metals, in conventional electrolysis, the anode is often passivated and the electrolysis cannot be carried out normally. It is recommended to adopt a pulse automatic electrode change electrolysis system, which not only effectively solves the problem of anode passivation, but also helps to loosen the anode mud. The time adjustment is arbitrarily set on the cycle time relay on the panel of the electrolysis control cabinet.
Copper electrolysis treatment and reuse equipment is composed of multiple IGBT automatic power control modules, which belong to digital pulse power equipment. A semi-automatic vertical mold is used when casting the anode plate. In order to shorten the electrolysis cycle, the thickness of the anode is generally controlled at 10 mm to 30 mm. In the electrolysis, the cathode of the electrolytic cell is electrolytically pure copper, and the anode contains precious metals such as gold, silver, platinum, and palladium. Anode slime is cleaned, reduction smelting and oxidation smelting are carried out in an intermediate frequency furnace and a converting furnace. The smelted precious metal alloy block is water crushed, and then the precious metal is produced to extract, separate and refine various precious metals. In the production workshop, exhaust gas absorption devices with ozone must be set up in all places where tail gas is produced, and tail liquid diversion devices must be set up in all places where tail liquid is produced to divert the tail liquid to the wastewater treatment workshop for treatment and discharge or use after reaching the standard.
