Advantages and characteristics of copper electrolytic blister copper refining equipment

Copper is widely used in electrical, light industry, machinery manufacturing, construction industry, transportation and other fields. As far as China is concerned, copper is second only to aluminum in the consumption of non-ferrous metal materials. A large number of industrial needs, coupled with the serious shortage of copper resources, in recent years, the recycling of copper has attracted attention from all walks of life. The blister copper in the mixed metal can be refined by copper electrolytic recovery and processing equipment, and can reach a purity of 99.9 to meet various industrial needs.

Copper electrolytic treatment and recovery equipment Copper electrolytic treatment and recovery equipment is a pure copper production line used to refine mixed metal blister copper into more than 99.99%.

Features:

1. The treated electrolytic waste liquid can fully meet the national emission standards;

2. The automatic control of the electrolysis process saves about 50% of labor compared to the traditional process;

3. The waste gas treatment system can recycle and produce useful chemical raw materials, increasing the benefits of enterprises;

4. The advanced automatic pole-changing electrolysis technology greatly improves the electrolysis efficiency and shortens the electrolysis cycle;

Workflow: The copper electrolysis treatment and recovery equipment mainly purifies blister copper according to the principle of copper electrolysis. The separated metal parts are cast into copper electrolytic anode plates through intermediate frequency smelting for electrolysis of copper. Because many non-ferrous metals are used in the circuit board manufacturing process , Rare earth metals and precious metals, in the conventional electrolysis, the anode is often passivated and the electrolysis cannot be carried out normally. Here, it is recommended to use a pulsed automatic pole-changing electrolysis system, which not only effectively solves the problem of anode passivation, but also helps to loosen the anode slime. The time adjustment is arbitrarily set by the cycle time relay on the panel of the electrolysis control cabinet.

The copper electrolytic treatment and recovery equipment is composed of multiple IGBT automatic power control modules and belongs 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. Anode slime, clean the anode slime, carry out reduction smelting and oxidation smelting in intermediate frequency furnace and blowing furnace, smelted precious metal alloy blocks are crushed by water, and then go through precious metal liquid making to extract, separate and refine various precious metals. In the production workshop, a tail gas absorption device with ozone must be set up in all places where tail gas is generated, and a tail liquid diversion device must be set up in all places where tail liquid is generated, and the tail liquid is diverted to the wastewater treatment workshop and discharged or reused after reaching the standard.
