SOLUTION

Copper is a good conductor of electricity, and is used extensively to make electrical wiring and components. The purification of copper is a form of recycling. Copper is purified further using electrolysis and we call it Copper Electrorefining (electrolytic refining).
In industry this is carried out on a massive scale. The electrolytic copper production is processed in the huge copper electrolytic tank fulfilled with copper electrolytic solution. Even the best chemical method cannot remove all the impurities from
the copper, but with electrolytic refining it is possible to produce 99.99% pure copper (whatever method is used to manufacture copper from its ore, its final purification is by electrolysis).

Operational Mechanism： The process takes place in large copper electrolytic tanks filled with a specific electrolytic solution. The setup involves two main components suspended in the tank:

1. Anodes: Impure copper plates are hung by their “handles.”
2. Cathodes: Pure copper starter sheets are suspended on solid copper bars and inserted between the anodes.

When an electric current flows from the anodes through the electrolyte to the cathodes, copper ions dissolve from the anodes and plate onto the cathode sheets. Meanwhile, impurities do not dissolve; instead, they settle to the bottom of the tank as sediment (often called “anode slime”).

1.High Efficiency: By utilizing high current density and maintaining a shorter distance between anodes, the electrolytic cycle is significantly shortened, increasing throughput.

2.Cost Reduction via Automation: The system employs automatic controlling mechanisms. Compared to traditional processes, this advanced automation can reduce labor costs by approximately 50%.

3.Environmental Compliance & Value Creation: The exhaust gas treatment system is designed not only to meet national environmental requirements but also to produce useful chemicals from the waste, creating additional economic value. The tail liquid is processed to ensure it is safe and consistent with regulatory standards.
