The final quality of cathode copper depends on the operation and maintenance level of the electrolytic cell in copper electrolytic refining. To produce high-purity, physical specification-compliant Grade A copper, the electrolytic cell must be managed in a meticulous and standardized manner.

1. Refined operation is the core

   Electrolyte parameter control: Ensure that copper ion concentration, acidity, temperature, and additives are within the optimal process range. Temperature fluctuations affect the cathode deposition structure, and an imbalance in additives can cause surface roughness, nodules, or brittle cracks.

   Circulation and Filtration: Sufficient electrolyte circulation ensures uniform ion concentration, avoids concentration polarization, and makes copper deposition dense and smooth. Efficient continuous filtration removes suspended impurities and prevents the formation of "particles" or "lumps" on the cathode plate surface.

   Slot surface management: control the pole pitch; too small will easily cause short circuit, while too large will increase energy consumption and slot voltage; regularly check and eliminate short circuit, and keep the conductive contact points clean and tight; when removing the pole piece from the slot, the starting pole piece must be flat, vertical, and accurately aligned, and be handled with care when removing it from the slot.

2. Systematic maintenance is the cornerstone

   Tank cleaning and tank body maintenance: Stop the tank as planned to remove anode mud, check the tank body anti-corrosion layer, and prevent leakage.

   Equipment and accessories maintenance: Regularly calibrate the anode plate to ensure uniform thickness and no burrs; regularly grind and polish the surface of the cathode mother plate to ensure it is smooth and flat; check the circulation pipeline and maintain the heater to ensure stable heating supply.

Improving the quality of cathode copper is a systematic project that requires close integration of refined operations and systematic maintenance to reduce quality fluctuations, produce high-purity cathode copper that meets the needs of the high-end market, and enhance the core competitiveness of the enterprise.
