Are you looking to scale your advanced metallurgy capabilities or produce Ultra-High Purity (UHP) copper for semiconductor and high-tech applications?
The Zhengzhou Jinquan 6N High-Purity Copper Electrolytic Cell is an industry-leading electrochemical refining system designed to refine standard copper cathodes or scrap into ultra-pure 99.9999% (6N) copper. Built with corrosion-resistant materials, intelligent process controls, and high-efficiency circulation mechanics, this electrolytic cell delivers uncompromised purity and reliable continuous operation.
Proven Industrial Deployment: This advanced system has already been put into production in Shanghang, Fujian Province—a major hub for China's non-ferrous metal industry—demonstrating stable, high-yield operational success at scale.
While standard electro-refined copper typically reaches 4N (99.99%) purity, critical high-tech industries require 6N (99.9999%) grade material. At 6N purity, total impurity content—including metallic elements and gases like oxygen, hydrogen, and sulfur—is reduced to parts-per-million (ppm) or sub-ppm levels.
6N copper is essential for:
Semiconductor Sputtering Targets: Thin-film deposition in microchip and IC manufacturing.
High-Frequency & Optical Electronics: Superconductors, high-end audio cables, and aerospace wiring.
Photovoltaic & Solar Cells: High-efficiency interconnects and evaporation materials.
Research Laboratories: Analytical standards and custom chemical synthesis.
Designed specifically for multi-stage electro-refining, the cell utilizes optimized electrolyte flow dynamics (parallel-flow / forced circulation) to eliminate localized concentration polarization. This guarantees uniform copper deposition on the cathode while preventing unwanted impurity co-deposition.
To handle aggressive acid media and maintain zero contamination:
Cell Body: Fabricated from high-performance Polypropylene (PP) or FRP lined with chemical-resistant polymers.
Conductive Busbars: High-conductivity Titanium-clad copper busbars that minimize voltage drops and prevent localized oxidation.
Equipped with an intuitive touch-screen interface, the PLC system continuously monitors:
Real-time cell voltage and current density.
Electrolyte temperature, acidity, and flow rates.
Busbar temperature and safety interlocks.
In the event of short circuits or thermal abnormalities, the system automatically adjusts parameters or triggers safety interlocks to protect equipment and production output.
Featuring a closed exhaust-hood structure, the unit captures and condenses acidic mist, maintaining a safe working environment and preventing workplace corrosion while complying with international environmental standards.
