In today's world, where resources are becoming increasingly scarce and sustainable development is a global consensus, we offer you an industry-leading complete production line solution for the regeneration of high-purity cathode copper from waste scrap copper. This production line integrates cutting-edge technology with mature processes, turning various types of waste copper into valuable resources, producing high-quality cathode copper that meets or even exceeds market standards. It helps clients achieve a win-win situation in both economic benefits and environmental responsibility.
This production line adopts advanced NGL furnace refining + stainless steel cathode electrolysis technology. Using dismantled and pretreated copper wires, copper blocks, copper granules, and other copper scrap as the main raw materials, it produces high-purity cathode copper. With an annual production capacity of up to 400,000 tons, the process covers the entire cycle from scrap copper recovery, melting, and casting to electrolytic refining, achieving efficient utilization and recycling of copper scrap.

Efficient resource reutilization: Capable of processing high-grade copper scrap in various shapes and sizes, including copper wires, copper blocks, and copper granules ranging from less than 1 mm to 20 mm in diameter. The system transforms scrap copper into high-purity cathode copper, enabling high value-added recovery, conserving resources, and reducing production costs.
Advanced smelting technology: The whole smelting process is composed of charging and melting, oxidation, reduction and casting. It employs oxy-fuel combustion with natural gas as both the fuel and reducing agent, ensuring a clean and environmentally friendly operation. The smelting process is characterized by short melting time of materials, high redox efficiency, energy saving and consumption reduction, little environmental pollution.
Cycle-optimized design for improved output efficiency: The system operates with a 20-day anode cycle and a 10-day cathode cycle, allowing for orderly replacement. This ensures high current efficiency and stable production output.
Multiple impurity removal processes: The system integrates cold crystallization, vacuum evaporation, solid-liquid separation, copper removal and nickel removal, and to effectively remove contaminants.
Efficient and eco-friendly dry process for off-gas cleaning: The system uses a dry process to treat high-temperature dust-containing off-gas produced by the smelting furnace. The dust collected by each device of the dust collection system is stored in dust bags for storage and sale achieving both resource recycling and economic benefits.
