Features
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
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
The system integrates cold crystallization, vacuum evaporation, solid-liquid separation, copper removal and nickel removal, and to effectively remove contaminants.
Eco-Friendly 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.
