| S.N. | Description | Unit | Output | Quality |
|---|---|---|---|---|
| 1 | Standard cathode copper | t/a | 400000 | Cu 99.95% |
| 2 | Crude copper sulfate | t/a | ~1000 | Cu 23% |
| 3 | Crude nickel sulfate | t/a | ~2000 | Ni1 8% |
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.
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.
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.
The system integrates cold crystallization, vacuum evaporation, solid-liquid separation, copper removal and nickel removal, and to effectively remove contaminants.
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.

This system features a high capacity designed to produce up to 400,000 tons of high-purity standard cathode copper (Cu 99.95%) annually.
The production line is highly adaptable and processes dismantled and pretreated scrap copper in various shapes and sizes, including copper wires, copper blocks, and copper granules ranging from less than 1 mm to 20 mm in diameter.
It incorporates advanced NGL furnace refining combined with stainless steel cathode electrolysis technology, utilizing natural gas as both fuel and reducing agent for an efficient and clean process.
It employs an eco-friendly dry off-gas cleaning process to treat high-temperature dust-containing exhaust. The collected dust is stored in dust bags for storage and sale, combining environmental compliance with resource recycling.
Besides high-purity cathode copper, the system outputs approximately 1,000 tons per annum (t/a) of crude copper sulfate (Cu 23%) and about 2,000 t/a of crude nickel sulfate (Ni1 8%).
To ensure stable production output and high current efficiency, the system operates on a cycle-optimized schedule consisting of a 20-day anode cycle and a 10-day cathode cycle.
