General
1. Sources of Scrap Copper Granules and Copper Powder
Scrap copper granules and copper powder mainly come from the following sources:
- Waste wire recycling: separating copper from the outer plastic in wires with a crusher to extract high-purity red copper granules.
- Printed circuit board (PCB) recycling: crushing, electrostatic sorting and grinding waste PCBs to produce powder containing high-purity copper.
- Waste copper solution recycling: extracting copper sulfate from spent copper solution used in the PCB industry, and further refining it into high-purity metallic copper.
2. Recycling Technologies and Processes
- Wire crushing and sorting technology:
- Using professional equipment (such as SEDA wire crushers) to rapidly crush waste wire, separating high-purity red copper granules and recycling the outer plastic.
- PCB recycling technology:
- Waste PCBs are crushed to a particle size of 6-10mm, then further ground to below 0.83mm, and separated into metal and non-metal materials using an air classifier to extract crude copper products with a content exceeding 80%.
- Waste copper solution recycling technology:
- Using electrolysis to extract metallic copper with purity exceeding 99.5% from waste copper solution, while purifying the spent solution into pure water, achieving efficient resource recycling.
After crushing, waste copper wire usually forms copper granules or copper powder. Depending on the processing equipment and process, purity can reach 99.9%. Packaging methods are generally as follows:
- Bags:
- Moisture-proof, dust-proof plastic woven bags or vacuum bags.
- Each bag typically weighs 25kg or 50kg for easy transport and storage.
- Drums:
- Sealed metal or plastic drums, suitable for high-purity copper granules to prevent oxidation.
- Big bags:
- Large ton bags (1 ton/bag) for bulk transport, suitable for export or large-scale recycling companies.
