Process & Machinery
Closed‑loop hydrometallurgy
- Brick‑lined or SS316 reactors dissolve copper from residues and PCB feed in controlled acid conditions.
- Filtration and evaporation crystallize high‑purity CuSO4; mother liquor is recovered and reused.
- Near zero‑liquid discharge via recirculation lowers effluent and operating cost.
- Gravity separation and powdering steps improve metal yield before solution processing.
Air, effluent, and utility systems
- Multi‑stage scrubbers capture process fumes and particulates to meet compliance.
- Dedicated ETP treats acidic streams; water is recycled back to process.
- Independent cooling loops stabilize reactor and crystallizer temperatures.
- Storage tanks sized for acids and mother liquor ensure continuous operations.
Integrated rod and semis line
- Induction melting and continuous casting form oxygen‑free copper rods with automated take‑up.
- Servo traction, level tracking, and quick‑change crystallizers boost uptime and quality.
- Tension control and double‑head coilers deliver consistent coil builds for downstream use.
- Bulk handling—conveyors, elevators, feeders—links casting, finishing, and dispatch seamlessly.
