Processing description
Through this method, we can use the copper scrap (copper content ≧96%) to produce 99.95% cathode copper. For low grade copper scrap, this method is not economical.
Processing flow
Copper scrap —- separating —-shredding and cutting —– electrolysis— cathode copper
Copper Scrap Solution Comparison | ||||
Process | Purity | Scrap Quantity | Product/Purity | Main Equipment |
CCR | >95.2% | 10KT-50KT/annually | Rod/99.9% | Furnace, Casting/rolling, fume treatment |
Adding to upcast after refinery | >96% | 1-3KT/annually | Rod/99.9% | Refining furnace, Up casting line |
Adding to upcast without refinery | >99.5% | 5-20KT/annually | Rod/99.95% | Up casting line |
Direct Electrolysis | >96% | <2 KT/a nnually | Cathode/99.95% | Electrolysis system, water purification |
Anode Electrolysis | 90-92% | 5KT-150KT/annually | Cathode/99.97% | Refinery furnace, fume treatment,anode caster, electrolysis system, water purification |
