As Africa’s mining and recycling sectors expand, demand for advanced metal refining solutions has surged. A South African copper recycler recently faced a critical challenge: upgrading their outdated system to process 2000kg/day of raw copper anode plates into high-purity cathodes efficiently. Here’s how our copper electrolytic refining equipment delivered a transformative solution—and set a new industry benchmark.
The Challenge: Low Efficiency, High Costs, and Substandard Output
The client struggled with:
1. Outdated Technology: Manual sorting and basic electrolytic cells produced cathodes with only 97% purity, far below the global market standard of 99.99%.
2. Energy Inefficiency: High power consumption (4.2 kWh/kg) eroded profit margins.
3. Capacity Limitations: Their legacy system could only process 1200kg/day, creating bottlenecks as raw material inflows increased.
4. Frequent Downtime: Poor corrosion resistance in old tanks led to maintenance delays.
With copper prices soaring, the client needed a reliable copper electrolytic refining plant to maximize yield, reduce costs, and meet international quality standards.
Our Solution: Customized Copper Electrolytic Refining Equipment
We engineered a turnkey system tailored to Africa’s harsh industrial environment, including:
1. Automated Electrolysis Cells
Advanced titanium cathodes and Pb—Ca—Sn alloy anodes improved current efficiency to 92%, up from 78%.
Automated electrolyte circulation reduced manual intervention, ensuring stable 99.99% pure copper cathode production.
2. Energy Recovery Systems
Regenerative braking technology cut energy consumption by 30% .
3. Scalable Processing Capacity
Modular design allowed seamless scaling from 2000kg/day to 5000kg/day as demand grows.
4. Durable Construction
Corrosion-resistant polymer tanks and dust-proof components ensured reliability in Africa’s high-temperature, high-humidity conditions.
5. Real-Time Monitoring
IoT sensors tracked electrolyte composition, temperature, and voltage, enabling predictive maintenance.
Results: Higher Purity, Lower Costs, and Sustainable Growth
Installing the copper electrolytic refining equipment, the client achieved:
99.99% Pure Copper Cathodes: Meeting standards for premium-grade copper.
