This phased approach allows for methodical recovery while maintaining production continuity, showcasing modern mining industry evolution in practice.
Major Infrastructure Developments Transform Operations
Africa's Largest Copper Smelter Nears Completion
The most significant infrastructure development at Kamoa-Kakula is the imminent commissioning of what will be Africa's largest copper smelter, scheduled to begin in early November 2025. This direct-to-blister copper smelter represents a pivotal moment in the complex's evolution toward vertical integration.
The smelter will produce blister copper (approximately 99% pure) directly, bypassing the conventional matte smelting step. This technological approach offers several advantages:
- Reduced processing steps compared to conventional smelting
- Lower overall energy consumption
- Decreased environmental footprint
- Significant reduction in transportation costs for concentrate
Once fully operational, the smelter is expected to drive lower overall cash costs for the Kamoa-Kakula operation, strengthening its competitive position among global copper producers. This development comes at a critical time when electrifying copper investments are gaining momentum worldwide.
Power Supply Reinforcements Near Completion
To ensure operational stability during the critical smelter commissioning phase, the installation of a 60 MW uninterruptible power supply (UPS) unit is nearing completion. This substantial power infrastructure upgrade is specifically designed to protect the smelter facility from power interruptions during the initial ramp-up period.
The UPS represents a strategic investment in operational resilience, addressing a common challenge in the region where grid power fluctuations can impact complex metallurgical processes. This protection is particularly crucial during the commissioning phase of the smelter when systems are most vulnerable to disruptions.
Energy infrastructure specialists note that this level of power backup capacity is exceptional for mining operations in the region and reflects the critical importance of maintaining continuous operations at the smelter during startup.
