Hydrometallurgy Plant Client Background
A European battery recycler, facing mounting pressure to meet the EU’s 2030 target of 70% lithium recovery from lithium-ion batteries, partnered with us deploy a hydrometallurgy plant capable of processing 10,000 tons of black mass annually.
Our Solution: Custom-Built Hydrometallurgy Plant
As specialists in hydrometallurgy plant engineering, we delivered a fully automated, closed-loop system tailored to their black mass composition (NMC 811 and LFP batteries). Key features included:
1. Advanced Leaching Circuit
Targeted Acid Recycling: Reduced sulfuric acid consumption by 40% through AI-driven pH control and real-time monitoring.
Selective Metal Extractio: Achieved 95% lithium recovery and 92% cobalt/nickel purity using multi-stage solvent extraction.
2. Zero-Liquid Discharge (ZLD) System
Recycled 98% of process water and recovered residual electrolytes, eliminating wastewater discharge.
3. Energy Recovery Module
Captured waste heat from exothermic reactions to power auxiliary systems, cutting energy costs by 25%.
4. Scalable Design
Modular architecture allowed future capacity expansion to 20,000 tons/year.

Implementation Timeline
Phase 1 (3 months): Site assessment, black mass feedstock analysis, and plant design.
Phase 2 (6 months): Equipment fabrication and factory acceptance testing (FAT).
Phase 3 (2 months): Onsite installation, staff training, and commissioning.
Results: Transforming Challenges into Profits
1. Boosted Recovery Rates
Lithium recovery surged from 48% to 94%.
Cobalt and nickel purity reached 92%, qualifying for direct sale to cathode manufacturers.
2. Operational Efficiency
Automated reagent dosing slashed chemical costs by 35%.
Plant uptime increased to 95% with predictive maintenance protocols.
