The pilot plant has been set up in Chennai, Tamil Nadu, India. Bridge Green Upcycle Pvt. Ltd. is headquartered at 120 Hawley St, Binghamton, NY 13901, USA.





Black Mass Processing Hydrometallurgical Plant for Lithium-Ion Battery Recycling: Project Summary
The project involved the delivery of a fully integrated pilot scale Black Mass Processing Hydrometallurgical Plant for Lithium-Ion Battery Recycling to test and optimize the recovery of metals from lithium-ion battery black mass.
Project Scope
- Process design and engineering
- Equipment design and fabrication Module assembly
- Integration of process instrumentation and control
- Mechanical and electrical installation
- plant commissioning
- Performance validation
This Black Mass Processing Hydrometallurgical Plant for Lithium-Ion Battery Recycling provides an opportunity for controlled testing of the hydrometallurgical recovery processes prior to scaling to commercial production and provides flexibility for research, process optimization and validation of new technology.
What is the Black Mass?
Black mass is the fine powder generated by dismantling and shredding end-of-life lithium-ion batteries. It contains precious metals such as:
- Lithium
- Nickel
- Cobalt
- Manganese
- Graphite
- Copper
The recovery of these materials through advanced hydrometallurgical processes greatly reduces the environmental impact while supporting the growing demand for critical battery materials.
Why Hydrometallurgical Processing?
Hydrometallurgy has a number of advantages over conventional methods of recovery:
- Improved recovery efficiency for valuable metals
- Reduced energy consumption
- Higher process selectivity
- Scalable and environmentally friendly operation
- Lower operating temperatures than pyrometallurgical processes
Pilot plants are of great importance in the validation of these processes prior to their industrial implementation.
Engineering the Pilot Plant
The construction of a pilot scale hydrometallurgical facility requires a combination of process engineering and practical manufacturing experience.
Our engineering team designed a Black Mass Processing Hydrometallurgical Plant for Lithium-Ion Battery Recycling plant that can support multiple stages of metal recovery and also allows operational flexibility.
Key engineering considerations were:
- Design of Modular Processes
- Selection of corrosion resistant equipment
- Safe handling of chemicals
- Automation of processes
- Easy to maintain
- Flexibility in the operation of different process parameters
- Dependable instruments and monitoring systems
The result is a compact pilot plant for research, optimization and demonstration purposes.
