Veolia’s Capabilities for lithium, nickel and cobalt producers.


Process Development Expertise Veolia Water Technologies has a long history of supplying systems for purification, recovery, and drying of inorganic chemicals utilizing its HPD® Evaporation and Crystallization Technologies.
State-of-the-art research and development capabilities allow investigation into the behavior of complex multi-component aqueous systems and subsequent optimization of the process design to most efficiently achieve the desired product quality and reduce performance risk. Unlike typical for hire hydrometallurgical laboratories, Veolia also designs and supplies commercial equipment. Veolia understands how learnings at the lab or pilot scale translate to commercial performance and will take responsibility for the processes that are developed in our facility. We can typically scale up from the laboratory scale directly to offer commercial systems on a design build basis with complete process, mechanical, and schedule guarantees.
Precursor materials for lithium ion battery production must be provided at extremely high purity levels. Nickel and cobalt compounds are particularly sensitive to contamination during the crystallization process. Through our crystallization expertise supplemented with specific testing, Veolia is able to identify the appropriate crystallization processes required to achieve desired purity levels from unique sources with differing contaminant levels.

Research & Development
Veolia’s 5,000 m2 Research and Development Center is crucial for development of challenging process designs for HPD® Evaporation and Crystallization technologies.
The facility is home to a wide variety of tools used for investigation of new process designs, testing to support customer projects, and development of new technologies. It is the foundation for design evaluation, feasibility, and process validation as well as improvement and economizing overall system designs.
The analytical, bench-scale, and pilot-scale testing capabilities, with an extensive catalog of data, allows advancement of first-of-a-kind innovations.
This is especially important to design processes for achieving the purity requirements in evolving lithium, nickel and cobalt applications and purity requirements.
Rigorous testing provides the confidence that the commercial system will perform as designed.
