DuPont has launched a comprehensive Direct Lithium Extraction (DLE) portfolio aimed at helping lithium producers improve recovery rates, increase process efficiency and accelerate commercial production as global demand for the metal continues to climb.
The new offering brings together more than 20 products spanning lithium-selective sorbents, nanofiltration and reverse osmosis membranes, ion exchange resins and ultrafiltration technologies, providing customers with tailored solutions for a wide range of lithium brine compositions.
The integrated portfolio is designed to support every stage of the lithium brine treatment process—from extraction and purification to final concentration—allowing operators to deploy either complete end-to-end systems or individual technologies based on project requirements.
As the industry looks beyond traditional lithium production methods such as hard rock mining and evaporation ponds, direct lithium extraction is gaining momentum as a faster and more efficient approach to recovering lithium from brine resources.
A key feature of DuPont's portfolio is its flexibility to address varying operating conditions and resource characteristics.
The portfolio includes lithium-selective DuPont AmberSorb adsorbent technologies engineered for both high- and low-temperature brine streams, alongside multiple grades of FilmTec™ LiNE nanofiltration and reverse osmosis membranes incorporating low salt rejection reverse osmosis (LSRRO) technology to achieve ultra-high lithium concentration.
The portfolio also integrates DuPont IntegraTec and Inge ultrafiltration modules, FilmTec membrane technologies and DuPont AmberLite ion exchange resins to enhance lithium yield, purity and concentration throughout the extraction process.
"DLE processes are highly sensitive to the lithium brine composition, temperature, and competing ions. By integrating the lithium-selective sorbents, membranes, and ion exchange technologies into a single process design framework, we can optimize the full flowsheet rather than treating them in isolation," said Martin Deetz, Senior R&D Laureate for DuPont Water Solutions.
"Our customers are trying to move from the lab to reliable lithium production as quickly as possible. By combining these technologies with advanced modeling, testing, and piloting support, we can help accelerate the design of tailored, end-to-end lithium extraction flowsheets for their specific brine resources and goals."
Beyond its product portfolio, DuPont is expanding technical support for lithium developers through its global research and development network.
