DuPont provides end-to-end direct lithium extraction (DLE) solutions for lithium extraction from brine, addressing every stage of the flowsheet, from pretreatment and selective extraction to purification, concentration, and final polishing. By integrating advanced sorbents, membranes, and ion exchange resins, we help customers efficiently recover high-purity lithium from complex brine streams.
Our solutions are designed for flexibility and performance across diverse operating conditions. Through tailored system design, testing, and modeling capabilities, we help optimize each flowsheet to improve lithium yield, enable more efficient lithium extraction, and support long-term operational reliability.
Compared to traditional extraction methods, our DLE approach helps enable more sustainable lithium production by supporting improved water management and reducing resource loss throughout the process.
This flowsheet represents a typical direct lithium extraction (DLE) process, illustrating how separation technologies are integrated across each stage, from pretreatment and selective extraction to concentration and final polishing.
We work closely with customers to design and optimize the right DLE flowsheet for their specific brine composition and operating conditions. By combining sorbents, membranes, and ion exchange technologies, we provide solutions across the full process, helping to enable efficient lithium recovery and tailored system performance.
Our portfolio includes technologies designed for each stage of the DLE process, helping to enable efficient lithium recovery across a wide range of brine conditions.
