Direct Lithium Extraction (DLE) & Refining
To access lithium brines in wet climates and improve lithium recovery,Direct lithium extraction (DLE)is gaining popularity. After prefiltration, DLE systems produce a lithium chloride solution of 1,000 mg/L containing impurities, with leading DLE systems achieving lithium to total dissolved solids ratio >0.08.
Saltworks is DLE agnostic and works downstream of DLE, where we use concentrating, refining, and converting (CRC) technology to produce battery-grade lithium carbonate or lithium hydroxide.
Our solutions accept varying DLE eluates and precisely target impurities, concentrate lithium in advanced membrane systems, and selectively precipitate high-quality lithium chemicals.
