Century Lithium Achieves High Recovery of Rare Earths and Critical Elements from Primary Leach Solutions
words.Century Lithium reported that laboratory tests at its Angel Island lithium project in Nevada can recover more than 97 % of rare‑earth elements (REEs) from primary leach solutions without affecting lithium extraction. The ion‑exchange process selectively captures REEs such as dysprosium, neodymium and scandium, offering a valuable by‑product that could boost the project’s economics and align with U.S. goals for domestic critical‑metal supply. The company will now optimize performance, scale REE processing, explore commercial partnerships, and quantify the economic impact of this dual‑output operation.
