Lynas Rare Earths – No Separate Dy/Tb Output8 Apr 2025 13:40
Lynas Rare Earths – Dysprosium and Terbium Production (2023–2024)
No Separate Dy/Tb Output in FY2023: Lynas Rare Earths did not produce any separated dysprosium or terbium in 2023. In the fiscal year ending June 30, 2023, Lynas’s total rare earth oxide output was ~16,780 tonnes (including ~6,142 t of NdPr oxide), but dysprosium and terbium production was 0 t – these heavy REEs were not separated or sold as individual oxides. At that time, “there [was] currently no commercial production” of Dy or Tb outside of China, and Lynas’s heavy rare earth content remained locked in an unseparated concentrate rather than as standalone products. FY2024 Status: Likewise, no standalone Dy or Tb volume was reported for FY2024. Lynas’s output in 2024 was still focused on light REOs (e.g. NdPr, lanthanum, cerium), with no dysprosium or terbium oxides produced. In other words, Lynas’s annual Dy and Tb production in 2023–2024 was effectively zero (no metric tonnage of separated Dy or Tb). Upcoming Production (Mid-2025 Onwards): Lynas has announced plans to begin producing separated dysprosium and terbium by mid-2025. A new solvent extraction circuit at the Lynas Malaysia plant is being configured to process about 1,500 t per year of mixed heavy rare-earth feed (SEGH – samarium, europium, gadolinium, holmium, plus Dy/Tb) and extract dysprosium and terbium oxides. Once this project is operational, Lynas’s product range will for the first time include Dy and Tb oxides. Until then, the most recent confirmed annual production volumes of Dy and Tb by Lynas remain nil (no separate production as of 2023/24). Sources: Lynas’s FY2023 results and industry reports confirm the absence of Dy/Tb output and detail the planned heavy REE separation project. These official statements and reports serve as the basis for the above figures and timelines.
