Lynas Rare Earths (ASX:LYC) has announced the first production of terbium oxide at its advanced materials plant in Malaysia. This achievement follows the initial production of dysprosium oxide in May 2024, marking the second separated heavy rare earth oxide produced at the facility. Terbium, primarily used in electronics and as a dopant in metals, enhances low-energy lightbulbs, mercury lamps, and medical x-ray safety.
CEO Amanda Lacaze stated that Lynas can now supply both dysprosium and terbium oxide, essential for rare earth permanent magnets in electric motors. The feedstock originates from Lynas’ Mt Weld deposit in Western Australia, known for both light and heavy rare earth minerals. The production aims to enhance supply chain resilience for manufacturers. Rare earth magnets, alloys of rare earths, outperform ceramic and alnico magnets, boasting a remanence exceeding 1.2 tesla. Lynas’ Kalgoorlie facility will process Mt Weld feedstock, producing up to 68,000 tonnes of mixed rare earth carbonate (MREC). The first MREC shipment occurred in June 2024, destined for further processing in Malaysia. The Australian rare earths pipeline is projected to reach $1.9 billion by 2029-30, with operating facilities contributing $1.3 billion in exports.
