Lynas to produce heavy rare earths in Malaysia by 2025

Australia-listed mining company Lynas Rare Earths plans to start producing two separated heavy rare earth (HRE) products at its Malaysian facility by 2025.

Lynas will start production of separated dysprosium and terbium at one of Lynas Malaysia's solvent extraction circuits in 2025. The facility is designed to separate up to 1,500 t/yr of a mixed heavy rare earth compound containing mixed samarium, europium, gadolinium, holmium, dysprosium and terbium (SEGH).

The HRE project has completed initial engineering and detailed engineering design is underway, with commissioning and ramp-up expected in mid-2025. Lynas' HRE product range will increase to five products — dysprosium, terbium, unseparated samarium/europium/gadolinium, holmium concentrate and unseparated SEGH — after the separation of dysprosium and terbium from the SEGH compound.

Dysprosium and terbium are needed to produce high-performance rare earth magnets, which are used in consumer electronics, electric vehicle engines and other automotive applications.

Lynas is also progressing pre-construction activities for its planned rare earth processing facility in the US. Its facilities in Malaysia and the US have been designed to accept third-party feedstocks once they start operations.

The heavy rare earths production provides a pathway to accelerate Lynas' commitment to processing all of the elements at the firm's Australian Mount Weld ore site, said Lynas' chief executive officer and managing director, Amanda Lacaze.

Supply chains

More national governments have been taking action to build or diversify more resilient and sustainable rare earth supply chains, to keep up with a fast-evolving clean energy transition and reduce their heavy reliance on China-origin supplies. China is the largest supplier of medium and heavy rare earths in the world, and it has been implementing stricter export control policies for rare earth extraction and separation technology.

There is limited progress on the development of rare earth projects outside China, especially in the HRE market, mostly because of exploration technique restrictions, ore resource shortages, production costs and capital pressure and environmental consideration and so on. US-based rare earth producer MP Materials aims to develop a facility to produce HREs in the next few years. It has started neodymium-praseodymium oxide production since the third quarter of last year and targets commercial production of finished magnets by late 2025.

Australian mineral producer Iluka Resources plans to achieve an output capacity of up to 23,000 t/yr of rare earth oxide, including 5,500 t/yr of neodymium-praseodymium oxide and 725 t/yr of dysprosium and terbium oxide from its refinery in Australia.
