Workforce
In 2020, the Malaysian facility had a 675-strong workforce, with local employees representing 97%.
Overview
The Lynas Malaysia advanced materials plant is the world's largest single rare earths processing facility. It is located on a 100-hectare site in the Gebeng Industrial Estate near Kuantan. The plant processes concentrate from the Mt Weld mine in Western Australia and Mixed Rare Earth Carbonate (MREC) from the Kalgoorlie facility to produce high-quality separated rare earth materials for customers in Asia, Europe, and the United States. The Malaysian operating licence was renewed in March 2026 for a period of ten years, with a condition to cease generating radioactive waste within five years.
Production
Production overview - 2025: rare earth elements 10970 t.
Processing
The facility comprises three main processing areas: cracking and leaching, solvent extraction, and product finishing. In the cracking and leaching stage, Mt Weld concentrate is mixed with sulphuric acid and heated to convert rare earth phosphates to sulphates. Solvent extraction is then used to separate the rare earths into groups and individual elements. In the final product finishing stage, the elements are precipitated as solid carbonates or oxalates, with some being calcined to create oxides. The plant produces a range of products including NdPr oxide, Ce carbonate, Ce oxide, LaCe carbonate, LaCe oxide, and a mixed Heavy Rare Earths compound known as SEG.
Expansion
Lynas is undertaking a significant expansion of its Malaysian operations as part of its 'Towards 2030' growth strategy. The company announced a RM500 million investment to expand its refinery. A new heavy rare earth (HRE) separation facility is being built with a planned capacity to process up to 5,000 tonnes per annum of HRE feedstock. This expansion is establishing Lynas as the only commercial producer of separated heavy rare earths outside of China. The facility began producing separated dysprosium and terbium in 2025. The first production of samarium oxide was achieved in March 2026, ahead of the initial April 2026 schedule. The company plans to progressively add to its HRE processing capacity, with an initial suite of separated products including samarium, gadolinium, dysprosium, terbium, yttrium, and lutetium expected to be available within two years.

Overview
The Mt Weld mine is a high-grade, long-life rare earths deposit located 35km south of Laverton, Western Australia. It is acknowledged as one of the world's premier rare earths deposits. The deposit is situated in a two-billion-year-old volcanic plug. Ore mined is processed at an on-site concentration plant. The resulting rare earths concentrate is then transported to Lynas' processing facility in Kalgoorlie for initial processing or shipped to the Lynas Malaysia refinery for further processing into finished rare earth products.
Production
Production overview - 2022: rare earth elements 15970 t; 2021: rare earth elements 15761 t.
Processing
Ore from the open pit mine undergoes crushing, grinding, flotation, and filtration at the on-site concentration plant to produce a mixed rare earths concentrate. This concentrate is then sent for further processing at facilities in Kalgoorlie, Western Australia, and Kuantan, Malaysia. As part of the expansion, a new capability to process apatite-rich ores is being developed.
Equipment
on-site concentration plant, crushing, grinding, flotation, filtration
Expansion
Approximately US$500 million project to expand capacity at the Mt Weld mine and concentration plant to meet accelerating market demand, with a total cost of $570 million. The expansion targets a feedstock production capacity of 12,000 tonnes per annum of NdPr equivalent. Stage 1, a new concentrate dewatering circuit, transitioned to operations in late 2024. A new capability to process apatite-rich ores is being developed.

Workforce
The project is expected to employ almost 1,100 people during steady-state operations.
Overview
The Kasiya Rutile-Graphite Project, located in Malawi's Central Region, is being developed by Sovereign Metals Limited and the Government of Malawi. It is in the Definitive Feasibility Study phase and is planned as a large-scale, open-pit, dry mining operation with an initial mine life of 25 years. It is the world's largest known natural rutile deposit and the second-largest flake graphite deposit, with potential for heavy rare earth elements recovery.
Production
At steady state, the project is expected to produce approximately 222,000 to 246,000 tonnes of rutile and 265,000 to 288,000 tonnes of graphite annually.
Processing
The processing uses a conventional physical separation flowsheet. Ore is slurried and pumped to a Wet Concentration Plant to produce a Heavy Mineral Concentrate. This concentrate then goes to a Mineral Separation Plant where electrostatic and magnetic separation yield premium-quality rutile. A graphite-rich concentrate is collected from gravity spirals and processed in a separate graphite flotation plant.
Equipment
The planned mining fleet includes draglines, large excavators, mine trucks, front-end loaders, dozers, and graders.
Expansion
The operation is planned in two stages. The first stage will process 12 million tonnes of ore per year, expanding to 24 million tonnes per year in the second stage, which is planned to commence by the end of year five.

Rare Earth Elements
Overview
The Deep Leads project is located approximately 40 to 50 kilometres west of Launceston in a commercial pine plantation. It is a significant ionic adsorption clay (IAC) rare earths project, a type of deposit that is rare outside of China and can be processed with lower costs. In late 2022, a maiden JORC resource of 3.94 million tonnes averaging 918ppm TREO (total rare earth oxide) was declared. More recent announcements state a JORC-compliant mineral resource of 89 million tonnes across the Deep Leads, Rubble Mound and Wind Break deposits. The project is noted for its high concentration of valuable heavy rare earths dysprosium (Dy) and terbium (Tb).
Production
The company's strategy is to commence commercial production of a mixed rare earth carbonate (MREC) as soon as possible.
Processing
The ionic adsorption clay allows for a low-cost, three-step leaching method using ammonium sulphate. Tests conducted by the Australian Nuclear Science and Technology Organisation (ANSTO) have shown high extraction rates, exceeding 80 per cent. ABx Group has successfully produced a mixed rare earth carbonate (MREC) sample, which is the standard tradable product. This MREC has been validated as high-quality and suitable for commercial processing by the US-based company Rare Earth Technologies Inc. (RETi). ABx and RETi are now in discussions regarding a potential commercial supply agreement.
Expansion
As of March 2026, ABx Group announced the discovery of new areas of high-extraction ionic adsorption clay, which has prompted the move to the project development stage.
