- China Northern Rare Earth Group leads the world’s lanthanum producers, processing the Bayan Obo deposit’s bastnäsite-monazite ore into separated light rare earth oxides.
- Ranking basis: current production volume, resource scale, and market position, not aspirational capacity.
- MP Materials is the largest non-Chinese producer, with more than 80% of Mountain Pass output made up of lanthanum and cerium.
- Two major projects on this list, Iluka’s Eneabba refinery and Shenghe’s Ngualla acquisition, are pre-production and flagged accordingly.
- China’s northern and southern axes together account for the overwhelming majority of global supply.
Lanthanum is a light rare earth element produced almost entirely as a co-product of bastnäsite and monazite mining, alongside cerium, neodymium, and praseodymium. Global lanthanum producers are concentrated in a small number of integrated mine-to-oxide operations: China accounted for approximately 270,000 metric tons of total rare earth oxide (REO) production in the most recently confirmed USGS Rare Earths Statistics, against 51,000 tons from the United States and 29,000 tons from Australia. This list ranks the ten companies and projects that matter most to lanthanum supply in 2026, from established Chinese state producers to Western and emerging-market projects still working toward first production. For background on the element itself, see our what is lanthanum guide.
How We Ranked the Top 10 Lanthanum Producers
This ranking of lanthanum producers weighs three factors: confirmed current production volume, resource size and grade, and market position within the light rare earth supply chain. Where a project has not reached commercial production, it is included only if its resource scale or strategic significance makes it materially relevant to future lanthanum supply, and its status is stated plainly rather than implied.
1. China Northern Rare Earth Group, China (SHA: 600111)
China Northern Rare Earth is the world’s largest lanthanum producer by volume, converting concentrates from the Bayan Obo deposit in Inner Mongolia into separated light rare earth oxides. Bayan Obo is the single largest rare earth resource on Earth, holding more than 40% of known global REO reserves, and its mineralogy runs overwhelmingly to neodymium, praseodymium, lanthanum, and cerium. China Northern does not mine the deposit itself; it processes concentrate supplied under long-term agreement from Baotou Steel Union. Its scale, combined with China’s biannual mining quota system, makes it the single largest variable in global light rare earth pricing. See our full profile: China Northern Rare Earth.
2. MP Materials, United States (NYSE: MP)
MP Materials is the largest lanthanum producer outside China, operating the only active rare earth mine and processing facility in the United States at Mountain Pass, California. The site’s bastnäsite ore is heavily weighted toward light rare earths, with lanthanum and cerium together accounting for more than 80% of output, against roughly 15% neodymium-praseodymium. MP produced a record 50,692 metric tons of total REO in FY2025, up 12% year on year, and posted record Q1 2026 NdPr output of 917 metric tons. See our full profile: MP Materials.
3. Lynas Rare Earths, Australia (ASX: LYC)
Lynas Rare Earths is the largest non-Chinese, fully integrated lanthanum producer with separation capability, mining Mt Weld in Western Australia and processing concentrate at its Kuantan facility in Malaysia. Its product range spans both light rare earths, including lanthanum and cerium, and a growing heavy rare earth slate following 2025’s commercial dysprosium and terbium separation milestones. Lynas reported Q4 FY26 revenue growth and continued NdPr ramp-up in results released 21 July 2026. See our full profile: Lynas Rare Earths.
4. Baotou Steel Union, China (SHA: 600010)
Baotou Steel Union is the mining entity behind China’s lanthanum dominance, extracting the Bayan Obo ore body and supplying concentrate to China Northern Rare Earth for separation. It does not itself process concentrate into separated oxides, but as the upstream operator of the world’s largest rare earth deposit, its production quota allocation is closely watched as a leading indicator for light rare earth supply and pricing. See our full profile: Baotou Steel Rare Earth.
5. China Rare Earth Group, China
China Rare Earth Group is the state consolidator of China’s southern ionic clay axis, controlling China Southern Rare Earth Group, Guangdong Rare Earth Industry Group, and Rising Nonferrous Metals across Jiangxi, Guangdong, and Fujian provinces. These deposits are the world’s primary source of heavy and medium rare earths, but their aggregate volume is large enough that China’s southern lanthanum producers still contribute meaningfully to total supply, even though lanthanum is a smaller share of output there than in the north. See our full profile: China Rare Earth Group.
6. Guangdong Rare Earth Industry Group, China
Guangdong Rare Earth Industry Group operates ionic clay deposits in Guangdong province under China Rare Earth Group’s consolidated ownership. Ion-adsorption clays are naturally depleted of cerium and much of their lanthanum relative to bastnäsite ore, so Guangdong is a comparatively minor lanthanum producer set against its dominant position in dysprosium and terbium. It is included here for aggregate volume and its role in China’s dual-axis supply structure. See our full profile: Guangdong Rare Earth.
7. Shenghe Resources, China (SSE: 600392)
Shenghe Resources operates less as a primary lanthanum producer and more as the industry’s dominant light rare earth trader and processor, holding equity stakes across Mountain Pass (7.7%), Peak Rare Earths’ Ngualla project, and other international assets. The company is targeting rare earth oxide output capacity above 30,000 tonnes per year and continues expanding its overseas footprint. Its trading reach means Shenghe touches a larger share of global lanthanum flow than its own mining assets suggest. See our full profile: Shenghe Resources.
8. Indian Rare Earths Limited (IREL), India
IREL is India’s sole dedicated lanthanum producer, a state-owned PSU under the Department of Atomic Energy that processes monazite-bearing beach sands at its Kerala, Tamil Nadu, and Odisha plants into high-purity lanthanum carbonate and oxide. India’s confirmed rare earth output remains modest against its reserve base, but IREL’s Aluva refinery and newer mini-plants at Bhopal give it a narrow but genuine production role that larger, resource-rich but pre-production Asian projects do not yet match. See IREL (India) Limited for further detail.
9. Iluka Resources, Australia (ASX: ILU)
Pre-production. Iluka’s Eneabba refinery in Western Australia is not yet a lanthanum producer, but its scale earns it a place on this list: construction was approximately 60% complete as of Iluka’s most recent quarterly report, with commissioning pushed to mid-2027. Once operational, Eneabba will process monazite stockpiled since the 1990s into separated light and heavy rare earth oxides, including lanthanum, positioning it among a small number of non-Chinese separated rare earth producers. See our full profile: Iluka Resources.
10. Ngualla Rare Earth Project, Tanzania (Shenghe Resources)
Pre-production. Ngualla is one of the world’s largest undeveloped NdPr-lanthanum-cerium deposits, with 887,000 tonnes of contained rare earth oxides at 4.8% grade. Shenghe Resources completed its full acquisition of former owner Peak Rare Earths in September 2025, and commissioning is now targeted for approximately Q3 2027. The project is not yet a lanthanum producer, but its resource scale and Chinese ownership make it strategically significant for future light rare earth supply out of Africa. See our full profile: Peak Rare Earths.
The following table summarises the ten lanthanum producers and near-term projects covered above.
| Company | Country | Status | Key Asset | Notable Detail |
|---|---|---|---|---|
| China Northern Rare Earth Group | China | Producing | Bayan Obo (via Baotou Steel) | World’s largest light REE producer |

| Ngualla (Shenghe) | Tanzania | Pre-production | Ngualla deposit | 887,000t REO; Shenghe-owned since Sep 2025 |
The Outlook for Lanthanum Producers
The lanthanum producers landscape through the rest of 2026 remains dominated by China’s northern axis, but the picture is shifting at the margins. MP Materials and Lynas continue to demonstrate that non-Chinese light rare earth separation is commercially viable at scale, and both Iluka’s Eneabba refinery and Shenghe’s Ngualla acquisition point to a widening base of producers over the next 18 to 24 months, even as neither is generating output yet. As more lanthanum producers reach commercial scale outside China, price benchmarks and supply security assessments will need to account for a less concentrated market than the one that has prevailed for the past decade. For comparison, see our related ranking of top 10 neodymium producers, which overlaps heavily with this list given shared bastnäsite and monazite feedstocks.

Who is the #1 lanthanum producer and why?
China Northern Rare Earth Group leads due to its access to the Bayan Obo deposit, the largest known rare earth resource on Earth and one overwhelmingly weighted toward light rare earths including lanthanum. Its scale and China’s quota system give it structural dominance that no other single producer currently matches.
What criteria determines the lanthanum producers ranking?
The ranking weighs confirmed current production volume, resource size and grade, and market position within the light rare earth supply chain. Pre-production projects are included only where resource scale or strategic significance is material, and their status is stated explicitly rather than implied.
Why does China dominate global lanthanum production?
China’s dominance stems from its control of both major rare earth deposit types: the bastnäsite-monazite ore at Bayan Obo, which is light rare earth-rich, and the ionic clay deposits of southern China, which are heavy rare earth-rich but still contribute lanthanum volume. This structural resource advantage, combined with decades of processing infrastructure investment, underpins China’s position across the full rare earth spectrum.
Why is lanthanum often a byproduct rather than a primary target for producers?
Lanthanum and cerium typically make up the largest share of rare earth ore by volume but carry comparatively low per-kilogram value next to neodymium, praseodymium, dysprosium, and terbium. Most producers optimise their circuits around the higher-value magnet metals, meaning lanthanum output is largely a function of total ore processed rather than a standalone production target.
What would change the lanthanum producers ranking over time?
New mine and refinery construction, particularly outside China, is the primary variable. Facilities like Iluka’s Eneabba refinery and Shenghe’s Ngualla project would materially add to non-Chinese lanthanum supply once commissioned, while Chinese quota policy and export licensing continue to shape the volume and pricing of existing output.
