Producer
China Northern Rare Earth Group
China's largest rare earth company by production volume; controls the Bayan Obo mining complex in Inner Mongolia — the world's largest rare earth deposit (light rare earths, primarily bastnäsite/monazite). Listed on Shanghai Stock Exchange. Subsidiary of Baotou Steel Group (itself a subsidiary of China Baowu, the world's largest steel company). Bayan Obo was initially developed as an iron ore deposit; rare earths were a 'byproduct' discovery that became the dominant geopolitical asset. China Northern's production plus other Chinese producers gives China ~60% of global ore production and ~85% of separated NdPr oxide.

Bayan Obo Rare Earth & Iron Ore Mine (Inner Mongolia) →
CNInner Mongolia · mine
World's largest rare earth deposit (40%+ of known global reserves; ~50% of global annual production); simultaneously one of China's major iron ore mines. Ore body: cerium 50% of REE content, lanthanum 30%. Annual tailings exceed 3.5 million metric tons. Located 150 km north of Baotou, Inner Mongolia. A single geological formation in one Chinese city supplies ~50% of all rare earth elements — including most of the world's lanthanum.

CNInner Mongolia · mining
World's largest rare earth deposit; co-mined by Baotou Steel Group for iron ore; rare earth (including cerium) is essentially a byproduct of iron mining. Produces ~60% of China's rare earth output and ~35% of global rare earth supply including cerium for glass polishing.

China Northern — Bayan Obo Mining Complex, Inner Mongolia →
CNBayan Obo, Baotou, Inner Mongolia · mine
World's largest rare earth deposit by ore reserves; discovered 1927 by geologist Ding Daoheng; developed as iron ore mine (for Baotou Steel) from 1957; rare earths were initially a 'byproduct.' The Bayan Obo deposit contains ~1 billion tonnes of iron ore AND the world's most concentrated light rare earth reserves (bastnasite/monazite intergrown with iron ore). The geopolitical significance of rare earth dominance was not recognized until the 1970s-1980s. Processing facility in Baotou (~130km away) extracts and separates NdPr oxide. China Northern is a subsidiary of Baotou Steel, which is owned by China Baowu (world's largest steel company).

Did you know2025
China Northern Rare Earth's single Bayan Obo mine provides feedstock for at least four structurally separate industrial supply chains simultaneously: (1) NdPr oxide for NdFeB permanent magnets — the core input for EV drive motors, direct-drive wind turbines, and defense guidance systems; (2) lanthanum oxide for FCC catalysts — used in every petroleum refinery globally for gasoline cracking; (3) cerium oxide for glass polishing — used in CMP semiconductor wafer polishing and automotive glass manufacturing; (4) lanthanum/mischmetal for NiMH battery anodes — still used in Toyota and Honda hybrid vehicles and industrial batteries. A rare earth export control targeting Bayan Obo's output simultaneously disrupts clean energy transition (EV/wind), petroleum refining, semiconductor manufacturing, and hybrid vehicle production. The April 2025 Chinese export controls on NdPr and 6 other rare earths demonstrated this multi-sector cascade in real time.
Reuters ↗Origin2023
The Bayan Obo mine — the source of roughly 40% of global rare earth production — was initially discovered and developed as an IRON ORE deposit, not a rare earth mine. Chinese geologist Ding Daoheng first mapped the deposit in 1927 as a potential iron ore source; Baotou Steel began commercial iron ore extraction in the 1950s. Rare earth minerals (bastnaesite, monazite) were present in the iron ore body but treated as waste rock for decades. It was not until the 1970s-1980s, as rare earth applications for magnets, phosphors, and catalysts grew, that the rare earth co-product was systematically separated rather than discarded. The world's most strategically critical rare earth deposit is technically a 'byproduct' mine — rare earths became the dominant asset of what is formally a steel company subsidiary. China Northern's parent is Baotou Steel Group, a subsidiary of China Baowu, the world's largest steel producer by volume.

China Northern Rare Earth's Bayan Obo reserve dominance — combined with China's 6 licensed rare earth mining groups collectively controlling ~60% of global mine output and ~85% of global separated rare earth production — creates an asymmetric supply chokepoint with no near-term Western substitute. Bayan Obo estimated proven reserves: ~800 million metric tons rare earth ore (REO equivalent: ~43 million MT). Second-largest deposit: Mountain Pass (California, MP Materials): ~1.5 million MT REO proven reserves — roughly 3% the size of Bayan Obo. The only viable near-term Western supply chain is Mountain Pass (mining) + NioCorp (Nebraska, not yet producing) + Australian producers (Lynas/Northern Minerals) — collectively a fraction of Chinese capacity. USGS estimates 10-15 years to build alternative processing infrastructure at scale. The April 2025 export controls validated that China holds the supply chokepoint and is willing to deploy it geopolitically.
