China Southern Rare Earth Group Company Limited controls the Ganzhou, Jiangxi Province operations that supply the majority of the world’s heavy rare earths — including dysprosium and terbium, the elements most critical to high-performance NdFeB magnets. A wholly-owned subsidiary of China Rare Earth Group Co., Ltd., China Southern Rare Earth sits at the centre of Beijing’s consolidated rare earth supply strategy and operates across the full value chain from raw ore extraction to refined metal production.
Company Overview
China Southern Rare Earth Group was incorporated in 2015 and is headquartered in Ganzhou, Jiangxi Province — China’s heavy rare earth heartland. Registered capital stands at CN¥752.85 million. The company is wholly owned by China Rare Earth Group Co., Ltd., the national rare earth champion established by Beijing in 2021 through the merger of assets from China Minmetals, Aluminum Corp of China, Ganzhou Rare Earth Group, China Iron & Steel Research Institute Group, and China GRINM Group Corp.
Operations span the complete rare earth value chain: raw ore mining, smelting and separation, comprehensive recycling, intensive processing, research and development, and technical services. The company is unlisted — it does not trade on any public exchange and does not publish financial statements independently of its state-owned parent.
China Southern Rare Earth — Heavy Rare Earth Operations
Jiangxi Province hosts the world’s most significant ion-adsorption clay deposits — the only commercially viable source of heavy rare earth elements at scale. Unlike the hard-rock bastnäsite deposits mined in northern China and at sites such as Mountain Pass in California, ion-adsorption clays yield a disproportionately high share of heavy rare earths: dysprosium, terbium, holmium, erbium, and europium among them.
China Southern Rare Earth’s Jiangxi operations give it effective control over a substantial share of global heavy rare earth supply. Precise production volumes are not publicly disclosed — figures cited in industry sources are estimates based on provincial quota allocations issued by China’s Ministry of Industry and Information Technology (MIIT). According to USGS Mineral Resources data, China accounts for approximately 90% of global heavy rare earth supply, with Jiangxi Province the dominant producing region within that total.
The strategic consequence is direct: every tonne of dysprosium or terbium consumed by Western magnet manufacturers outside China either flows through Chinese separation and export channels or must be sourced from the limited number of non-Chinese projects — most of which remain in development or operate at sub-commercial scale.
Role Within China Rare Earth Group
China Rare Earth Group was formed in December 2021 under direct instruction from the State Council as part of Beijing’s strategy to consolidate the fragmented rare earth sector into three nationally controlled groups — alongside China Minmetals Rare Earth and China Northern Rare Earth Group. The consolidation was designed to improve pricing discipline, enforce production quotas, and strengthen state oversight of a commodity China considers strategically non-negotiable.
China Southern Rare Earth functions as the primary operating entity for the group’s southern and heavy rare earth assets. Sibling entities within the group cover processing, trading, and R&D functions, coordinated at the group level under state direction. The structure means China Southern’s production decisions — including responses to quota changes, environmental enforcement actions, and export licensing — are ultimately made within a policy framework set by Beijing rather than by commercial logic alone. For a detailed analysis of how this consolidation shapes Western supply chain risk, see China Rare Earth Export Controls 2026: Project Vault & the Minerals Cold War.
Strategic Importance to Western Manufacturers
Western manufacturers of EV motors, direct-drive wind turbines, and military guidance systems depend on heavy rare earth oxides and metals that China Southern Rare Earth’s operations produce. A single EV traction motor requires approximately 1–2 kg of NdFeB magnet material; dysprosium and terbium are added to that alloy to maintain coercivity — resistance to demagnetisation — at the elevated temperatures inside an operating motor.
Export controls introduced by Beijing since 2023 on heavy rare earth processing technology, and subsequently on certain heavy rare earth compounds, have progressively tightened Western buyers’ room to manoeuvre. Japanese magnet producers — including Shin-Etsu Chemical and TDK — maintain the most sophisticated long-term supply agreements and recycling loops outside China, but European and North American OEMs remain heavily exposed to spot and contract markets that ultimately price off Chinese output. The extent of that exposure is mapped in detail in Rare Earth Magnets: Western Supply Build-Out Reshapes Pricing.
No Western heavy rare earth project currently operates at a scale sufficient to displace more than a marginal share of Chinese supply. Projects in Canada, Australia, and Greenland are advancing, but realistic timelines to commercial-scale heavy rare earth separation remain measured in years, not months.
Environmental and Regulatory Context
Ion-adsorption clay mining in Jiangxi has a documented history of environmental damage — in-situ leaching with ammonium sulphate solution has caused groundwater contamination and soil degradation in producing counties. Chinese regulators have tightened enforcement since the mid-2010s, requiring remediation bonds, stricter leaching agent controls, and reclamation obligations. The shift to ammonium sulphate-free leaching methods is ongoing but uneven across Jiangxi’s production base.
For Western procurement teams and investors, the environmental profile of Jiangxi heavy rare earths creates a due diligence challenge: supply chain traceability from ion-adsorption clay to finished magnet is difficult to establish, and third-party audit coverage of Chinese mine sites is limited. The ESG implications — and how Western buyers are responding — are examined in Rare Earth ESG Standards 2026: Navigating the New Era of Responsible Mining.

What to Watch
The key variables for buyers and analysts monitoring China Southern Rare Earth Group are the MIIT’s semi-annual production quota announcements — which set the ceiling on legal heavy rare earth output from Jiangxi — and the pace of Beijing’s export licensing decisions on heavy rare earth compounds and alloys. Jiangxi provincial environmental enforcement actions can affect mine-level output in the short term; historically, tightening inspections have correlated with price spikes in dysprosium and terbium on the Shanghai Metals Market. The strategic direction of China Rare Earth Group at the parent level will also determine how aggressively China Southern Rare Earth pursues downstream processing and value-added product lines versus raw and intermediate material exports.

What does China Southern Rare Earth Group produce?
China Southern Rare Earth Group produces medium and heavy rare earth oxides, metals, and alloys — principally dysprosium, terbium, holmium, and related elements extracted from ion-adsorption clay deposits in Jiangxi Province. Operations cover the full value chain from raw ore mining through smelting, separation, and intensive processing.
Who owns China Southern Rare Earth Group?
China Southern Rare Earth Group is a wholly-owned subsidiary of China Rare Earth Group Co., Ltd., which is itself a state-owned enterprise established in 2021 under the direction of China’s State Council. It is not publicly listed on any stock exchange.
Where does China Southern Rare Earth operate?
Operations are concentrated in Ganzhou, Jiangxi Province — the principal region for ion-adsorption clay rare earth mining in China and the world’s dominant source of heavy rare earth elements including dysprosium and terbium.
Why are China Southern’s heavy rare earths strategically important?
China Southern Rare Earth controls a significant share of global supply of dysprosium and terbium — elements essential for maintaining the performance of NdFeB permanent magnets at operating temperatures in EV motors, wind turbine generators, and defence systems. No non-Chinese project currently produces these elements at comparable scale.
What is China Southern Rare Earth’s connection to China Rare Earth Group?
China Southern Rare Earth Group is the primary operating subsidiary through which China Rare Earth Group Co., Ltd. manages its southern China and heavy rare earth assets. China Rare Earth Group was formed in 2021 as part of Beijing’s consolidation of the national rare earth sector into three state-controlled entities, with China Southern Rare Earth serving as the heavy rare earth production arm within that structure.
