New rare earth deposits found in Northeast China could lower mining costs
L'essentiel
- Chinese scientists discovered new rare earth deposits in Heilongjiang and Jilin.
- Unlike southern clay-rich areas, these northern formations are loose sand and gravel, potentially making extraction cheaper, more efficient, and environmentally friendly, bolstering China's global dominance.

Pourquoi c'est important
Chinese scientists have identified a new type of rare earths formation in Heilongjiang and Jilin provinces. These northern formations differ from the clay-heavy deposits in southern China, which require chemical leaching. The new deposits consist of loose sand and gravel formed by natural freeze-thaw cycles.
Chinese scientists have identified a new type of rare earths formation in the nation’s frigid northeastern provinces of Heilongjiang and Jilin – a discovery that could challenge assumptions about how rare earths occur across the country.
Unlike the clay-heavy deposits of southern China – which require chemical leaching to release the elements – the northern formations consist of loose sand and gravel formed by natural freeze-thaw cycles. This difference could make extraction more efficient, less costly and better for the environment.
The find could help China further secure its global dominance in rare earths production, just as Western countries – including the US – scramble to secure supply chains for the critical elements.
The discovery of the new deposits “could potentially rewrite the ‘heavy in the south, light in the north’ pattern of rare earth resources in China”, a team from the Chinese Academy of Sciences’ (CAS) Institute of Geology and Geophysics and the Heilongjiang Bureau of Geology and Mineral Resources said in a paper published in the Chinese journal Acta Petrologica Sinica last month.
Rare earth elements are a group of 17 critical minerals – including cerium, neodymium and dysprosium – that are used to produce electronics, large magnets, superconductors, and green and defence technologies.
