As governments scramble to safe provides of uncommon earth components, new engineering analysis in Malaysia sheds new mild on why China continues to dominate probably the most essential elements of the provision chain: processing.
The analysis focuses on what many business individuals already contemplate probably the most tough step in uncommon earth manufacturing: separating neodymium and praseodymium to the ultra-high purity ranges wanted for everlasting magnets.
Uncommon earth components are inclined to happen in clusters and behave in a lot the identical approach on a chemical stage. Neodymium and praseodymium are two of an important components in high-performance magnets and are positioned subsequent to one another on the periodic desk.
This proximity makes it very tough to separate them cleanly. Even for viable ores, the separation step is extremely advanced and capital-intensive, so international locations like China that already function such programs at scale proceed to have a bonus.
Analysis exhibits that this step is additional sophisticated by the massive variety of iterations required to separate neodymium from praseodymium to magnet-grade purity.
Their modeled plant design requires roughly 62 equilibration phases, in comparison with solely 16 phases for earlier bulk separations. In sensible phrases, which means amenities able to manufacturing magnet-grade supplies have to be massive, costly, and technologically superior.
loosen your grip
China’s benefit derives primarily from its means to fulfill this requirement on an industrial scale. The nation accounts for about 60 % of the world’s uncommon earth mining, however processes practically 90 % of the world’s provide.
That dominance did not occur by probability. After buying preliminary separation know-how from France within the Eighties, China spent a long time refining solvent extraction strategies, coaching engineers and scaling vegetation far past what most international locations had been keen or allowed to construct.
At present, China produces roughly 70,000 tons of refined uncommon earths yearly. It additionally controls nearly all processing of heavy uncommon earth components. Heavy uncommon earth components are harder to separate and are essential for top temperature and protection functions.
The Malaysian examine subsequently helps why the advantages persist. This exhibits that processing is an actual barrier to entry, even when geology is favorable.
This actuality provides to the issues of america and its allies, particularly as China has demonstrated its willingness to make use of uncommon earths as a geopolitical software.
In 2010, the Chinese language authorities restricted exports to Japan throughout a diplomatic dispute. In 2023, it imposed world restrictions on exports of uncommon earth processing and separation know-how, making it tough for rivals to construct midstream capability.
These developments have created a way of urgency in Washington. Uncommon earths are important to fashionable protection programs, from fighter jets and submarines to precision-guided weapons, and even electrical automobiles and shopper electronics.
Regardless of being the world’s second-largest producer of uncommon earths, traditionally a lot of the materials mined domestically was despatched to China for separation. Till just lately, the nation lacked commercial-scale amenities that would course of ore into completed magnetic supplies.
It is a actuality that the remainder of the world is slowly making an attempt to vary. Since 2020, the U.S. Division of Protection has poured a whole bunch of tens of millions of {dollars} into rebuilding the “mine-to-magnet” provide chain, with tasks largely concentrated in Texas.
These embody mild and heavy uncommon earth separation vegetation, metallic and alloy manufacturing, and everlasting magnet manufacturing.
Nonetheless, its short-term manufacturing capability stays small in comparison with China. New amenities will take years to return on-line, and most will initially concentrate on mild uncommon earths somewhat than heavy components, the place China’s dominance is sort of absolute.
From Undertaking Vault to Africa: US accelerates uncommon earth provide chain technique
America is stepping up efforts to diversify uncommon earth provides past China, supporting early-stage tasks aimed toward rising manufacturing and processing capability outdoors China.
One such transfer occurred in February when america Commerce and Growth Company (USTDA) confirmed its intention to assist Altona Uncommon Earths (LSE:REE)’s Monte Muambe Uncommon Earths mission in Mozambique.
The announcement was made by Thomas Hardy, USTDA Deputy Director and Chief Working Officer, throughout a high-level discussion board on U.S. assist for vital mining tasks in sub-Saharan Africa attended by Altona executives.
USTDA’s assist is predicted to assist outline the technological and monetary growth path for Monte Muambe, which hosts uncommon earth components utilized in everlasting magnets, protection programs, and vitality transition applied sciences. This assist will proceed topic to the conclusion of a proper grant settlement.
This dedication is in keeping with broader U.S. efforts to restructure crucial mineral provide chains, together with current bulletins associated to Undertaking Vault, Washington’s effort to safe strategic reserves and scale back dependence on Chinese language-led processing and refining. This additionally coincides with the launch of the Discussion board for Useful resource Geography and Strategic Engagement (FORGE), introduced on the 2026 Important Minerals Ministers Assembly as a platform to mobilize capital and diplomatic assist for resilient mineral provide networks.
Though Monte Muambe remains to be in its early phases, Altona can also be awaiting assay outcomes from current fluorite and gallium drilling, which the corporate believes may additional improve the strategic attractiveness of the mission. Fluorite is a significant industrial mineral used within the metal, chemical and battery provide chains, by which China additionally holds a big market share.
Taken collectively, U.S. assist for Monte Muambe highlights how governments are more and more leveraging coverage instruments, monetary assist, and strategic partnerships to counter China’s continued dominance in uncommon earth processing, a actuality additionally highlighted in a current Malaysian report.
