For years, the global rare-earth race was treated mainly as a mining problem.
Countries searched for deposits. Companies developed projects. Governments looked for ways to increase domestic production.
That approach is changing.
The more important contest is moving downstream, where rare-earth materials are separated, refined, converted into metals and alloys, and manufactured into permanent magnets.
China’s position shows why.

In 2024, China accounted for about 60% of global mined production of magnet rare earths. Its share rose to 91% of refined output and 94% of global sintered permanent magnet production, according to the International Energy Agency (IEA).
Those figures reveal a structural problem in the global supply chain.
A country can develop a rare-earth mine and still depend on processing capacity elsewhere before its material becomes an industrial input.

The mine is only the beginning.
The Processing Gap Is the Real Bottleneck
Rare-earth production involves a long chain of industrial processes.
After extraction, ore is crushed and concentrated. The material then goes through chemical upgrading and separation.
Separation is particularly important. It converts mixed rare-earth feed into individual oxides.
Those oxides can then be converted into metals and alloys before entering magnet manufacturing.
The IEA describes separation as the technical core of rare-earth processing. The full chain runs from extraction and beneficiation through chemical upgrading, separation, metal refining, alloying and magnet manufacturing.
Each stage requires specialised technology, equipment, skilled workers and capital.
That makes rare-earth diversification fundamentally different from simply opening another mine.
The gap becomes clear when planned capacity is compared across the supply chain.
By 2035, announced projects outside the leading producer could deliver more than 50,000 tonnes of mining capacity. Planned refining and separation capacity remains below 40,000 tonnes. Downstream capacity for rare-earth metals, alloys and finished magnets is only around 18,000 tonnes on a rare-earth-content basis.
The message is straightforward:
More ore does not automatically create a more independent supply chain.
Why the “New Oil” Comparison Only Goes So Far
Rare earths are often described as the “new oil” because control over supply can create economic and strategic leverage.
The comparison is useful, but only to a point.
Oil is primarily extracted, transported and consumed as an energy commodity. Rare earths are industrial inputs that must pass through several specialised processing stages before they become useful components.
The strategic question is therefore not simply:
Who controls the resource?
It is:
Who controls the industrial capability between the resource and the finished product?
That distinction changes how supply security must be measured.
For rare earths, the factory can be as strategically important as the mine.
Magnets Are Where the Supply Chain Becomes Concentrated
Permanent magnets sit at the centre of this problem.
Neodymium-iron-boron magnets use neodymium and praseodymium as their principal rare-earth elements. Dysprosium and terbium can also be used to improve performance in demanding applications.
These magnets are used in electric motors, wind turbines, industrial equipment, electronics, aerospace and defence applications.
China’s dominance is particularly pronounced at this stage.
Its share of global sintered permanent magnet production increased from about 50% in 2005 to 94% in 2024, according to the IEA.
That concentration has also created economies of scale.
Large production volumes support established supply networks, specialised skills and a deep customer base. New producers outside China therefore face more than a technology challenge.
They have to build an industrial ecosystem.
Metallisation Adds Another Bottleneck
One of the less visible constraints sits between refined oxides and magnet production.
This is the metallisation stage.
Refined rare-earth oxides must be converted into metals, alloys or powders that can be used in magnet production. The IEA identifies this stage, alongside magnet manufacturing, as one of the most acute constraints on supply-chain diversification.
This matters because a country can have access to separated rare-earth oxides without having the capability to turn those materials into the inputs required by magnet manufacturers.
In other words, the supply chain can still break downstream even after a country solves the mining and separation problem.
Yttrium Shows That the Risk Is Broader Than Magnets
The supply risk also extends beyond the rare earths most closely associated with permanent magnets.
Yttrium is an important example.
Technically, yttrium is not a lanthanide, but it is generally grouped with rare-earth elements because of its similar chemical behaviour and natural association with them.
Its applications include aerospace, semiconductors, lasers and thermal-barrier coatings used to protect jet-engine components from extreme heat. Recent export controls have highlighted the vulnerability created by concentrated supply.
The IEA includes yttrium among the materials with high exposure to supply risk, reflecting its concentrated supply, limited alternatives and strategic applications.
The lesson extends beyond yttrium.
A supply chain does not need to lose large volumes of material to create an industrial problem. A relatively small amount of a specialised input can become a serious bottleneck when manufacturers have few qualified alternatives.
The US and Its Allies Are Building Alternatives
Investment outside China is beginning to change the supply map.
New projects in the United States and increased production in Malaysia reduced China’s share of global rare-earth refining from more than 90% in 2023 to about 85% in 2025, according to IEA data reported by Reuters.
But diversification remains incomplete.
The IEA says that if planned projects are delivered, China’s share of global rare-earth refining could fall to about 70% by 2035.
The downstream gap remains larger.
The IEA estimates that meeting projected demand for magnet rare earths outside China by 2035 would require substantial additional capacity. Even after planned expansions, existing and announced projects outside the dominant supplier would cover only about half of projected mining demand, around one-quarter of refining demand and well below 20% of magnet demand.
That is the central investment challenge.
Building mines without matching them with refining, metallisation and magnet capacity can leave a supply chain dependent on the same downstream infrastructure it was supposed to replace.
The Economics Make Diversification Harder
Building alternative supply chains also comes at a cost.
Across critical-mineral refining projects, the IEA estimates that capital costs outside dominant suppliers can be 20% to more than 150% higher. Operating costs are, on average, around 50% higher.
Rare-earth projects face additional challenges involving specialised equipment, technical expertise, workforce development and long project timelines.
The IEA also notes that outside China, only a limited number of suppliers provide some of the equipment needed for rare-earth processing, creating potential cost and lead-time constraints.
That means diversification cannot happen simply because governments announce new mines.
Projects need financing, technology, customers, qualified production and long-term policy support.
Recycling Can Add Another Source of Supply
Recycling will not eliminate the need for mining, but it can reduce pressure on primary supply.
The IEA estimates that recycling could reduce the need for primary rare-earth supply by up to 35% by 2050. Manufacturing scrap currently provides most secondary rare-earth supply, while future growth in electric vehicles, wind turbines and electronics could create larger sources of recoverable material.
For countries building regional supply chains, recycling therefore offers more than an environmental benefit.
It can become another source of strategically important material.
The Race Is No Longer Only About Who Owns the Mine
The rare-earth market is entering a different phase.
The strategic question is no longer only who has rare earths underground.
It is who can separate them, refine them, convert them into metals and alloys, manufacture high-performance magnets and recover them at the end of their useful life.
China spent decades building that integrated ecosystem.
Other countries are now trying to build alternatives.
The outcome will depend not only on the number of new mines announced, but also on how successfully those mines connect to processing plants, metallisation facilities, magnet factories and recycling systems.
That is why the rare-earth race has moved from the mine to the factory.
Control of processing and magnet manufacturing can give producers significant influence over the availability of usable rare-earth materials, even when mining capacity becomes more geographically diversified.
