Rare Earths Are Not Rare — So Why Is Everyone Stuck?

Because the bottleneck is not the ore but the processing. Deposits are spread across many countries, while the capacity to separate ore into usable material is concentrated in a few places — and that step is gated by environmental cost and decades of operating experience, not by geology.

Only one of the four steps is the ore — and the concentration is in the middle two

MiningRelatively dispersed
Australia, the United States, Brazil, Southeast Asia, and Africa all produce. This is the only step decided by geology, and the only relatively dispersed one — and it is the step that “we have our own deposits” refers to.
Separation and refiningHighly concentrated
The seventeen rare earth elements are chemically so alike that separating them takes hundreds of repeated solvent-extraction stages — energy-hungry, acid-hungry, and producing radioactive waste. The barrier sits here, and it is environmental and financial rather than a technical secret.
Materials manufactureHighly concentrated
Permanent magnets, cathode and anode materials, speciality alloys. Turning separated elements into usable component materials depends on yield and formulation built over decades — and neither ships with the equipment.
Final assemblyRelatively dispersed
Motors, sensors, battery modules, finished vehicles and equipment. The widest-spread step, and the only one most companies touch directly — you buy a module, and the minerals sit three or four tiers above it.

Highly concentrated — only a few places can do itRelatively dispersed — many countries participate

“We have our own deposits” refers to the top step — which happens to be the dispersed one and the least likely bottleneck. The concentration sits in separation and materials manufacture: a country can own the ore and still ship it elsewhere for processing, then buy the finished material back.

This is a classic chokepoint located in a process rather than at sea: escorting cannot reach it and stockpiling cannot cover it — ore can be stored, separation capacity cannot. Nor is the barrier a technical secret. It is willingness to carry the environmental cost and capital of that step, plus decades of operating experience. The first is a political decision; the second only accrues with time.

Which minerals count as “critical”, and who decides?

Critical minerals is a policy category, not a chemical one. Each country writes its own list, usually on three tests: essential to a strategic industry, concentrated in few sources, and without a near-term substitute.

Typical lists include lithium, nickel, cobalt, copper, graphite, and the rare earth elements — the first five underpin batteries and grids, while rare earths go into permanent-magnet motors, sensors, and missile guidance.

Lists change, and the change is itself information: a material is added when some industry has just discovered a dependency it never inventoried.

Why are rare earths called rare? Are they?

They are not. Rare earth elements are reasonably abundant in the crust; several are more common than copper. “Rare” refers to how seldom they form concentrated deposits, being usually dispersed within other minerals.

The difficulty is therefore not finding them but separating them. The seventeen elements are chemically so similar that pulling them apart takes hundreds of repeated solvent-extraction stages — a process that is energy-hungry, acid-hungry, and produces radioactive waste.

That is the whole story: the bottleneck is not geology but willingness to carry the environmental cost and capital of that step — which is a political decision rather than a technical one.

Where in the chain is the chokepoint?

The chain has at least four steps: mining, separation and refining, materials manufacture such as permanent magnets, and final assembly. Their concentration differs sharply.

Mining is relatively dispersed — Australia, the United States, Brazil, and Southeast Asia all produce. The concentration sits in the middle two steps. A country can own the ore and still ship it elsewhere for processing, then buy the finished material back.

This is a classic chokepoint, located in a process rather than at sea. It also explains why “we have our own deposits” is not a guarantee: the ore is yours and the capability is somebody else’s.

Why is it not being fixed? The subsidies have been flowing for years.

Three constraints bind at once. First, time: a new separation plant typically needs five to ten years from permit to steady output, and the permit itself carries the environmental fight.

Second, price. The market is small and highly volatile, and a dominant supplier can let prices fall as new capacity approaches start-up, so the new plant loses viability before it opens. This requires no unlawful act — only capacity and patience.

Third, process knowledge. Separation parameters, impurity control, and yield are decades of accumulated operating experience and do not ship with the equipment — the same difficulty as yield in semiconductors. So friend-shoring here is not simply relocating a plant; somebody has to be willing to fund the unprofitable years.

Three constraints bind at once — and a subsidy only partly clears the first

Constraint	Why it binds	Can a subsidy solve it?	What it actually needs
TimeFive to ten years from permit to steady output	A new separation plant needs environmental permitting, construction, commissioning, and tuning to stable yield. The permit carries the environmental fight, and its length is not the investor’s to set.	Partly. Money buys parallel construction and more people; it does not buy the permitting process or the physical time to commission.	Starting early, and starting before demand tightens — because breaking ground once it has tightened is already five years late.
PriceA small, volatile market	A dominant supplier can let prices fall as new capacity nears start-up, so the plant loses viability before it opens. No unlawful act is required — only capacity and patience.	No. A one-off capital subsidy addresses construction cost, while a price war targets a decade of operating revenue.	Demand-side instruments: long-term offtake agreements, price floors, procurement guarantees. Somebody has to commit to buying before anyone builds.
Process knowledgeDoes not ship with the equipment	Separation parameters, impurity control, and yield are decades of accumulated operating experience. The same equipment in different hands produces materially different purity.	No. This is the same difficulty as yield in semiconductors: a plant is a capital problem and yield an experience problem.	Real production. And real production needs a buyer, so it loops back to the row above — the three constraints are not parallel but interlocked.

Subsidies have flowed for years without matching capacity, because three constraints bind at once and differ in kind: money shortens part of the time, a price war needs demand-side instruments, and process knowledge only accrues through real production.

The last sentence of the final row is the point: the three are interlocked rather than parallel. Without a committed buyer there is no production; without production no yield accrues; without yield there is even less reason to commit. A single instrument does not break the loop — which is why the arrangements that work tend to be offtake agreements and price floors rather than larger construction grants.

What should a company actually inventory?

Trace to the third and fourth tiers. Critical minerals almost never appear on a first-tier purchase list — you buy motors, sensors, or battery modules, and the minerals sit upstream of those.

Watch the items with negligible cost share. The typical single point of failure is a material worth under one per cent of cost with two suppliers in the world — and procurement systems rank by cost.

Push “do we have a second source?” all the way to the common upstream. Two suppliers may buy the same magnet material from the same producer: the redundancy exists on the vendor list, not in the physical chain.

Terms used here

Critical Minerals — Minerals that are irreplaceable for particular industries and whose supply is concentrated in a handful of countries — rare earths, gallium, germanium, graphite, lithium. Criticality usually stems not from where deposits lie but from where refining and processing sit: extraction can be diversified, whereas spec-compliant refining capacity takes years and extensive permitting to establish. That lag is the hardest element for policy to compress.
Chokepoint — A narrow passage through which global trade or energy transport must pass, with no equivalent alternative — the Strait of Hormuz, Malacca, Suez, Panama. The risk does not require closure: rising insurance rates, added voyage days from rerouting, and delay costs typically reshape trade economics well before any actual interruption occurs.
Single Point of Failure — A node whose failure halts the entire chain. It is rarely the most expensive or most visible link — more often a specialty chemical, a sole packaging facility, or a particular test instrument accounting for a trivial share of cost. Mapping these is hard because they typically sit at tier three or four, while most companies have visibility only to tier one.
Friend-shoring — Relocating production and sourcing to politically aligned countries rather than optimizing for proximity or cost. It assumes political alignment secures supply more reliably than commercial contracts — an assumption with a shelf life, since elections, leadership changes, and intra-alliance divergence redraw the list of "friends". Capacity investments justified on political grounds typically have payback periods longer than political cycles.
