InteractiveEight chainsStage-by-stageCountry shares

Each chain below shows the same six stages: what the material is at each point, what it is worth, what chemistry moves it forward, and who does that step.

Flip between them and the shared skeleton becomes obvious — which is the point, because the chemistry could hardly be more different.

2.2How to read it

Important

Country shares are approximate and move year to year. The shape of each chain is the durable part — which stage concentrates, and how much more concentrated each downstream stage is than the one before it.

Two patterns are worth looking for as you switch between materials. First, the country label changes as you move right along almost every chain: mining is one place, conversion is another. Second, the share figure usually rises as you move right — most starkly for rare earths, where mining is around 70 per cent and magnet manufacture is above 90.

The chapters that follow take each of these chains in turn and give the reactions, the economics and the failure modes behind the summary shown here.

Quick check: test yourself

1.What is the durable information in this figure, and what is not?

Show answer
The shape is durable: which stage concentrates, and the fact that downstream shares exceed upstream ones. The specific percentages are not — they move year to year with new capacity, policy and price, and should be read as orders of magnitude rather than as a ledger.

2.Flipping between copper and rare earths, what is the most striking difference?

Show answer
How much the concentration rises downstream. Copper mining is around 23 per cent for the leading country and refining around 45. Rare earths go from roughly 70 per cent at mining to about 90 at separation and above 90 at magnet making — the leverage compounds at every step.

Chapter summary

Frequently asked questions

How much do the eight chains actually differ?+

Less than the chemistry suggests. All eight move through the same six stages, and what changes is which stage is hard and who performs it. Copper’s difficulty is at stage 1 because grades are falling; lithium’s is at stage 3 because conversion chemistry is fiddly and slow; rare earths’ is at stage 4 because separating chemically identical elements needs a plant the size of a refinery; graphite’s is at stage 5 because rounding a flake wastes two-thirds of it.

Should the country shares be treated as precise?+

No. They are approximate, they move year to year, and they should be read as orders of magnitude rather than as a ledger. The durable information is structural — which stage concentrates, and how much more concentrated each downstream stage is than the one before it.

Ore to Vehicle is an original educational series on the battery and EV materials supply chain. Country shares, grades, prices and policy status are approximate, drawn from public reporting as of mid-2026, and move year to year — treat them as orders of magnitude rather than as a ledger, and verify before relying on them commercially.
