Une tonne de cuivre, d'une mine à ciel ouvert chilienne jusqu'au fil — minerai à 0,5 %, un fondeur sur un autre continent, et l'or et le tellure qui en sont extraits en chemin. Suivre →
Suivez un lot, frontière par frontière
Tous les parcours →Le brut extra-lourd vénézuélien et l'Arab Light saoudien sont tous deux du « pétrole », et un seul d'entre eux peut être raffiné presque partout. Choisissez un matériau, choisissez son lieu d'extraction, et observez qui le détient à chaque frontière.

Venezuelan extra-heavy crude to diesel, asphalt and aluminium anodes
Oil so thick it will not flow down a pipe, and cannot be refined by most refineries on Earth.
Saudi Arab Light to petrol, almost anywhere
The same commodity, a fraction of the effort — because of what the molecule is.
Alberta oil sands: mined like ore, refined like oil
The only oil in the world that is dug up with a shovel and graded like an orebody.

Chilean brine to a battery in a car
The ore is water. The first year and a half of processing is done by the sun, for free.
Australian spodumene to a battery, the fast way
Eight weeks instead of eighteen months, at the cost of a great deal more energy.

New Caledonian laterite to stainless steel
An island that smelts its own ore, and pays for it with the most expensive electricity in the industry.
Indonesian laterite to a battery cathode
A country that banned raw ore exports and built the processing industry instead.

Chilean sulfide concentrate to Chinese cathode to a wire
Chile mines the most copper in the world. China refines the most. Those are not the same sentence.

Yttrium
Counted as a rare earth even though it sits elsewhere on the periodic table, because it behaves like one and is found with them.

Samarium
The rare earth in the magnet that works where neodymium cannot: very hot, or very cold, or in a place that must not corrode.

Antimony
A brittle, silvery metalloid used mostly to stop things burning, and in the primers and tracer rounds of ammunition.

Lead
A soft, dense, blue-grey metal that blocks radiation and stores charge cheaply — and that is also a well-documented neurotoxin.

Caesium
The softest metal, liquid on a warm day, and the element that defines the second.

Europium
The rare earth that glows red under ultraviolet light, and which for decades put the red in every colour television.

Palladium
Platinum's cheaper cousin for most of the twentieth century, then briefly more expensive than gold because petrol cars need it.

Cerium
The most abundant rare earth — more common in the crust than copper — mostly used as a polishing powder and in catalytic…
