Everything is one chain
All supply chains →The same nine stages sit behind almost every physical product. Here they are for copper — click any stage to see what lives there.
-
01Raw material
What it is and where it sits in the ground
Copper in the ground — here as green malachite
-
02Deposit
The mineral that actually carries it
Chalcopyrite, the most important copper ore
-
03Mine
Who digs it up, and how
Escondida, Chile — the world's largest copper mine by output
-
04Processing
Crushing, floating, smelting
Froth flotation lifts copper minerals out of ground rock
-
05Refining
Getting to a usable purity
Copper anodes on their way to the refinery

Copper windings inside an electric motor

One tonne of copper, from a Chilean pit to a wire — 0.5% ore, a smelter on another continent, and the gold and tellurium that fall out on the way. Follow it →
Follow one consignment, border by border
All journeys →Venezuelan extra-heavy crude and Saudi Arab Light are both "oil", and only one of them can be refined almost anywhere. Pick a material, pick where it came out of the ground, and watch who holds it at every border.
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.
Or take the same chains without the borders
Materials the world is short of
The full critical minerals list →Criticality flag as designated in the USGS Mineral Commodity Summaries 2026. Leading-producer shares are 2025 estimates from the same source.
Nickel
A silvery metal that resists rust, which is why it goes into stainless steel — and, more recently, into the cathodes that give…
Lutetium
The last and densest rare earth, used in the crystals that detect gamma rays inside a PET scanner.
Tin
A soft metal with a low melting point, which is why nearly every electrical joint in every device is held together with it.
Caesium
The softest metal, liquid on a warm day, and the element that defines the second.
Lithium
A soft, silvery metal so light it floats on water, and the element that lets a rechargeable battery store a lot of energy for…
Titanium
A metal as strong as steel at about half the weight, which does not corrode in seawater or in the human body.
Holmium
The rare earth with the strongest magnetic moment of any element, used in the pole pieces of the most powerful laboratory…
Platinum-Group Metals
Six metals — platinum, palladium, rhodium, iridium, ruthenium and osmium — that occur together and are separated from each…
