Key findings
- China holds roughly half of the world’s copper-smelting capacity — about 45 to 50%. ICSG
- The 2025 benchmark fee for smelting copper fell to $21.25 a tonne — a historic low that is bankrupting Western smelters. Fastmarkets
- Indonesia banned nickel-ore exports in 2020 to force processing onto its own soil. Indonesia’s Energy Ministry (MEMR)
- The Democratic Republic of Congo mines about 70% of the world’s cobalt. USGS
- China refines 55 to 65% of the world’s lithium. Benchmark Mineral Intelligence
A mine without a smelter is financial servitude.
That sentence explains more about 21st-century power than most summit communiqués.
Raw ore is worth a fraction of refined metal. The difference — the margin, the jobs, the leverage — lives in the furnace. Whoever owns the furnace sets the terms for everyone who digs.
Copper just proved it. Treatment and refining charges — the fees smelters charge miners — collapsed to historic lows in the 2025 benchmark negotiations, around $21.25 a tonne. Spot terms went lower still.
Translation: smelters are so hungry for concentrate that they are practically working for free.
Why? Because China built roughly half the world's copper smelting capacity — and keeps building.
Western smelters cannot compete. Energy costs in Europe, environmental compliance, three decades of offshoring the dirty middle of the supply chain. One by one they curtail, close, or beg for state aid.
So Western miners do the only rational thing: they load concentrate onto ships and send it east. The ore leaves. The metal comes back — at a markup, on someone else's terms.
That is the trap. You can own the mine, wave the flag over it, nationalize it twice — and still be a price-taker.
Nickel tells the same story with a Southern twist. Indonesia banned nickel ore exports in 2020 and forced the smelters onshore. Chinese capital — Tsingshan most visibly — built them.
Jakarta kept more value at home. But the processing technology, and much of the offtake, answers to the east.
Cobalt is the purest case. The Democratic Republic of Congo mines roughly 70% of the world's cobalt. Almost all of it is refined in China.
Lithium, the same. Australia and Chile dig it; China refines well over half of it.
And here is the detail the thesis demands: smelters produce sulphuric acid as a byproduct. Sulphuric acid is what Morocco needs to turn phosphate rock into fertilizer.
A smelter without acid is a dead building. A fertilizer giant without acid is hostage. The midstream chains link to each other — copper to acid to food.
The West is now trying to rebuild what it dismantled: smelter subsidies, critical-minerals clubs, "friend-shored" refining.
But a smelter takes years to permit and billions to build. China spent twenty years building the world's furnace fleet while the West financialized.
You cannot sanction your way out of a furnace you no longer own.
Western lens
Western coverage — the Financial Times, Reuters, Bloomberg — reads the smelter trap as a strategic vulnerability decades in the making.
The argument: offshoring refining was the original sin of deindustrialization; rebuilding requires subsidies, permits, and patience.
The answer: critical-minerals partnerships, allied refining capacity, stockpiles.
The risk is dependence. The cure is industrial policy — the very thing the West mocked for thirty years.
Eastern lens
Eastern coverage — Xinhua, the South China Morning Post — reads the same facts as industrial policy vindicated.
The argument: China built refining capacity because it planned to; the low TC/RCs are overcapacity, not conspiracy.
Western talk of "overcapacity" is framed as sour grapes — the market working exactly as designed, just not for the designers.
The risk is protectionism. The cure is more furnaces, more integration, more scale.
Global South lens
The South — Jeune Afrique, the EastAfrican, the Jakarta Post — reads the smelter trap as the oldest story in the book, retold.
Indonesia's ore ban is the model: no more raw exports, smelt at home, keep the margin. Kinshasa and Lusaka are watching.
But the Indonesian lesson has a second half: the furnaces came with foreign capital and foreign offtake.
The question isn't mine versus smelter. It's whose smelter, on whose terms.
The consensus
- What we agree on
- All three blocs agree: refining concentration is the real chokepoint. China holds ~half of copper smelting and the dominant share of cobalt, lithium and graphite refining. Nobody disputes the furnaces.
- What we don't agree on
- On whether this is market efficiency or structural capture. The West sees a vulnerability to fix; the East sees competence to envy; the South sees a negotiation to win.
- What we know
- 2025 copper TC/RCs hit historic lows near $21.25/t. Indonesia's 2020 ore ban forced onshore smelting. The DRC mines ~70% of cobalt; China refines the overwhelming majority of it.
- What we don't know yet
- Whether Western smelter subsidies arrive before more capacity closes. Whether the DRC or Zambia can replicate Indonesia's ban without Indonesian-scale capital. How the sulphuric-acid linkage reprices phosphate.
- What we expect
- More ore-export bans from the South. More furnace-building in the East. Western miners shipping east for years — because the ships are already sailing.
