De Wolfram-Crisis Bestaat Niet

On By konstapelIn Uncategorized

de “wolframcrisis” is geen grondstoffenschaarste , maar een bewust gecreëerd knelpunt in de verwerkingsfase: China controleert de omzetting van erts naar ammoniumparatungstate (APT), waar de prijs sinds 2025 enorm door steeg.

De Verenigde Staten hebben daarop met eigen beperkingen gereageerd, waardoor een politiek bepaalde prijsvloer is ontstaan die vooral Europese recyclers raakt.

De oplossing ligt niet in grootschalige mijnbouw, maar in kleinschalige, regionale ketens: herslijpen, zinkrecycling en directe carbideproductie, die China’s knelpunt omzeilen.

Europa moet daarvoor zijn eigen wolfraamschroot in de eigen keten houden, in plaats van het te exporteren naar de Verenigde Staten, die hun schroot sinds augustus 2026 volledig voor de eigen markt reserveren.

NB: Tungsten en wolfram zijn exact hetzelfde chemische element: het symbool W.

Tungsten is everywhere and nowhere. It sits in the drill that cuts a printed-circuit board, the insert that machines a crankshaft, the tip of an armour-piercing shell and the wall of a fusion reactor. In 2026 the metal became a byword for scarcity. Its price rose roughly ninefold in under two years. Dart sets cost thirty percent more. A metalworking firm in Zoetermeer speaks simply of “the tungsten crisis.”

Yet the ground is not the problem. World reserves exceed 4.7 million tonnes. At the 2025 mining rate of 85,000 tonnes, that is more than fifty years of supply. The scarcity sits in one step of the chain: the conversion of ore into ammonium paratungstate (APT), the white salt from which every tungsten product begins. China controls about 85–86 percent of APT capacity, according to S&P Global and the Centre for Materials & Resilience — figures that remain single-sourced and could not be independently verified.

The crisis, in other words, is a node, not a resource. And the node has been closed deliberately, twice.

2. How Beijing closed the gate

China’s Announcement No. 10 of 4 February 2025 placed specific tungsten items under export licence: APT, tungsten oxides and carbide powder, heavy alloys above 17.5 g/cm³, massive tungsten pieces above set dimensions, and the production technology for all of these. The controls sit precisely on the node. Concentrate, metal powder and finished tools are absent from the list. China mines 67,000 of the world’s 85,000 tonnes (79 percent); the prefecture of Ganzhou says of itself: think of Ganzhou with tungsten as you think of the Middle East with oil.

Beijing then locked the gate shut. On 26 December 2025, the Ministry of Commerce published its state-trade list for 2026–2027: only fifteen companies in all of China may legally export tungsten. Unlike a negotiable quota, a state-designated exporter list is difficult to contest or unwind. Chinese APT exports collapsed from 782 tonnes in 2024 to 243 tonnes over January–November 2025, with 57 percent of that going to Japan alone; by early 2026 they approached zero, and total tungsten exports fell 34 percent year-on-year in the first two months of the year.

The market responded as a tree does when its trunk closes. Tungsten concentrate rose from $750–850 to $2,500–2,800 per metric ton unit (mtu), where it has held since late May 2026. APT in Rotterdam traded above $3,000 per mtu. The International Energy Agency called tungsten the fastest-rising strategic metal.

Here is what the price is not. It is not an energy price. Making tungsten carbide from concentrate takes about 10 kWh of electricity per kilogram of tungsten; the step from concentrate to APT takes about 1.9 kWh. At €0.15 per kWh, energy was four percent of the APT price at the start of 2025. By 15 October 2026 it was roughly half a percent, and a tenth of that for the APT step itself. Nothing became costlier to make. One gate closed, and the price followed it up.

3. Washington answers — and builds a second gate

The conventional reading of this crisis stops at Beijing: the price is geopolitical, and what one political decision raised, another can lower. That reading is now incomplete. In 2026 the United States built its own gate, on the other side of the Atlantic market.

On 27 August 2026, the Bureau of Industry and Security published a temporary final rule under the Defense Priorities and Allocations System. American sellers of tungsten waste and scrap (Schedule B 8101.97) and battery black mass must allocate one hundred percent of their monthly sales to US buyers. Exports are prohibited unless BIS grants an exception; a narrow pathway exists for material refined abroad and returned. The rule runs to 27 August 2027 and can be extended. Washington used the Defense Production Act, not standard export-control law, and its logic is unambiguous: tungsten has not been mined commercially in the United States since 2015, so scrap is one of the few domestic sources it can secure immediately.

A second measure follows on 1 January 2027, when US defence procurement rules will generally prohibit tungsten metal powder, heavy alloy and covered components sourced from China, Russia, North Korea or Iran — reaching back through the supply chain to ore and recycled material. A July 2026 executive order tightened the exemptions. Commentators have called this “scrap nationalism”: Washington adopting Beijing’s playbook. The label is fair, and it matters for one group above all — European recyclers.

The consequence is a policy-driven price floor with two supports. If Beijing reopens its gate, the price will not simply fall back, because the American system now excludes Chinese tungsten from defence supply and keeps American scrap at home. Any business case for Western tungsten built on today’s price rests not on one political decision but on two, in two capitals, pulling in the same direction. For mining investors, the old risk remains — a reopened Chinese tap — but it is now paired with a new certainty: a structurally protected Western demand base. The two do not cancel out. They make the price less informative and the commitment longer.

4. History’s warning about trunks

Western tungsten mining has been paid for in wartime, and punished in peacetime. The largest tungsten mine outside China, in Australia, opened in the First World War, reopened just before 1939, produced through the Korean and Vietnam wars, closed in 1990, and is open again now. Ten years ago China sold tungsten below cost and Western mines went under water.

Large projects are again under way. H.C. Starck, owned by Mitsubishi Materials since December 2024, invests about €50 million in Goslar, lifting capacity by nearly half to about 7,000 tonnes a year by 2028; some eighty percent of its feed is already recycled material. Mitsubishi Materials doubles APT capacity in Akita, Japan, by April 2029. Almonty began processing at Sangdong in Korea in July 2026 and has certified the plant for commercial production, with nearly half its output allocated to munitions production in Pennsylvania. Tungsten West is commissioning at Hemerdon in England. Kazakhstan’s Boguty began producing in 2025.

These plants make APT outside China. That is valuable. But they are still trunks: single, large, thirty-year commitments. They carry the same risk the Australian mine carried. Large capacity outside China needs a floor under the price — long-term offtake, strategic stock, or public ownership. Absent that floor, history repeats.

5. Europe pays for a mine and exports its own loop

The European Union has answered the crisis with geology. In its second batch of strategic projects under the Critical Raw Materials Act (9 October 2026), the Commission approved 46 new projects across 16 member states, including three on tungsten. The Borralha mine in Portugal — held by Mineralia, with Allied Critical Metals advancing the neighbouring project — is the only tungsten extraction project in the batch. A correction to earlier analysis of this batch: a tungsten processing plant is in fact included. “EU APT Tungsten Plant,” promoted by Abenójar Tungsten S.A., is planned in Puertollano, Spain — the first EU APT project in the programme. No tungsten recycling project was selected. That is the gap.

The gap is measurable. In 2025 the EU exported 4,911 tonnes of tungsten waste and scrap outside the Union, two-thirds of it to the United States. The Netherlands alone exported 928 tonnes, mostly to Germany, and is a net scrap exporter. Tungsten scrap holds far more tungsten per tonne than any ore. Half of Europe’s carbide already comes from recycling, and the European recycling sector says its capacity is “approaching its limits.”

Meanwhile, every major player except Europe is closing its loop. Japan’s machine-tool builders discourage carbide scrap from leaving the country. China draws on recycled feedstock to offset reduced mining quotas. And since 27 August 2026, the United States — destination of two-thirds of Europe’s scrap exports — requires that American scrap be sold only to American buyers. Europe’s richest secondary ore is flowing toward a market that no longer releases its own.

EU policy has noticed metal scrap in general, but not tungsten in particular. The RESourceEU plan proposes export limits on scrap of magnets, aluminium, possibly copper and battery black mass; tungsten is not named, even though the same programme calls for keeping metal stocks within the Union. Tungsten scrap remains on the “green list” of wastes (B1010), and from 21 May 2027 it may go outside the OECD only to listed countries — a restriction that does not touch the flow to the United States. On 18 September 2026 the Commission published its draft country list under the revised Waste Shipment Regulation; the broader metal-scrap framework is tightening, but tungsten scrap to the US remains unaffected. The Dutch list of critical raw materials (7 July 2026) includes tungsten and contains no measure on scrap.

The correction is obvious and cheap relative to a mine. Fund the loops and the processing, not only the extraction. Treat clean carbide scrap as a resource, not a waste. Keep tungsten scrap in the European loop, as is already proposed for magnets and aluminium. The European Parliament votes on the CRMA amendment on 20 October 2026 — tomorrow, as this is written.

6. Small loops beat the long chain

The routes that bypass the Chinese node are not large. They are small, proven, and they pay at today’s prices.

Regrinding. A worn solid-carbide drill can be reground several times. An independent study finds that more than sixty percent of original tool life returns; vendors claim 85–95 percent. A regrind costs about thirty percent of a new tool. Per unit of cutting work, that is 64–73 percent less new carbide, with no new technology required.

Keeping carbide as carbide: zinc recycling. Worn carbide is placed in molten zinc at 450–500 °C. The zinc swells the cobalt binder, the piece falls apart, the zinc is distilled off and reused, and the carbide is milled to powder. The grain is never rewritten. It costs about 3.3 kWh per kilogram of tungsten — a third of the primary route. Recycled powder is not on the Chinese control list.

Supplier take-back, now at scale. Sandvik reports 70 percent less energy and 64 percent less CO₂ for recycled carbide, aims to buy back ninety percent of its insert volume, and has now gone further: its PowerCarbide grades will carry up to 75 percent recycled cemented carbide as standard across global drill-bit production through 2026–2027, using closed-loop extraction units stationed on every continent. Its Austrian subsidiary Wolfram Bergbau already makes half its products from recycled material. Ceratizit sells a grade with more than 99 percent recycled content at 56 percent lower carbon footprint than its conventional equivalent.

Making carbide straight from ore. Polini and colleagues (2021) milled tungsten concentrate with carbon black, heated it for six hours at 1,150 °C, leached it, and obtained tungsten carbide of 99 percent purity with a 92 percent extraction yield. The route skips APT, oxide and metal. It uses half the energy, four reagents instead of fourteen, and less than half the waste. The carbide sintered into hard metal of industrial quality. The Italian firm F.I.L.M.S. holds the patent. Verification research finds no industrial-scale deployment yet; the route remains laboratory-proven — but so did every other route once.

The economics now support the loop. Carbide scrap fetched under €20 per kilogram in 2023, about €75 in January 2026, peaked at €130–140 in March 2026, and settled at €65–80 by mid-October 2026. European prices in 2026 ran at 80–100 €/kg. Recycling capacity, not scrap availability, is the binding constraint: processing runs at capacity, and new facilities take two to three years to build and qualify. The US Department of Energy has already put an $11.5 million grant behind domestic carbide recovery.

This is the shape of the answer. A zinc furnace serves a region. A direct carbide line can stand beside a mine. A regrind service needs a workshop and a spare-tools bin. Against one trunk, a net of small meshes — each mesh cheap, fast, and outside the reach of Announcement No. 10.

7. The substitutes are ready; the incumbents are not

For many functions, tungsten already has a working alternative. Silicon nitride ceramics machine cast iron three to four times faster, without tungsten. Hard turning with PCBN instead of grinding uses ten to fifteen times less energy per volume removed, and one lathe replaces several grinders. Ti(C,N) cermets finish steel at higher speeds. SiAlON ceramics cut nickel alloys at four times the conventional speed. Diamond tooling lasts four times longer in aluminium and composites. Lead and steel do most shielding work at a fraction of the cost.

In semiconductors, the substitution has crossed from possibility to plan. SK hynix has verified 375-layer NAND flash and will begin mass production by the end of 2026, replacing part of the tungsten in its word lines with molybdenum — chosen for lower resistance as wiring narrows. Samsung was first to introduce molybdenum in metal wiring; Micron has adopted it; future 480- and 604-layer generations will rely on it more heavily. Lam Research and Tokyo Electron supply the deposition equipment. A materials cycle that lasted a quarter-century is ending.

Two caveats keep this in proportion. First, the volume is small: industry expectations run at 25–80 tonnes of molybdenum per year for memory between 2027 and 2030. Technology routes around the problem; it does not relieve the tungsten market. Second, molybdenum is not a repeat of tungsten’s geography: China mines 37 percent of molybdenum, against 79 percent of tungsten, and its export control on molybdenum covers only fine powder for missile parts.

Yet the cutting-tool industry’s answer to the 2026 crisis has been price rises — up to sixty percent on some tool lines — and carbide grades with less tungsten, not a shift to the tungsten-free tools it already sells. Ceramics held 8.5 percent of the cutting-tool market in 2011; nothing in the reviewed sources shows that share moving now. The obstacle is not physics. It is habit, installed machines, and a supply chain built around one material. Firms that adopt the alternatives now buy independence from the node.

Two functions have no plentiful alternative: density combined with hardness, as in armour-piercing ammunition, and the wall of a fusion reactor. These are the places for strategic stock, not substitution.

8. No way out through the elements

Could tungsten be made from something else? No route works at acceptable cost, and the physics has now been computed in detail.

The state road: some stable atoms become unstable when stripped of their electrons — measured for dysprosium-163, rhenium-187 and thallium-205. Computed at every charge state, no natural nucleus opens a path to tungsten. The nearest candidate, tantalum-181, stays closed by 138 keV even when fully ionised.

Capture: tantalum-181 captures a neutron and becomes tungsten. In a strong reactor flux, a thin tantalum foil converts 4–9 percent per year. But every tungsten atom costs one neutron, which puts the energy at a minimum of 2.6 million kWh per kilogram — against roughly 10 kWh for the chemical route. And tantalum is 34 times scarcer than tungsten.

One reverse effect is worth a footnote. A fusion reactor’s tungsten wall slowly becomes rhenium and osmium: about 0.27 tonnes of rhenium per gigawatt-year, three-tenths of a percent of world output. Fusion consumes the very metal its wall is made of — one more reason the reactor wall belongs on the short list of functions with no substitute.

9. What it means, for whom

For governments and the EU. Fund loops and processing, not only mines. Add tungsten scrap to the scrap-export measures already drafted for magnets and aluminium — before the flow to the United States, now a closed American loop, becomes irreversible habit. Build strategic stock where no substitute exists: defence and fusion. Support the Puertollano APT plant and Borralha, and match them with the recycling capacity that no strategic project yet provides.

For investors. Mining shares have risen three- to tenfold. Their value rests on a price set by two export regimes, not by cost. History shows what a reopened Chinese gate does to uncovered capacity; the American floor shows what it does to prices for compliant, non-Chinese supply. Processing and recycling capacity outside China — with price protection and qualification — is the sounder exposure.

For entrepreneurs. The openings are small and regional, and the constraint is now capacity: regrind services; scrap pools that reach the half-tonne lots the market requires; zinc recycling near clusters of tool users; qualification partnerships for new recovery lines. Each is a two-to-three-year build with a price environment that pays for it.

For large manufacturers. Specify by function, not by habit. Ceramic, PCBN and cermet tools already do part of the work without tungsten. Return all carbide to the supplier. Buy recycled grades — they are now standard, certified and cheaper in carbon as well as in exposure.

For the people involved. In Borralha, opposition is growing, not fading: the environmental assessment drew 653 submissions, a residents’ collective — “Cávado Sem Minas” — has taken the case to protest and court, and the mine’s EU designation has intensified the contest between Lisbon, Brussels and the people who drink the water. In Rwanda, Trinity Metals employs more than 6,500 people, ninety-nine percent Rwandan. At the machine, a loop means separate bins, clean scrap, a spare stock of tools during regrinding, and one person who owns it. Anyone grinding carbide in-house faces the EU’s proposed cobalt exposure limit of 0.01 mg/m³. The circular economy has working conditions, too.

10. The shape of the answer

The tungsten crisis is often described as a shortage. It is better described as a design flaw, exposed. A century of supply chain design concentrated the world’s tungsten in one processing step, in one country — a trunk carrying every leaf. China closed the trunk; the United States is now closing its own; each closure raises the price of every alternative route.

The way out was never going to be a bigger trunk. It is the net: reground tools that never re-enter the chemical chain, zinc furnaces that keep carbide as carbide, suppliers who take their own products back at 75 percent recycled content, a one-step carbide line waiting for its first industrial owner, ceramics and cermets already cutting cast iron without tungsten, and molybdenum quietly replacing tungsten in memory chips. None of these routes needs thirty years. None of them passes through the node. All of them need the one thing that policy has not yet given: Europe’s own scrap, kept in Europe’s own loop.

The ground holds fifty years of tungsten. The gate holds the price. The net, small mesh by small mesh, is how the West walks around the gate.
