Hafnium: Extraction
Why hafnium has no ore and hides inside zircon sand
What this tab covers How it is mined, drilled or grown, and processed into a tradeable form: the main methods compared, their unit economics, by-products, and the companies that do this work globally and in India.Hafnium never forms its own ore. It sits inside zircon, the zirconium silicate mined from heavy-mineral sands alongside titanium minerals in Australia, South Africa, Mozambique and elsewhere. Zirconium and hafnium are chemical near-twins. They are separated mainly because nuclear-grade zirconium must be almost free of neutron-absorbing hafnium. Hafnium is therefore a by-product of making reactor zirconium, with companionality around 95%. In the United States, one producer in Oregon and one in Utah make zirconium and hafnium metal from chemical intermediates.
Hafnium is not mined for itself. It is pulled out only when zirconium is purified for nuclear fuel cladding, because hafnium absorbs neutrons and must be removed. Supply therefore depends on how much nuclear-grade zirconium is made, mainly in France, the US, China and Russia. The separated hafnium is reduced to sponge, refined and sold to superalloy makers and chip and chemical producers. Total supply is only 70-90 t a year, which is why prices can triple in a year.
Methods compared
| Method | Share of supply | Typical scale | Recovery / efficiency | By-products | Unit cost |
|---|---|---|---|---|---|
| By-product of nuclear-grade zirconium production | essentially all primary supply; France 49%, US 44%, China 5%, Russia 3% of processing (EU CRM 2023) | world pure metal supply 70-75 t/yr (Argus 2025); Russia makes a couple of tonnes a year (Reuters 2023) | about 50 t of zirconium processed per tonne of hafnium (Reuters 2023) | hafnium is the by-product; the main product is nuclear-grade zirconium | n/a |
| Reduction to sponge and refining to metal and compounds | n/a | US imported 72 t of unwrought hafnium and exported 15 t in 2025 (USGS) | n/a | magnesium chloride (recycled) | unwrought hafnium $3,800/kg (2025 annual average, Argus via USGS) |
| Recycling | EU end-of-life recycling input rate 0% (EU CRM 2023); US hafnium metal recycling minimal (USGS) | n/a | n/a | n/a | n/a |
How each method works
By-product of nuclear-grade zirconium productionZircon is chlorinated and the mixed chloride is separated. In one route, zirconium and hafnium thiocyanate complexes are split by solvent extraction in organic solvents; in another, the chlorides are separated by extractive distillation in molten salt. Hafnium leaves as a purified chloride or oxide.
No extra mining needed; supply cannot rise unless more nuclear zirconium is made.
EU CRM study 2023; Argus (Oct 2025); Reuters via Kitco (Feb 2023) Reduction to sponge and refining to metal and compoundsPurified hafnium chloride is reduced with magnesium in a Kroll reactor, then vacuum-distilled to sponge. Sponge is electron-beam or arc melted, or refined further by the iodide crystal-bar process for electronics. Chemical plants convert it to high-purity tetrachloride and oxide.
Small, specialised plants; purity requirements for chips are rising.
USGS MCS 2026 RecyclingSuperalloy revert and machining scrap is remelted with its hafnium content; little hafnium metal is recovered as such.
Recovers value within superalloys but does not add free hafnium supply.
EU CRM study 2023; USGS MCS 2026 Unit economics are indicative ranges from the sources named; costs vary widely by deposit, region and year.By-product supply
Companionality is about 95%: hafnium comes from zirconium purification. Supply follows nuclear-grade zirconium output and reactor construction, not hafnium prices, so a 300% price rise in 2022-23 brought little new supply. Russian exports were blocked by missing dual-use licences in 2023 and Chinese exports have been curbed by dual-use controls since late 2024 (Reuters 2023; Argus 2025). USGS publishes no world hafnium production or reserves.
Share produced as a by-product
About 95% of primary supply comes as a by-product of zirconium (Nassar, Graedel & Harper 2015, approximate).Who does it: global

India has zircon from IREL and KMML and makes nuclear-grade zirconium for its own reactors, but publishes no hafnium output and does not appear among world suppliers (EU CRM 2023). Hafnium is on India's 2023 critical list.
