Where does zirconium come from?

Zircon trade splits into a China-bound stream and a higher-priced stream led by Australia. In 2024 China took 48% of world import value of zirconium ore and concentrate (HS 261510) but 68% of import weight, at $794 per tonne (CEPII BACI, weight share and unit values from the customs table). It took 62% of South Africa's exports but only 13% of Australia's. Australian ore averaged $2,181 per tonne, Mozambique's $610. The customs line does not show grade or zircon content, so these gaps are patterns to read with care rather than measured quality differences.

At least four African exporters shipped more weight than USGS credits them with mining. In 2024 South Africa's exports of 559,569 tonnes were 1.9 times its 290,000 tonnes of mine output, Mozambique's were 1.5 times its output, Senegal's 1.4 times and Sierra Leone's 2.8 times (71,174 tonnes against 25,000). Nigeria exported 80,932 tonnes with no line in the USGS mine table, while Australia's 122,822 tonnes were 31% of its 400,000 tonnes mined (our arithmetic on CEPII BACI net weight and the 2024 figures in USGS MCS 2026). Some exporters ship material that originated elsewhere, and USGS rounds some national figures, so the data show a mismatch without explaining it.

Buyers outside China are spread across suppliers. In 2024 the largest supplier's share of zircon ore import value was 59% (Australia) for Japan, 45% (South Africa) for South Korea, 44% (South Africa) for the United States, 31% (South Africa) for the European Union's imports from outside the EU and 28% (Australia) for India, all below the 65% benchmark in the supplier exposure report (CEPII BACI). The United States also mines: it produced 100,000 tonnes of concentrate in 2025, and USGS puts its net import reliance at less than 25% for zirconium ores and concentrates (USGS MCS 2026, rounded).

This page is about zircon concentrate, the mineral product from which zirconium is made. In 2025 Australia produced 400,000 tonnes of zirconium mineral concentrates, 33% of the world's 1.2 million tonnes (USGS MCS). South Africa followed with 23% and Mozambique with 13%, so the top three account for 69%. China (8.3%) and the United States (8.3%) come next, the top five account for 86%, and 9 countries are listed. USGS's table rounds the world total to the nearest hundred thousand tons, and its narrative text separately says world production fell by 12 percent to an estimated 1 million tons in 2025, so this page does not quote a world year-on-year change from the table. The largest country changes in the table are a rise for Mozambique and falls for Indonesia and South Africa. The listed countries and the "other countries" line sum to slightly more than the rounded 2025 world total. USGS revised its 2024 figures for Australia and Mozambique in the 2026 edition using government reports, and it rounds the United States figure to the nearest hundred thousand tons to avoid disclosing company data.

Zircon is zirconium silicate. It occurs in heavy-mineral sands, sedimentary deposits of grains denser than ordinary quartz sand. The USGS deposit model for coastal heavy-mineral sands says rocks containing heavy minerals weather and erode inland, rivers carry the grains to the coast, and waves, tides, currents and wind sort them by size and density; it also describes zircon as frequently recovered as a coproduct with the titanium minerals. The Zircon Industry Association (ZIA) says most zircon sand is mined in Australia and Africa. USGS describes United States output as a coproduct of heavy-mineral sands mining in Florida and Georgia, plus one company reprocessing sands tailings in California. Tronox, a miner and pigment maker, calls zircon in its 2025 annual report a co-product of mining mineral sands for titanium feedstock, and a relatively small part of the deposit with a relatively high value.

Reserves stand at 77.5 million tonnes of zirconium oxide (ZrO2) content in 2025, the sum of the countries USGS lists plus its "other countries" line, while USGS itself prints the world figure only as more than 70,000 thousand tons, with Australia holding 71% (55 million tonnes), South Africa 7.6%, Indonesia 4.4%, Senegal 3.4% and Madagascar 2.7% (USGS MCS). Mozambique is the third-largest miner but not among the five largest reserve holders. USGS notes that Australia's reserves under the JORC reporting code are lower than its headline figure.

Two cautions apply. Output is gross weight of concentrate while reserves are ZrO2 content, and USGS converts between them in its US statistics with a fixed 65 percent factor, so this page does not divide reserves by output to produce years of supply. And USGS's chapter covers zirconium and hafnium together, while the data here is zircon concentrate only. USGS says estimates of hafnium reserves and world hafnium production were not available. Hafnium is a separate US-list mineral that this site does not cover.

In 2024 South Africa was the largest exporter of zirconium ore and concentrate (HS 261510) with 36% of world export value, ahead of Australia (16%), Indonesia (8.1%), Senegal (6.8%) and Mozambique (6.6%), on world trade of $1.7 billion (CEPII BACI). China was the largest importer with 48% of import value, followed by India (9.9%), Spain (9.3%) and Malaysia (4.9%). USGS also names Australia and South Africa as the leading exporters and China as the leading importer.

The export ranking differs from the mining ranking. Australia mines the most but ranks second on export value (16%), while South Africa leads exports with 36% against a mining share of 23%. Mozambique is the third-largest miner but fifth on export value (6.6%). China mines 8.3% of the world's concentrate but is only fourteenth on export value (1%), and is by far the largest importer. The customs line records only what customs declare as zirconium ore or concentrate. USGS applies a similar boundary in its own United States export figures, which exclude zircon contained in mixed mineral concentrates. Export shares here are by value for 2024, while mining shares are by tonnes for 2025. By export tonnes, Mozambique ranks second, against fifth by value.

USGS lists South Africa, Australia and Senegal as the leading sources of United States ore imports, and puts the US tariff on zirconium ores and concentrates at zero (normal trade relations rate, 31 December 2025). HS 261510 does not cover zirconium chemicals, metal, ferrozirconium or hafnium, which have their own codes, so the table says nothing about those stages. See producing, exporting and processing and HS codes for how to read such tables.

This page quotes no zircon price. There is no free public spot-price benchmark for zircon. USGS publishes annual averages, and producers such as Iluka publish quarterly realised prices in free reviews, but none is a daily or weekly series, so this site does not chart one. USGS draws its zircon prices from a private source, Fastmarkets IM, which it cites for premium-grade zircon on a cost, insurance and freight (CIF) basis into China, in dollars per metric ton of gross weight. USGS adds the unit value of United States imports from Australia, Senegal and South Africa, landed and duty-paid. Zirconium sponge, quoted ex-works China per kilogram, and unwrought hafnium come from Argus Media annual averages.

What can be said is how the market works. Zircon is sold in different grades and forms, and prices are not interchangeable. In its review to 30 September 2025, Iluka reported a weighted average realised price across premium and standard zircon, and said the prices for each product, including zircon in concentrate, vary. A figure called "the zircon price" therefore depends on grade, delivery point (CIF China is a different basis from a landed price, see CIF and FOB) and sales mix. Iluka also said competitors had again reduced prices in China after weaker domestic zircon sand pricing derived from imported concentrates, and that customers were cautious about holding inventory. That is one producer's account as of 17 October 2025, and this page says nothing about later prices.

USGS names ceramics as the leading end use of zircon in the United States. In its review to 30 September 2025, Iluka said global ceramic tile production and consumption had continued to decline in 2025, led by China, where it cited persistent weakness in the real estate sector and oversupply in the domestic tile industry.

Zircon is recovered alongside ilmenite and rutile, so a mine's zircon output follows decisions made for titanium feedstock. Iluka announced on 10 September 2025 that production at its Cataby mine and SR2 synthetic rutile plant would be suspended from 1 December 2025, for about 12 and 6 months respectively. In its 17 October 2025 review it gave the reasons as subdued market demand and the current levels of synthetic rutile inventory, and described the pigment market as weak. The suspension took effect, and Iluka's January 2026 outlook assumed both stayed idle throughout 2026. A change in the market for the titanium products can therefore change zircon supply without any change in zircon demand.

PYX Resources, an Australia-based company listed on the NSX with a London secondary listing and zircon mines in Central Kalimantan, Indonesia, reported in September 2025 that its RKAB (Work Plan and Budget) production approvals were suspended. It said the suspension applied to all zircon producers in Central Kalimantan (14 companies were notified) and attributed it to government statements about addressing oversupply across several sectors. PYX said the government would resume issuing RKAB from 2026; this page has not verified the current status. Iluka's 17 October 2025 review separately mentions zircon production halts in Indonesia. The USGS table shows lower estimated Indonesian output in 2025 than in 2024, and this page does not claim the two are linked.

Rio Tinto declared force majeure on customer contracts at Richards Bay Minerals in South Africa on 30 June 2021 after a deterioration in security around the mine, restarted operations in August 2021 and lifted force majeure in March 2022.

USGS reports that several companies continued exploration and development of projects planned to produce zircon concentrates in Australia, Mozambique, South Africa, Sri Lanka, Tanzania and elsewhere. This page does not forecast when any of them will add supply.

Zirconium metal for nuclear fuel cladding needs hafnium removed first. USGS says one producer in Oregon and one in Utah make zirconium and hafnium metal from chemical intermediates, and it lists hafnium's leading use as superalloys. USGS gives no end-use shares.

USGS says chromite and olivine can replace zircon in some foundry uses, and dolomite and spinel refractories in some high-temperature uses. It adds that zircon foundry cores and spent zirconia refractories are often recycled but cannot be quantified.

Heavy-mineral sands are mined by two main methods. Iluka describes dry mining with scrapers and other heavy machinery, and wet mining with a dredge, which the industry uses typically where the ore sits below the water table. Iluka's 2009 technical brochure says its own operations use dry mining. The valuable minerals are a small part of the material moved. A wet concentrator washes the ore through spiral separators that use gravity to separate the heavy minerals from lighter quartz and clay, giving a heavy-mineral concentrate.

That concentrate goes to a dry plant, where Iluka lists rare earth magnets, electrostatic separation and air tables among the steps that split ilmenite, rutile and zircon from each other. ZIA says the final zircon concentrate typically contains about 65 percent combined zirconium and hafnium oxide. ZIA lists zircon sand, flour, opacifier, fused zirconia, zirconium chemicals and zirconium metal as the main forms and conversion routes.

Metal is a longer path. A Westinghouse patent describes the traditional route: zirconium oxide contaminated with hafnium oxide is chlorinated to a mixture of tetrachlorides, which is dissolved in acid and separated in a liquid-liquid extraction with organic solvents, and the separated zirconium is then reduced to metal with magnesium in the Kroll process. Hafnium therefore comes out at the chloride stage, before reduction. Wikipedia's zirconium article adds that commercial zirconium typically contains a small proportion of hafnium, which absorbs neutrons strongly and must be removed for nuclear use. A Y-12 history describes hafnium being separated from zirconium at Oak Ridge from the early 1950s, in a highly corrosive chemical process, to supply the pure zirconium for naval reactor fuel cladding. USGS says the metal is produced from zirconium chemical intermediates by one producer in Oregon and one in Utah.

Units therefore change along the chain: concentrate in gross tonnes, reserves as ZrO2 content, and sponge and hafnium priced per kilogram.

USGS gives ceramics as the leading end use of zircon in the United States, with foundry sand, refractories and zirconium chemicals as other primary uses. It does not publish a split of world use in percentages, and this page does not give one.

Ceramics. Tronox, in its 2025 annual report, says zircon is added to ceramic glazes to make them more resistant to water, chemicals and abrasion.

Foundry sand and refractories. Zircon is used as molding sand when high-quality castings are needed. According to Tronox, zircon refractories are expensive and used only where wear and corrosion are demanding, in the glass, steel and cement industries.

Chemicals and metal. Zirconium chemicals and zirconium metal are made from zircon, and Tronox also lists zircon in television screen glass. The metal is used for nuclear fuel cladding. The Nautilus, commissioned in 1954 as the US Navy's first nuclear-powered ship, ran on zirconium-clad fuel according to Y-12.

Hafnium. USGS lists superalloys as hafnium metal's leading use. It adds that boron or cadmium-silver-indium alloys can replace hafnium in nuclear control rods, and that niobium, stainless steel and tantalum provide some substitution in nuclear applications of zirconium.

The chain runs from sand deposit to heavy-mineral concentrate, to separated zircon, and from zircon either directly into tiles, castings and refractories or through chemical plants into zirconia, chemicals and metal. Mining is concentrated: 69% of output comes from three countries. Buying is concentrated differently. China takes 48% of import value in the ore line, while South Africa leads on export value (36%), so one large importing country is supplied by several exporting ones.

Zirconium is on the US critical minerals list. USGS announced its final 2025 list (60 minerals) on 6 November 2025 and published it in the Federal Register on 7 November 2025, and the Congressional Research Service reports that zirconium was included on the second of USGS's two tests, whether supply relied on a sole domestic producer representing a single point of failure. That test concerns the US supply chain. The EU's list of 34 critical raw materials under the Critical Raw Materials Act (Regulation (EU) 2024/1252) includes hafnium but not zirconium, according to the Commission's raw materials information system. The critical minerals hub explains what the lists are, and the glossary entry defines the term.

Because zircon comes with titanium minerals, the page for titanium is the closest companion, and tin and rare earths are listed as related commodities. Much of the chain sits outside mining: ceramics makers, foundries, refractory makers and chemical plants are the customers for zircon, and USGS says the United States was a net exporter of zirconium metal.
