Molybdenum comes mainly from China, which produced 97,000 tonnes in 2025, 37% of the world's 260,000 tonnes (USGS MCS). Chile (16%), United States (15%) and Peru (15%) follow; the top five together supply 90%. The biggest exporter of molybdenum ore (HS 2613) is Chile (24% of world export value in 2024, CEPII BACI). Molybdenum concentrates in the same porphyry systems that host copper, so most of it is mined incidentally in Chile, Peru and the American west, with only a handful of deposits rich enough to be worth mining for molybdenum alone.

*A refractory metal recovered mostly as a by-product of copper mining, added to steel for strength and corrosion resistance.* Also called: Mo, moly, molybdenite, ferromolybdenum.

In 2025 China mined 97,000 tonnes of molybdenum content, 37% of the world's 260,000 tonnes (USGS MCS). Chile followed with 16%, then United States (15%), Peru (15%) and Mexico (6.5%). The top five account for 90% and 15 countries mine it. Reserves stand at 17 million tonnes, with China holding 46% (USGS MCS).

The important distinction in this market is between by-product and primary supply. Most molybdenum comes out of copper porphyry mines in Chile, Peru, Mexico and the United States, where molybdenite is recovered from the copper flotation circuit as a credit against copper's costs. A minority comes from primary molybdenum mines, principally in Colorado and in China, which exist because their ore is rich enough to justify mining molybdenum on its own.

That split determines how the market behaves. By-product supply is set by copper mining decisions and barely responds to the molybdenum price: a copper mine keeps producing molybdenum at any price because the copper pays the bills. Primary mines are the swing supply, and they open and close with the price, which is why Colorado operations have been placed on care and maintenance and restarted repeatedly over the decades.

World output changed +2% on the previous year. Because supply follows copper, the best single predictor of molybdenum availability is what is happening on the copper page rather than anything in the molybdenum market itself.

## Who exports and imports molybdenum?

Because most molybdenum comes out of copper mines, its supply responds to the copper price rather than its own.

Chile was the largest exporter of molybdenum ore (HS 2613) in 2024 with 24% of world export value, ahead of Peru (19%), on world trade of $8.2 billion (CEPII BACI). South Korea was the largest importer with 13%.

The trade runs from mines to roasters to steel mills, and the roasting step is where the geography changes. Molybdenite concentrate must be roasted to technical molybdic oxide before it can be used, and roasting capacity sits in Chile, the United States, Europe and China rather than necessarily at the mine. Sulphur dioxide emission controls have closed roasters in some jurisdictions and concentrated the step in others, so concentrate and oxide follow different routes.

## What does molybdenum cost?

### How it is priced

This page quotes no molybdenum price, because there is no free public series. Molybdenum oxide is assessed by private price reporting agencies in dollars per pound of contained molybdenum, with separate assessments for concentrate, technical oxide and ferromolybdenum, and the London Metal Exchange contract that exists is thin and settles against those assessments. Publishing a number would require a license this site does not hold.

What can be said is how the market works. Producers sell concentrate to roasters or convert it themselves; steel mills buy either technical oxide in briquettes or ferromolybdenum, and they buy on monthly or quarterly formulas referencing the published assessments. Because molybdenum is used in small percentages, a few tenths of a percent up to several percent in specialty grades, a mill's molybdenum cost is small relative to its total input bill, which makes demand relatively insensitive to price in the short run.

The market is also unusually volatile for a metal of its size, and the reason is the by-product structure. When demand rises, by-product supply cannot respond, primary mines take a year or more to restart, and the price can multiply. When demand falls, by-product supply keeps arriving regardless, and the price collapses. That asymmetry has produced some of the sharpest price cycles in the metals complex, and it is the single most useful thing to know about molybdenum.

## What moves the price of molybdenum?

### Copper mining output

Because most molybdenum is a copper by-product, molybdenum supply is decided by copper investment and copper ore grades. A wave of copper expansion delivers molybdenum whether or not it is wanted, and a copper mine's decision to skip its molybdenum circuit for grade reasons removes supply silently.

### Oil and gas drilling

Molybdenum's largest specialty use is in the alloy steels used for line pipe, drill pipe, pressure vessels and refinery equipment. Upstream oil and gas capital spending therefore drives a meaningful share of demand, and pipeline projects in particular consume large tonnages of molybdenum-bearing steel.

### Stainless and specialty steel production

Molybdenum improves corrosion resistance, especially against chlorides, and is essential to the 316 grade stainless used in chemical plant, desalination and marine applications. Demand therefore follows the same industrial investment cycle described on the chromium page.

### Primary mine restarts

Colorado and Chinese primary mines are the swing supply. Their restart decisions require sustained high prices and take a year or more to deliver metal, which is why price spikes persist longer in molybdenum than in metals with responsive supply.

### Chinese production and export policy

China is both a large producer and a large consumer, and its export taxes, quotas and environmental enforcement against small roasters have periodically swung the balance between domestic and world availability.

### Roasting capacity and emission rules

Roasting molybdenite releases sulfur dioxide, and tightening emission standards have closed roasters in several countries. Because concentrate cannot be used until it is roasted, a shortage of compliant roasting capacity can create a bottleneck between mine and mill.

### Scrap and recycling

Molybdenum is recovered from stainless and alloy steel scrap and from spent petroleum refining catalysts, which are unusually rich in it. Recycling supplies a meaningful minority of consumption and rises with price, partially damping cycles.

## How is molybdenum produced?

In a copper porphyry mine, molybdenite occurs alongside copper sulfides and is separated from them in a dedicated flotation circuit after the bulk copper-molybdenum concentrate has been made. The separation exploits small differences in surface chemistry and typically uses a depressant to hold back the copper minerals while the molybdenite floats. The resulting concentrate is roughly fifty percent molybdenum.

At a primary mine the ore is mined by open pit or block caving, ground, and floated directly for molybdenite without a copper circuit. Grades are low, often a fraction of a percent, so the operations are large-tonnage earth-moving businesses.

The concentrate is then roasted in multiple-hearth furnaces at around six hundred degrees, driving off sulfur as sulfur dioxide and converting molybdenite to technical molybdic oxide. That sulfur dioxide is captured for acid production where regulations require, which is a significant part of the roaster's cost. The oxide is sold in briquettes to steel mills, converted to ferromolybdenum by aluminothermic reduction for direct addition to steel, or purified further into chemical-grade products.

Everything on this page is contained molybdenum. A tonne of concentrate is roughly half a tonne of metal, and prices are quoted per pound of contained metal rather than per pound of material, so comparisons require care.

## What is molybdenum used for?

Steel takes the large majority. Molybdenum raises hardenability, strength at high temperature and resistance to corrosion and creep, so it appears in construction and engineering steels, in the pipeline and pressure-vessel steels used by the oil, gas and power industries, and in the tool and high-speed steels used for cutting.

Stainless steel is the second large use, particularly the molybdenum-bearing grades that resist chloride pitting: 316 stainless in chemical plant, food processing, desalination and marine hardware, and the duplex and super-duplex grades used offshore.

Superalloys for turbine and aerospace components use molybdenum for high-temperature strength. Pure molybdenum metal, which has a very high melting point and low thermal expansion, is used for furnace elements, glass-melting electrodes, semiconductor substrates and X-ray tube targets.

The chemical uses are small in tonnage and large in importance. Molybdenum disulfide is a solid lubricant that works where oils fail, and molybdenum catalysts are essential to hydrodesulfurization, the refinery process that removes sulfur from fuels. Tightening fuel sulfur limits worldwide have made that catalyst market a steady source of demand, and spent catalysts are a valuable recycling stream.

## Supply chain and chokepoints

The chain runs mine, flotation, roaster, steel mill, and its distinctive feature is that the first step is controlled by an entirely different industry. Molybdenum availability depends on copper miners' decisions about ore grade, throughput and whether to operate their molybdenum circuit at all, and those decisions are made on copper economics.

The roasting step is the genuine physical bottleneck. It requires specialized furnaces and sulfur dioxide capture, permits are difficult in tightly regulated jurisdictions, and the capacity is concentrated in a limited number of plants. A roaster outage strands concentrate that cannot otherwise be used.

Physical logistics are undemanding: concentrate and oxide move in drums, bags and containers in modest tonnages, and the whole world market would fit in a small number of ships. There is no meaningful freight constraint.

The vulnerability is price volatility rather than physical scarcity. Reserves are large relative to consumption and spread across several countries, but the inelastic by-product supply structure means that the market swings violently between shortage and glut, and that volatility discourages the primary mine investment that would stabilize it. Buyers manage this with formula pricing and inventory rather than by finding alternative sources, because for the corrosion and high-temperature jobs molybdenum does, substitutes generally perform worse.

## Timeline

- 1918: Climax in Colorado begins production. The discovery and development of an exceptionally rich primary deposit created the world's swing supplier and the reference point for molybdenum supply for most of the twentieth century. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 1930s: Molybdenum becomes standard in alloy steels. Recognition that small additions improved hardenability and high-temperature strength made molybdenum a routine steel additive rather than a specialty, establishing its main market. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 1980s: Copper by-product supply overtakes primary mining. Expansion of Chilean and American porphyry copper mining made molybdenum predominantly a by-product, permanently changing how its supply responds to price. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 1995: Climax is placed on care and maintenance. Low prices closed the archetypal primary mine, demonstrating the asymmetry of a market where by-product supply continues regardless and primary supply is the only thing that can leave. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 2005-06: Molybdenum prices reach an extraordinary peak. Chinese steel demand met inelastic by-product supply and prices rose by an order of magnitude within two years, prompting a wave of primary mine restarts and expansions. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 2006: China introduces export restrictions. Export taxes and quotas on molybdenum products tightened world availability and encouraged capacity investment elsewhere, a pattern later repeated across several critical minerals. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 2012-05: Climax restarts after a seventeen-year closure. Sustained higher prices justified reopening the primary mine, adding swing capacity back to the market just as the Chinese steel cycle was turning. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 2016-01: A price collapse follows the commodity downturn. Weak steel and oilfield demand met undiminished copper by-product supply, and the price fell to levels that again closed primary capacity. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 2023-02: Prices spike on low copper by-product output. Falling ore grades and operational problems at major copper mines cut molybdenum output while pipeline and refinery demand held, and the price rose sharply without any change in molybdenum-specific fundamentals. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)

## Frequently asked questions

### which country produces the most molybdenum

China mined 97,000 tonnes of molybdenum content in 2025, 37% of the world's 260,000 tonnes (USGS MCS). Chile was second with 16%. Most of it comes out of copper porphyry mines as a by-product.

### what is molybdenum used for

Mainly as an additive to steel, where it raises hardenability, high-temperature strength and corrosion resistance. It is essential to 316 stainless and to pipeline and pressure-vessel steels, and it appears in superalloys, furnace components, solid lubricants and the catalysts that remove sulfur from fuels.

### why is there no molybdenum price on this page

No free public series exists. Molybdenum oxide, concentrate and ferromolybdenum are assessed by private price reporting agencies in dollars per pound of contained metal, and the exchange contract that exists settles against those assessments rather than providing an independent public benchmark.

### why are molybdenum prices so volatile

Because most supply is a copper by-product that continues regardless of the molybdenum price, while primary mines take a year or more to restart. Demand shifts therefore hit an unresponsive supply base, producing multiplied price moves in both directions.

### how much molybdenum is left

World reserves are 17 million tonnes, with China holding 46% (USGS MCS). Reserves are large relative to annual consumption, so the constraint in this market is the responsiveness of supply rather than the quantity of ore.

### is molybdenum recycled

Yes, from stainless and alloy steel scrap and from spent petroleum refining catalysts, which are unusually rich in it. Recycling supplies a meaningful minority of consumption and increases when prices rise, which partly damps the market's severe cycles.
