Bauxite comes mainly from Guinea, which produced 150 million tonnes in 2025, 34% of the world's 440 million tonnes (USGS MCS). Australia (22%), China (20%) and Brazil (7.5%) follow; the top five together supply 89%. The biggest exporter of bauxite (HS 2606) is Guinea (72% of world export value in 2024, CEPII BACI). Bauxite is a tropical weathering product: it forms where heavy rain and heat leached everything soluble out of ancient land surfaces over millions of years, leaving aluminium oxides behind, which is why the deposits ring the tropics from Guinea to Australia to the Caribbean.

*The ore of aluminum: a tropical weathering product refined into alumina, which is then smelted into metal.* Also called: bauxite ore, alumina, aluminium ore, aluminum ore, gibbsite.

In 2025 Guinea mined 150 million tonnes of bauxite, 34% of the world's 440 million tonnes (USGS MCS). Australia followed with 22%, then China (20%), Brazil (7.5%) and India (5.7%). The top five account for 89%. Reserves are held mainly in the same places: Guinea holds 26% of the world's 29 billion tonnes (USGS MCS).

The second step in the chain has a different map. Alumina refining, which converts bauxite into the white powder that smelters actually feed, came to {{prod.Alumina, refinery production.world}} in 2025, led by {{prod.Alumina, refinery production.top1.name}} with {{prod.Alumina, refinery production.top1.share}} (USGS MCS). Refining happens either at the mine, where a country has both bauxite and energy, or next to the smelters, and the split explains most of the trade described below.

The geology is unusually legible. Bauxite needs a stable land surface, high rainfall and warmth over geological time, so it occurs as blankets over old plateaux: the Boké region of Guinea, the Weipa and Darling Range deposits of Australia, the Trombetas area of Brazil, the Jamaican and Guyanese deposits, and karst bauxites around the Mediterranean and in China and Vietnam. Guinea's are among the largest and highest grade on earth and sit close to the coast.

Three units are used loosely in this industry and confusing them is easy. Roughly four tonnes of bauxite make two tonnes of alumina, which make one tonne of aluminium metal. Figures on this page are dry tonnes of bauxite unless the alumina item is named explicitly.

## Who exports and imports bauxite?

Guinea ships raw bauxite; Australia ships both bauxite and alumina; China imports bauxite and refines alumina at home for its smelters.

Guinea was the largest exporter of bauxite (HS 2606) in 2024 with 72% of world export value, ahead of Australia (16%), on world trade of $11.5 billion (CEPII BACI). China was the largest importer with 86%.

That is the defining relationship in the modern bauxite market: Guinea digs, China refines. Chinese alumina refineries expanded far beyond what domestic bauxite could support, and Guinea, with large high-grade deposits near the coast and no domestic refining industry of consequence, filled the gap. Australia exports both bauxite and alumina; Indonesia and Malaysia have repeatedly banned or restricted raw ore exports to force refining at home, with mixed results. Read the export table as a story about which countries chose to ship rock and which chose to ship powder.

## What does bauxite cost?

### How it is priced

This page quotes no bauxite or alumina price, and the reason is straightforward: neither has a free public benchmark series. Bauxite is largely moved under long-term contracts between affiliated companies or on privately assessed spot terms delivered to Chinese ports, priced by alumina content, reactive silica and moisture. Alumina is more liquid, with several private indices assessing free-on-board Australia and delivered China, and there are exchange contracts settling against those indices, but the assessments themselves are licensed.

What can be said is how alumina and metal prices relate, and it is a useful rule. Alumina has historically contracted at a percentage of the London Metal Exchange aluminium price, typically somewhere in the mid to high teens, and although index-linked pricing has largely replaced that formula, the relationship still anchors expectations. That is why the aluminium page's price series is the best available guide to what is happening upstream: when the metal price moves, alumina follows, and bauxite follows alumina at a distance.

Bauxite's own economics are dominated by freight and by quality. The rock is low value per tonne and travels in capesize bulk carriers, so a change in freight rates can move the delivered cost by a large percentage. Quality is priced on available alumina and on reactive silica, which consumes caustic soda in the refinery and is therefore a direct cost penalty. A high-silica bauxite can be worth less than half a low-silica one of the same alumina grade.

## What moves the price of bauxite?

### Chinese alumina refinery demand

Chinese refining capacity exceeds what domestic bauxite can supply, so Chinese import demand is the single largest force in the seaborne bauxite market. Refinery utilization, driven by aluminium smelter margins and by provincial power policy, therefore sets bauxite demand more than mining decisions do.

### Export bans and resource nationalism

Indonesia banned bauxite exports in 2014, partially relaxed and then re-imposed restrictions, and Malaysia has suspended mining on environmental grounds. Each move removed a supplier at short notice and redirected demand, most consistently toward Guinea. Policy has moved this market more than geology has.

### Guinean political and logistical risk

A large share of seaborne bauxite now comes from one country with limited infrastructure, where mining depends on rail, barge and transhipment operations and where political instability has previously interrupted exports. Concentration of supply in a single origin is the market's main vulnerability.

### Caustic soda and energy costs at refineries

The Bayer process consumes caustic soda and a great deal of heat. When caustic or energy prices rise, refining margins compress and refineries cut runs, reducing bauxite demand even when aluminium demand is unchanged.

### Reactive silica and ore quality

Silica in bauxite reacts with caustic soda and is lost, so refineries pay a penalty for it. Deposits with low reactive silica command a premium, and the quality mix available in the market shifts effective prices independently of headline supply and demand.

### Freight rates

Bauxite is among the lowest-value cargoes moved in bulk, so ocean freight is a large share of delivered cost. Rising capesize rates lengthen the effective distance to market and favor suppliers closer to the refineries.

### Aluminium demand and smelter power

Everything upstream is ultimately driven by aluminium, and aluminium smelting is set by electricity availability. Power rationing in China's Yunnan province or European smelter closures on high gas prices propagate back up the chain to alumina and then to bauxite within months.

## How is bauxite produced?

Bauxite is mined almost entirely by open pit, usually by stripping a shallow overburden and digging a blanket deposit a few meters thick. Little beneficiation is done: the ore may be crushed, washed to remove clay and screened, and it is then railed or trucked to a port. Because the deposits are shallow and soft, mining costs are low and the operation is essentially a large earthmoving exercise.

Refining uses the Bayer process, unchanged in principle since 1888. Ground bauxite is digested in hot caustic soda under pressure, which dissolves the aluminium hydroxide minerals and leaves the iron and silicate impurities as a red slurry. That residue, red mud, is separated and impounded, and it is the industry's largest environmental liability: it is highly alkaline and produced in enormous volumes, roughly one to two tonnes for every tonne of alumina. The clarified liquor is cooled and seeded so that aluminium hydroxide crystallizes out, and the crystals are calcined at around a thousand degrees to drive off water, leaving alumina.

Smelting, described on the aluminium page, then dissolves alumina in molten cryolite and passes an enormous electric current through it to strip the oxygen away, leaving metal. That is where the electricity goes: refining is energy-intensive, but smelting is in a different class entirely.

The reason the chain is split across countries is that each step has a different optimal location. Mining wants to be at the deposit, refining wants cheap heat and proximity to either the mine or the smelter, and smelting wants the cheapest electricity on earth.

## What is bauxite used for?

Almost all bauxite becomes alumina, and almost all alumina becomes aluminium metal. The metal's uses are described on the aluminium page: transport, packaging, construction, electrical transmission and consumer goods.

The minority that does not go to smelters is called non-metallurgical or specialty alumina, and it is a high-value business in its own right. Calcined alumina is used in refractories, ceramics, abrasives and spark plug insulators. Alumina is the substrate for catalysts and the carrier in water treatment. Fused alumina makes grinding wheels and sandpaper. Tabular alumina lines furnaces. Aluminium hydroxide is used as a flame retardant filler in plastics and in antacids.

Bauxite that does not go to refineries at all is used directly: calcined bauxite makes high-alumina refractory bricks, provides skid-resistant road surfacing aggregate, and is used as a proppant in oil and gas wells. These uses take a small share of world output but sell at higher prices than metallurgical grade.

## Supply chain and chokepoints

The chain is mine, refinery, smelter, and it has been deliberately unbundled across countries in a way that concentrates risk at each handoff. Guinea to China is now the single largest bauxite flow in the world, and it depends on a small number of mining operations, a rail and barge system, offshore transhipment because the ports are shallow, and a long capesize voyage. Any of those can fail, and political instability in Guinea has already interrupted the flow once.

Red mud is the chain's quiet liability. Refineries accumulate vast impoundments of alkaline residue, and a dam failure is catastrophic, as Hungary demonstrated in 2010. Permitting new refining capacity anywhere with strong environmental regulation now turns substantially on residue management, which is one reason refining has concentrated where it has.

Alumina shipping is a straightforward bulk trade with a real chokepoint at the smelter end: a smelter cannot stop. Interrupting the power or the alumina feed to a potline for more than a few hours freezes the electrolytic bath and can destroy the cells, requiring an expensive rebuild. Alumina supply security is therefore treated as an operational imperative rather than a commercial matter, and smelters hold inventory accordingly.

The structural risk is the same one that runs through several pages on this site: abundant resource, concentrated processing. Bauxite reserves are large and spread across many tropical countries, but the refining capacity that turns rock into feedstock, and the cheap power that turns feedstock into metal, are not.

## Timeline

- 1821: Bauxite is identified at Les Baux in France. The rock that gave the mineral its name was recognized as an aluminium ore, though extracting the metal remained prohibitively expensive for another sixty years. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 1888: Bayer patents the alumina refining process. Digesting bauxite in caustic soda to precipitate pure aluminium hydroxide made alumina cheap and, combined with electrolytic smelting, turned aluminium from a precious metal into a commodity. (https://international-aluminium.org)
- 1963: Weipa in Queensland begins production. A very large, high-grade deposit close to the coast established Australia as the dominant bauxite exporter for the following half century. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 1974-03: The International Bauxite Association is formed. Jamaica and other producers created a producer association and raised levies after the oil crisis, the closest bauxite has come to a cartel and a spur to Australian and Guinean development. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 2010-10: The Ajka red mud dam fails in Hungary. A residue impoundment collapse killed ten people and contaminated a river system, and refinery residue management became a central permitting question worldwide. (https://www.eea.europa.eu/)
- 2014-01: Indonesia bans raw bauxite exports. A ban intended to force domestic refining removed a major supplier overnight, sent prices up sharply and redirected Chinese buying decisively toward Guinea. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 2016-01: Malaysia suspends bauxite mining. Environmental damage from unregulated mining in Pahang led to a moratorium, removing the supplier that had partly replaced Indonesia and tightening the market again. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 2018-04: Sanctions on a major producer disrupt alumina supply. Restrictions on Rusal, combined with a production cut at a large Brazilian refinery, sent alumina prices to record levels and showed how tightly the metal price depends on the refining step. (https://data.imf.org/en/datasets/IMF.RES:PCPS)
- 2021-09: Political instability in Guinea threatens the largest flow. A coup in the country supplying the biggest share of seaborne bauxite lifted aluminium prices immediately, illustrating the concentration risk in the chain. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)
- 2023-06: Guinea overtakes Australia in seaborne supply. Sustained expansion of Boké-region mining made Guinea the largest bauxite exporter, completing a shift in the market's centre of gravity that began with Indonesia's ban. (https://www.usgs.gov/centers/national-minerals-information-center/mineral-commodity-summaries)

## Frequently asked questions

### which country produces the most bauxite

Guinea mined 150 million tonnes in 2025, 34% of the world's 440 million tonnes (USGS MCS). Australia was second with 22%. Alumina refining has a different map: {{prod.Alumina, refinery production.top1.name}} led with {{prod.Alumina, refinery production.top1.share}} of {{prod.Alumina, refinery production.world}}.

### what is bauxite used for

Almost all of it is refined into alumina and then smelted into aluminium metal. A minority becomes specialty alumina for refractories, ceramics, abrasives, catalysts and flame retardants, or is used directly as calcined bauxite in refractory bricks, road surfacing and oilfield proppants.

### how much bauxite makes a tonne of aluminium

Roughly four tonnes of bauxite yield two tonnes of alumina, which yield one tonne of aluminium metal. Confusing the three units is the most common error in reading aluminium industry figures, so this page states dry tonnes of bauxite unless the alumina item is named.

### why is there no bauxite price here

Neither bauxite nor alumina has a free public benchmark. Bauxite moves on long-term or privately assessed contracts priced by alumina content and reactive silica; alumina is assessed by private indices. Alumina has historically contracted at a percentage of the aluminium price, so the aluminium page is the best available guide.

### why does Guinea export so much bauxite

It has some of the largest and highest-grade deposits on earth, close to the coast, and no significant domestic refining industry. When Indonesia banned raw ore exports in 2014 and Malaysia suspended mining in 2016, Chinese refineries turned to Guinea, and it has since become the largest seaborne supplier.

### what is red mud

The alkaline residue left after the Bayer process dissolves aluminium out of bauxite, produced at roughly one to two tonnes per tonne of alumina. It is impounded behind dams, and a failure at Ajka in Hungary in 2010 killed ten people, making residue management a central issue in permitting new refineries.

### how much bauxite is left

Guinea holds 26% of world bauxite reserves of 29 billion tonnes (USGS MCS). Reserves are large relative to demand and spread across many tropical countries, so the constraint in this chain is refining and smelting capacity rather than ore.
