Top Copper Mining Companies
Global Rankings

The distinction is not academic. Escondida produced about 1.28 million tonnes of copper in 2024. BHP owns 57.5% of it. Attributable accounting gives BHP around 714,000 tonnes from Escondida. Rio Tinto gets credited with 30%, JECO takes 12.5%. Under consolidated accounting the full 1.28 million tonnes goes on BHP's books. Codelco, state-owned, holds full or near-full control of its mines, so both frameworks produce roughly the same number for them. Any ranking that names a definitive number one has already picked a side on this question.

Codelco gets a disproportionate amount of space here because the gap between its ranking position and its underlying condition is wider than for any other company on the list.

Debt-to-EBITDA around six times. Moody's cut the rating in May 2025. All four structural expansion projects over budget and behind schedule. The company set a 2026 production target of 1.344 million tonnes, barely 0.7% above 2025. Juan Ignacio Guzmán of GEM mineral consulting told Reuters, in comments published in March 2026, that Codelco's project execution is far from competitive and that non-market practices lead to dressed-up numbers.

Reuters also reported seeing an internal Codelco production document showing Chuquicamata's oxide section producing 25,000 tonnes in December 2025 against a plan of 4,000 tonnes. A single month hitting six times its own target is not how stable operations look.

El Teniente, the world's largest underground copper mine, suffered a collapse from a 4.2-magnitude earthquake in July 2025. Six workers killed. Judicial investigation opened. Some underground sections remain closed. The mine produced around 172,000 tonnes in the first half of 2025 and the collapse is estimated to have cost 20,000 to 30,000 tonnes. Codelco's November 2025 announcement lowered 2025 guidance from 1.34-1.37 million tonnes to 1.31-1.34 million.

Freeport-McMoRan produced about 3.5 billion pounds of copper in 2025. Grasberg contributed around 816,000 tonnes in 2024, 8.4% above the prior year.

Every ranking calls Grasberg a copper mine. It is also one of the planet's largest gold deposits and that second identity changes how Freeport's economics work in ways the rankings do not reflect. Gold by-product revenue pushes Freeport's net cash cost per pound of copper well below most competitors. Looking at Freeport's cost position without isolating the gold credit gives you a misleading picture. At four dollars a pound for copper, Freeport was making outsized margins, and a meaningful share of that comes from gold rather than copper mining efficiency.

About 800,000 tonnes of wet material flooded the Block Cave workings in September 2024. Seven workers died. Freeport has said the phased restart begins Q2 2026, full recovery maybe 2027. Goldman Sachs flagged the shutdown, in analysis covered by MINING.COM in October 2025, as a potential trigger for global copper supply deficit. Freeport's US operations are 70% of domestically refined copper, which gives the Grasberg situation a second dimension beyond global concentrate supply.

On leaching technology improvements, Freeport says these could add around 800 million pounds of annual capacity by 2030 without building anything new.

BHP built a desalination plant for Escondida in 2018 that cost 3.43 billion dollars. Two 170-kilometer pipelines, 42 inches diameter, four pumping stations, lifting desalinated seawater from the Pacific coast to 3,200 meters elevation. Largest desalination plant in the Americas when it was finished.

To put 3.43 billion in context, that is more than most new copper mines cost to build entirely. The whole mine. BHP spent that much just on water for one existing operation.

Escondida sits in the Atacama Desert where parts have never recorded rainfall. Chile's environmental regulator charged in 2020 that the mine had exceeded its water extraction permits for close to 15 years, with groundwater levels dropping to triple the allowed 25-centimeter decline threshold. The First Environmental Court of Antofagasta imposed over 8 million dollars in compensation in 2024. BHP has publicly committed to ending all freshwater use in Chile by 2030. Cochilco projects seawater will reach roughly 43% of Chilean mining water consumption within the decade.

Grade decline connects to this. Lower grades mean more tonnes of rock processed for the same copper output, and more rock means more water consumed. Both curves are moving in the wrong direction simultaneously.

The mine's origin story is worth including. On March 14, 1981, the last scheduled borehole in an exploration program, designated Pozo 6, hit 52 meters at 1.51% copper at 240 meters depth. "Escondida" is Spanish for "hidden" because the ore body has no surface expression, buried under hundreds of meters of barren cover. One fewer borehole in the budget and the discovery does not happen. By 2007 the mine was producing 1.483 million tonnes of copper worth 10.12 billion dollars, 4.3% of Chile's GDP, about 15% of exports. Direct costs ran 60.8 cents a pound against an average price of 3.23 dollars. Tax payments that year hit 2.2 billion. Workers struck for 25 days demanding a 13% raise and a 30,000-dollar bonus, settled for 5% and 17,000. CUT chairman Arturo Martínez said during the strike that the situation put copper renationalization back on Chile's agenda.

Almost every article ranking copper mining companies leaves this out. It changes the meaning of those rankings more than any single mine's output does.

TC/RC, Treatment Charge and Refining Charge, is the fee miners pay smelters for turning concentrate into refined copper. More concentrate than smelter capacity means smelters charge higher fees. Tight concentrate means smelters compete for feed and fees drop. That mechanism has structured copper industry economics for decades and it broke.

The annual benchmark for 2026, negotiated between Antofagasta and Chinese smelters, came in at zero dollars per tonne. The IEA reported this in their analysis published early 2026 and called it the lowest level ever agreed. The spot market had already gone further. Fastmarkets' weekly assessment of the spot TC index reached negative 66.60 dollars per tonne in October 2025. Negative 45 back in May. Smelters paying miners to accept concentrate. The entire fee relationship flipped.

Outside China the damage is visible. JX Advanced Metals in Japan cut production by tens of thousands of tonnes. Mitsubishi Materials described conditions as severely deteriorated. Glencore got emergency government money to keep Mount Isa in Australia running for another three years. Japan, South Korea, and Spain put out a joint ministerial statement criticizing TC/RC levels. Aurubis in Europe pushed recycling to 45% of its production and built a recycling smelter in the US to reduce its exposure. All of this from the Crux Investor and Fastmarkets reporting around the FT metals conference in October 2025. Nyrstar's CEO Guido Janssen, at the same conference, called what China was doing a kind of reverse dumping: buying concentrate volume and extracting value from critical by-product metals within it.

CSPT announced a 10% production cut for 2026. CRU's analysis puts the resulting capacity reduction at about 961,000 tonnes, which on paper covers the projected 834,000-tonne global concentrate deficit for the year. Chinese authorities halted 2 million tonnes of planned new capacity for 2025 through 2027. The Nonferrous Metals Industry Association proposed strict controls modeled on what worked in aluminum. CSPT said it would set up oversight for member procurement, a supplier blacklist, and collective resistance against parties "maliciously disrupting" the market. MINING.COM covered the announcement in late November 2025.

The catch is execution. CRU is explicit about this. CSPT proposed a 5-10% joint cut in early 2024 and it barely registered in output figures for the year. This time some smelters have signaled real cutbacks but others may switch to scrap copper feed and keep refined output steady while technically reducing concentrate intake. Primary smelting goes down on paper, refined metal keeps flowing.

Mercuria's Daniel Snowden made an interesting point at the FT conference, reported by Fastmarkets. Despite everything, smelters got through 2025 reasonably well because sulfuric acid, gold, and silver by-products covered some of the TC/RC losses. Refined production was still growing, meaning the margin squeeze had not yet reached the point of demand destruction. And China has its own strategic logic: with the US pulling in large copper volumes under tariff fears, less metal is available for Chinese import, increasing pressure on domestic smelters to keep refining regardless of profitability.

The IEA raised a strategic flag. If copper smelting concentrates heavily in one country, the vulnerabilities become a national security and economic security issue for everyone else. China's 2025 rare earth export controls caused temporary shutdowns in global auto manufacturing. Copper is a bigger market and touches every electrical technology. The traditional TC/RC benchmark was built for a diverse market. The IEA's analysis questions whether it still functions when one player dominates the midstream. Traders have already started moving away from it, doing customized prepayment deals to lock in concentrate or anode supply for years at a time.

Glencore did about 951,600 tonnes of copper in 2024, down 6%. But Glencore is also the world's biggest commodity trader. Mining, smelting, and trading all under one roof. The trading arm deals with dozens of mines and smelters globally and the information flow that creates is an advantage no production table measures. Two large copper-cobalt mines in the DRC, plus West Wall, El Pachón, and MARA as greenfield pipeline in Latin America. Benchmark Mineral Intelligence noted in analysis covered by MINING.COM in January 2025 that if Glencore pushes all of these forward alongside African expansions, its growth potential is among the highest in the top ten. Rio Tinto was looking at acquiring Glencore in early 2026. A deal would combine to about 1.6 million tonnes.

Zijin Mining reported 1.07 million tonnes for 2024, 6% growth, fourth place globally. Profit of 32.1 billion RMB, 52% increase. Carbon emissions down nearly 18%. These numbers, from Zijin's own results release, would generate extensive analyst commentary if they came from a Western miner. They receive noticeably less coverage in English-language mining media. Zijin operates across Serbia, the DRC, Tibet, Ecuador. Beyond Zijin, there is MMG under China Minmetals (399,000 tonnes of mined copper in 2024 from the Wikipedia compilation of company data), China Molybdenum, China Railway Resources, and others. The DRC produced approximately 3.3 million tonnes of copper in 2024, up from near zero in 2000, with Chinese companies as the primary drivers through ownership and infrastructure-for-resources deals, according to Visual Capitalist's February 2026 analysis. Company-level rankings scatter this total across multiple entries and make the aggregate less visible.

Southern Copper's Buenavista mine has been in continuous production since 1899. First-half 2025 output was about 207,000 tonnes. A hundred and twenty-five years of continuous operation at a globally significant scale. Southern Copper also controls one of the biggest reserve bases in the copper industry. Where it ranks on production and where it ranks on reserves are two different stories.

Teck and Anglo American merged in late 2025 as Anglo Teck, with copper over 70% of output. Teck's 2024 copper production jumped 50% to 446,000 tonnes, driven by Quebrada Blanca's ramp. Anglo Teck holds five copper mine interests in Canada, Chile, Peru. 10% production growth projected by 2027.

Kamoa-Kakula hit 437,000 tonnes in 2024, 11% growth, still ramping up. Ore grades at the high end for any large operating copper mine. Named the world's lowest carbon-emitting major copper mine in 2023. European buyers are factoring carbon footprint into concentrate pricing and low-carbon copper is starting to carry a structural premium as the EU's CBAM takes effect.

BHP-Anglo in some configuration would mean roughly 1.9 million tonnes combined attributable copper. Glencore-Rio Tinto about 1.6 million. Both deals closing puts 16% of global copper under two companies. The January 2025 MINING.COM analysis on potential combinations laid these numbers out. Iron ore already looks like this. Copper has not gotten there yet.

Resolution Copper in Arizona, 45% BHP and 55% Rio Tinto, has a construction cost estimate around 64 billion dollars. Forty billion pounds of copper over forty years, roughly a quarter of projected US demand. Discovery to production averages 17 years in copper. The capital required to build new mines at this scale keeps rising and the number of companies that can write those checks keeps shrinking.

Average grades continue to decline globally. Chuquicamata went underground in 2019 and output fell from peak to below 300,000 tonnes. Kamoa-Kakula has high grades, low carbon, and room to grow. A mine sitting at fifteenth today with a better grade trajectory than aging top-five mines could swap places within five years. Static rankings do not capture that.

Freeport's leaching work could mean 800 million extra pounds per year by 2030 from existing operations. BHP's Escondida northern pit switched to fully autonomous trucks in late July 2025. Spence became BHP's first completely autonomous mine in 2024 after a two-year conversion. These changes barely move production numbers in the short run but they compound on the cost side.

COMEX copper hit 6.61 dollars per pound on January 29, 2026. LME reached 14,527.50 dollars per tonne the same day. Both records. In Q3 2025 the COMEX price ran up to 5.94 dollars a pound after White House tariff announcements on copper, moderated when refined products were excluded, then pushed back up on fundamentals to 11,067.50 per tonne on the LME by October 29.

BHP projects demand going from around 33 million tonnes per year to 50 million by 2050. BloombergNEF's estimate for investment needed in raw materials under a net-zero scenario runs to 2.1 trillion dollars by 2050. Skarn Associates puts the share of global copper supply exposed to flood or drought disruption at 7% in 2024, rising by 30% by the end of the decade.
