Due to the challenges associated with finding, developing, permitting and mining copper deposits, the higher demand is being met by slow growth of new supply. Mines that are in operation tend to be quite large and operate for decades as copper producers concentrate on mine expansions and brownfield projects aimed at extending mine lifetimes.
Given those factors, investors should keep an eye on the world’s top copper miners and their operations.
This list of the 10 largest copper-mining companies in the world is ranked by attributable copper production for 2024.
As companies' reporting methods for copper production differ, the Investing News Network has calculated attributable copper production for the companies below using figures from company reports and data from Mining Data Online in order to provide investors with the most accurate ranking of global copper production by company.
Copper production: 1.46 million metric tons
BHP is one of the world’s largest mining companies, and its global portfolio of assets includes significant copper mining operations in Chile, Australia and Peru.
According to the company’s quarterly operational review data, the mining giant reported consolidated copper production of 1.46 million metric tons across the calendar year 2024.
Its most significant copper asset is the Escondida mine, the world’s largest copper mine. BHP holds a 58 percent stake in the Chilean operation, which, according to MDO data, produced 2.04 billion pounds of copper in 2024. The company wholly owns the Pampa Norte operations in Chile, which produced 586 million pounds of copper in 2024.
BHP also owns the Olympic Dam polymetallic mine, the largest mine in Australia. The South Australian mine hosts one of the world’s largest copper deposits as well as the largest uranium deposit. In 2023, BHP expanded its portfolio in the state with its acquisition of OZ Minerals and its Prominent Hill and Carrapateena copper operations.
2. Codelco
Copper production: 1.44 million metric tons
The Chilean state-owned Codelco is the world’s third-largest producer with copper production of 1.44 million metric tons in 2024. According to its 2024 annual report, its copper output increased 1.2 percent from 1.42 million metric tons in 2023.
Its largest asset is the Chuquicamata mine located in Northern Chile, between 2017 and 2021 annual production was in the 700 million to 850 million pound range. However, lower grades in recent years have led to production falling below 600 million pounds. In 2024, Chuquicamata increased slightly to 637 million pounds.
The mine transitioned from an open pit to an underground mine beginning in 2019. In its report, the company stated that phase one of its continuity infrastructure project had reached 73 percent completion and that plans for the second phase were undergoing feasibility studies.
The company’s other significant Chilean mines include El Teniente, Quebrada Blanca and Andina.
Copper production: 1.26 million metric tons
Freeport-McMoRan is consistently ranked among the world’s top copper producers, and its share of copper production from its mines totaled 1.26 million metric tons of copper in 2024. The company reported producing 4.21 billion pounds, or 1.9 million metric tons, of the red metal, calculated on a 100 percent basis for all operations except its Morenci joint venture.
The largest contributor to its output is the Grasberg copper-gold mine in Indonesia. The mine itself is a joint venture between Freeport and state-owned Indonesia Asahan Aluminum, with the entities holding interests of 48.76 percent and 51.24 percent respectively. According to MDO, copper output for the mine in 2024 totaled 1.8 billion pounds.
Grasberg has undergone a transition from an open pit to an underground block cave, and expansion work continues at the site. As of the close of 2024, the mine had 469 open drawbells.
Additionally, Freeport holds a 55 percent stake in the Cerro Verde copper-molybdenum complex in Peru. The mine routinely produces between 800 million and 1 billion pounds of copper and is expected to be in operation until 2052.
Its largest US based operation is its 72 percent owned Morenci mine in Arizona, which produced 700 million pounds in 2024. It also owns the Safford and Sierrita mines in the same state.
Copper production: 951,600 metric tons
Mining major Glencore's copper production dipped by 6 percent in 2024 to 951,600 metric tons from the 1.01 million metric tons produced in 2023. The company’s 2024 annual report attributed the decline to lower planned production at its Antapaccay and Collahuasi mines due to factors including lower grades, water constraints and geotechnical challenges.
Located along Chile’s coast, Collahuasi is the company's largest operation, a 44/44/12 joint operation between Glencore, Anglo American (LSE:AAL,OTCQX:NGLOD) and Japan’s Mitsui & Co. (OTC Pink:MITSF,TSE:8031). The mine produced 558,600 metric tons of copper in 2024.
The partners are working to build a large-scale desalination plant designed to help overcome water shortage issues. The plant reached 86 percent completion in 2024 and is expected to begin operating in 2026. Once open, it will provide 1,050 litres of desalinated water per second to the mine via a 194 kilometer pipeline.
Other significant copper-producing assets in the company’s portfolio include Antamina in Peru, Mount Isa in Australia and the Katanga Complex in the Democratic Republic of the Congo.
Copper production: 883,462 metric tons
A majority-owned, indirect subsidiary of Grupo Mexico (OTC Pink:GMBXF), Southern Copper recorded 883,462 metric tons of total copper production for 2024, a 6.9 percent increase over 2023. In the company’s 2024 results, the company attributed the increase to higher production across all operations, with a 10.7 percent increase from its Peruvian assets and a 4.3 percent increase from Mexican production.
The company operates major copper mines in Peru and Mexico and has exploration projects in Argentina, Chile, Ecuador, Mexico and Peru.
Its largest copper-producing asset is the Buenavista mine in Northern Mexico, which sits atop one of the world’s largest porphyry copper deposits. According to MDO, the site produces approximately 700 billion to 750 billion pounds of copper per year.

Copper production: 772,700 metric tons
British miner Anglo American reported a 6.5 percent decrease in copper production to 772,700 metric tons from 826,200 metric tons in 2023.
The company attributed the decline to lower recovery and grades at the Collahuasi and Los Bronces operations in Chile, noting that the planned closure of the Los Bronces processing plant also impacted production. The company holds a 44 percent stake in Collahuasi and 50 percent in Los Bronces.
In addition to Collahuasi, the company also owns a 60 percent stake in the Quellaveco mine in Peru, with Mitsubishi owning the remaining 40 percent. The open pit mine started operating in 2022 and, according to MDO, produced 675 million pounds of copper in 2024.

Copper production: ~502,600 metric tons
CMOC Group is a new addition to the top 10 after its copper production jumped significantly in 2024, with its share of production from its joint venture copper-cobalt mines in the Democratic Republic of the Congo totaling approximately 502,600 metric tons. On a 100 percent basis, the company reported annual copper production of 650,161 metric tons.
The majority of CMOC's copper production came from its Tenke Fungurume copper-cobalt mine, an 80/20 joint venture with the state-owned mining firm Gecamines. According to MDO data, the mine has experienced significant growth over the past few years, ramping up from 400 million pounds of copper in 2020 to 618 million pounds in 2023.

Its Centinela mine is another significant producer, with 224,000 metric tons of copper mined in 2024. The company is constructing a second concentrator at Centinela that, once it comes online in 2027, should add 144,000 metric tons of copper production annually and extend Centinela’s mine life by 15 years to 2051.
The company's other Chilean joint ventures are the Antucoya and Zaldivar mines.
Copper production: 358,910 metric tons
