Andalusia · smelter

Largest copper smelter in Europe by concentrate throughput; fully owned by Freeport-McMoRan via its Atlantic Copper subsidiary. Located in Huelva, on the Rio Tinto estuary in Andalusia — the same region where the ancient Phoenicians and Romans mined copper from Rio Tinto (literally 'Red River') deposits 2,500 years ago. Processes ~1.2 million tonnes of copper concentrate per year, producing ~315,000 tonnes of cathode annually. Primarily processes Freeport's own North American and Indonesian concentrate, with some third-party concentrate. Produces sulfuric acid (sold to Spanish fertilizer manufacturers and Moroccan phosphate processors) and precious metal byproducts. Source: https://www.atlanticcopper.com/en/smelter-and-refinery

Papua · mining

Grasberg mine complex in the Sudirman Mountains of Papua Province, Indonesia. One of the world's largest copper and gold mines. Operated by PT Freeport Indonesia (majority owned by Freeport-McMoRan). Has transitioned from open-pit (Grasberg Open Pit, now exhausted) to underground block cave mining (Grasberg Block Cave, Deep Mill Level Zone). Production of ~800,000 tonnes/year copper concentrate equivalent. Indonesian government (through Inalum/MIND ID) holds 51% stake. Subject to periodic export bans, smelter conversion requirements under Indonesian mining law, and labor disputes.

Arizona · smelter

Primary copper smelter in the U.S.; one of only two remaining U.S. copper smelters (along with ASARCO Hayden smelter). Located in Miami, Gila County, Arizona. Processes concentrate from Freeport's Morenci mine and purchased third-party concentrate into anode copper; electrolytic refining produces LME-registered cathode. U.S. copper smelting capacity has declined dramatically — from 16 smelters in 1970 to 2 operational today. Source: https://www.fcx.com/operations/north-america

Arizona · mining

Largest copper mine in North America by production; open-pit operation in Greenlee County AZ; produces copper cathode via SX-EW process.

Arizona · processing

SX-EW (solvent extraction / electrowinning) copper cathode operation at Safford, Graham County, Arizona. Produces ~100,000 tonnes of LME-registered copper cathode per year from oxide ore without conventional smelting. Noted as one of the most sustainable copper operations in the Americas — uses minimal water (closed-loop process), produces no SO2 emissions (no smelting furnaces), and operates a low-carbon direct-cathode process. SX-EW cathode meets LME Grade A specification directly without electrolytic refining. Source: https://www.fcx.com/operations/north-america/safford

Papua Province · mine

World's second-largest copper mine and largest gold mine. Underground transition completed ~2019. Freeport (via PT Freeport Indonesia) holds 48.76%; MIND ID (Indonesian state) 51.24%. Produced ~1.0B lbs copper/yr (FCX equity share) in 2024–2025.

Papua Province · mine

Grasberg (Papua Province, Indonesia; altitude ~4,200m; FCX 48.76%, PT Mineral Industri Indonesia/Inalum 51.24%) is one of the world's largest copper and gold deposits by reserves, and historically the world's largest gold mine as a copper byproduct. Discovered by Dutch geologist Jean-Jacques Dozy in 1936; Freeport began developing the Ertsberg ore body in 1967 under a Contract of Work with the Indonesian government; Grasberg pit discovered 1988. The massive open-pit operation (Grasberg Open Pit — now largely mined out) transitioned to underground block cave mining (Grasberg Block Cave, Deep Mill Level Zone/Deep MLZ) in the late 2010s. Annual copper production approximately 370,000-450,000 tonnes (concentrate and cathode combined) and 1.2-1.6 million ounces gold. The 2018 divestiture to PT Mineral Industri Indonesia (Inalum) — required under Indonesia's Mining Law — transferred operating control to a new structure: PT Freeport Indonesia (PTFI) is 51.24% Inalum and 48.76% FCX, with FCX retaining operating management.

Arizona · mine

Morenci (Greenlee County, Arizona; FCX 72%, Sumitomo Metal Mining/Sumitomo Corporation 28%) is the largest copper mine in the United States, producing approximately 430,000-490,000 tonnes/year of copper — primarily as copper cathode via sulfuric acid heap leach/SX-EW (solvent extraction-electrowinning) rather than as copper ore concentrate. Morenci is an open-pit porphyry copper deposit first mined by Phelps Dodge (founded 1834) from 1872; it is one of the oldest continuously operating copper mines in North America. FCX acquired Phelps Dodge (and Morenci) in 2007 for $25.9B. Morenci represents approximately 50% of total US domestic copper mine production — making FCX the dominant US copper miner by a wide margin. The town of Morenci (company town built by Phelps Dodge) was demolished and rebuilt multiple times as the open pit expanded. Source: FCX Annual Report 2024; USGS Mineral Commodity Summaries 2024.
