How it's made

The process

  1. 01

    Copper ore mining

    Open-pit or underground extraction of copper ore, typically containing 0.5–2% copper grade. Ore is blasted, loaded, and trucked to primary crushers. Largest operations (Escondida, Grasberg, Collahuasi) each process 100,000+ tonnes of ore per day.

  2. 02

    Concentration (froth flotation)

    Crushed ore is ground to fine particles and mixed with water and chemical reagents in flotation cells. Air bubbles selectively attach to copper sulfide minerals and float to the surface, producing copper concentrate (25–35% Cu) and discarding waste tailings. Requires large volumes of water — roughly 90 m³ per tonne of copper produced.

  3. 03

    Smelting

    Copper concentrate is fed into high-temperature furnaces (1,200°C+) where sulfur burns off as SO₂ gas, which is captured and converted to sulfuric acid as a byproduct. The output is blister copper at ~98–99% purity. China now accounts for over 50% of global copper smelting capacity.

  4. 04

    Electrolytic refining

    Blister copper anodes are dissolved electrolytically into a copper sulfate solution, and 99.99% pure copper cathodes are deposited on steel blanks. The process consumes ~250–300 kWh per tonne of cathode copper — electricity is the dominant operating cost. Precious metal slimes (gold, silver, platinum) collect at the bottom and are recovered separately.

  5. 05

    Copper rod production (continuous casting)

    Copper cathodes are melted and continuously cast into copper rod (typically 8mm diameter) using the Southwire or Contirod process. Rod is the primary feedstock for wire drawing. Global rod production capacity is approximately 20 million tonnes per year.

  6. 06

    Wire drawing

    Copper rod is pulled through progressively smaller tungsten carbide or polycrystalline diamond dies — often 14 or more passes — to reduce diameter to final gauge (ranging from 0.05mm magnet wire to 25mm building wire). Intermediate annealing restores ductility lost during cold working.

  7. 07

    Insulation and jacketing

    Drawn copper wire is coated with PVC, XLPE, PTFE, or other polymer insulators via continuous extrusion. Finished wire is tested for conductivity, insulation resistance, and tensile strength before spooling. High-performance cables (aerospace, submarine) receive additional shielding and armoring.

State Grid Corporation of China (Beijing; 100% state-owned; ~USD 500B revenue — world's largest utility by revenue) operates the power grid for 26 of China's 34 provinces/regions, transmitting electricity from coal-fired power plants and the Yangtze/Yellow River hydropower systems to industrial consumers. State Grid delivers electricity to China's aluminum smelters — which consume ~60% of global aluminum's total electricity demand (~700 TWh/year). The massive ultra-high-voltage (UHV) transmission lines built by State Grid carry hydropower from Sichuan and Yunnan provinces (Yangtze River tributaries, including Three Gorges Dam) to eastern aluminum smelting clusters. State Grid also manages electricity to China's chlor-alkali industry (world's largest, ~30% global capacity) and lithium processing operations in Sichuan, Qinghai, and Jiangxi. China's aluminum smelter electricity is predominantly coal-fired (~60-70% of Chinese aluminum electricity), making Chinese aluminum the most carbon-intensive in the world.

Codelco (100% Chilean state-owned; HQ Santiago; ~$15B revenue) is the world's largest copper producer and the operator of Chile's most iconic copper mines — Chuquicamata, El Teniente, and Andina — all in high-altitude Atacama Desert regions facing severe water stress. Codelco's mines collectively consume billions of liters of water per year from the Atacama's scarce freshwater resources (rivers, aquifers) that are simultaneously needed by indigenous communities (Atacameño people) and the Atacama's extreme-endemic ecosystem. Codelco is investing in seawater desalination and water recycling to reduce freshwater dependency under pressure from Chile's 2022 National Water Strategy and reformed Water Code, which tightened water rights allocation. Codelco's water sourcing decisions are intertwined with Chilean government policy — as a state-owned enterprise, Codelco's water use is both a commercial question and a public sovereignty question.

In 2022, corrosion inspection shutdowns at French reactors including units at Cattenom reduced French nuclear output by ~80 TWh — contributing to the European energy price spike that curtailed European aluminum and chlor-alkali production.

ERCOT — Texas Interconnection Grid (Houston Hub) →

US

Electric Reliability Council of Texas (ERCOT) · Texas

The ERCOT grid (Houston pricing hub) is the primary electricity market for Texas Gulf Coast industrial consumers — including Olin Corporation chlor-alkali plants (Freeport TX; ~900,000 t/yr chlorine capacity), Occidental Chemical (OxyChem) plants, and chemical complexes on the Houston Ship Channel. ERCOT's physical isolation from Eastern/Western Interconnections means Texas industrial consumers have no import alternative during grid emergencies. During Winter Storm Uri (February 2021), ERCOT prices reached the $9,000/MWh market cap for ~90 hours; many industrial consumers (including chemical plants) had to shut down completely. Chlor-alkali electrolysis cannot be ramped quickly — unplanned shutdowns damage electrolyzer cells and can take weeks to restart.

BHP Group · Antofagasta Region, Atacama Desert · mine

Escondida (Atacama Desert, Antofagasta Region, Chile; altitude ~3,050m; BHP 57.5%, Rio Tinto 30%, JECO 12.5%) is the world's single largest copper mine, producing approximately 1.1-1.2 million tonnes of copper per year — approximately 5% of global copper supply from a single mine. Discovered 1981 by Utah International/Getty Oil geologists following geologic interpretations of satellite imagery. Opened 1990. Two open-pit mines (Escondida Norte and Escondida pit), plus sulfide heap leach and oxide operations. Escondida processes ore through two concentrators (Los Colorados and Laguna Seca) producing copper ore concentrate (25-30% Cu). The mine employs approximately 13,000 workers and contractors. Escondida's water supply system — converting seawater from the Pacific (Pacific coast ~170km away) via a desalination plant and pumping 3,050m uphill — is one of the world's largest industrial water systems.

Freeport-McMoRan · 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.

Hydro-Québec · James Bay, Quebec

The La Grande Complex (James Bay project; 8 generating stations; ~16,000 MW installed capacity) is North America's largest hydroelectric development — built 1971-1996 and expanded through LG-1 through LG-4 and associated projects. It generates the bulk of Hydro-Québec's electricity used to power Quebec's aluminum smelters. The James Bay territory is Cree First Nation land — the original 1975 James Bay and Northern Quebec Agreement (JBNQA) was landmark indigenous land rights settlement. Disruption of James Bay complex (extreme low water years, ice dam events) would directly curtail Quebec aluminum production.

690 MW hydropower station in East Iceland; built 2007-2009 specifically to power the Alcoa/ÍSAL Fjarðaál aluminum smelter (346,000 t/yr) near Reyðarfjörður; Iceland's largest power plant. The dam's construction required damming the Jökulsá á Dal and Jökulsá í Fljótsdal glacial rivers — a highly controversial project (Kárahnjúkar dam protests). The Fjarðaál smelter contract was the primary justification for the entire USD 1B+ hydropower investment. Demonstrates how stranded Icelandic hydro resources specifically attract energy-intensive aluminum smelting industry.

Newmont Corporation · Apurímac · mine

Las Bambas copper mine (Apurímac region, Peru; operated by MMG Limited, Chinese state-owned; formerly Glencore before 2014 sale) is Peru's second-largest copper mine and has experienced more community road blockades than any other mine in South America — over 200 days blocked in 2022 alone — primarily over water rights, land use, and environmental impacts on local communities' water sources. The Chalhuahuacho and Fuerabamba communities depend on surface water sources that share the watershed with mine operations. Las Bambas produces ~450,000 tonnes/year of copper (2% of global supply) and can be shut down by community road blockades with no practical legal remedy — illustrating that process water access in Peru is inseparable from social license. Peru's mining sector contributes 60% of export revenues yet faces systemic water conflicts. Note: listed under newmont-corporation as Newmont is used as the canonical 'Peru mining' company node here; actual Las Bambas operator is MMG.
