Steel and iron products

World's largest refractory materials producer, supplying ~35% of global steel industry refractory needs; controls key magnesite mines in Austria and Brazil; steel accounts for ~70% of global refractory consumption.

Vale S.A. (B3: VALE3; NYSE: VALE; HQ Rio de Janeiro; ~$42B revenue 2023) is Brazil's largest mining company and a major global nickel producer (~7% global nickel supply). Vale operates the Clydach Nickel Refinery in Wales, UK — one of the few Western Class 1 nickel refineries capable of producing battery-grade nickel sulfate — and holds a majority stake in Vale Base Metals Ltd (formerly PT Vale Indonesia / PTVI), which operates nickel operations in Sorowako, South Sulawesi, Indonesia, including a growing HPAL project (Pomalaa, Southeast Sulawesi, with Huayou and Ford Motor as JV partners). Vale's nickel business spans Canadian sulfide mining (Sudbury, Ontario; Thompson, Manitoba; Voisey's Bay, Labrador) and Indonesian laterite operations. Vale's Clydach refinery is one of the last large-scale European Class 1 nickel refining assets; its continued operation is strategically important for Western EV battery supply chain ambitions.

Holds 30% of Escondida (world's largest copper mine) and operates Kennecott (Utah) and Oyu Tolgoi (Mongolia, expected ~500kt/yr 2028-2036). Major global copper miner.

BHP Group (ASX/LSE/NYSE: BHP; HQ Melbourne; ~$55B revenue) is the world's largest mining company by market capitalization and a critical node in global process water infrastructure. BHP's Escondida copper mine (Atacama Desert, Chile) — the world's single largest copper mine, producing ~5% of global copper supply — required a $3.4 billion seawater desalination plant (Escondida Water Supply desalination facility, Punta Patache, Antofagasta coast) to pump desalinated seawater ~170 km and 3,500 meters in elevation to the mine. Escondida now recycles ~75% of process water and is transitioning to seawater-only operations. BHP's Olympic Dam mine (South Australia) is the world's largest known uranium deposit and requires water from the Great Artesian Basin (world's largest confined groundwater aquifer) — a different but equally critical water dependency. BHP operates across two of the world's most consequential water-constrained mining regions.

Swiss-British commodity giant, second-largest cobalt miner globally. Operates Mutanda and Kamoto Copper Company mines in DRC, plus Murrin Murrin (Australia). Produced 38,200 tonnes cobalt in 2024.

Australia's third-largest iron ore miner; ~14% of global seaborne iron ore; all production from Pilbara, WA (Solomon, Chichester, Iron Bridge hubs); founded 2003 by Andrew Forrest who broke the BHP/Rio Tinto duopoly on Pilbara infrastructure. Annual export ~190 million tonnes. Lower-grade ore (57-60% Fe) than Rio Tinto/BHP benchmark, priced at discount.

Anglo American plc (London; JSE/LSE: AAL; ~$32B revenue; ~$35B market cap) is a major diversified miner with significant copper exposure through Chilean and Peruvian operations. Anglo American co-owns Collahuasi (44%; one of Chile's largest copper mines, ~600,000 tonnes/year Cu production capacity, Tarapacá Region) and Los Bronces (open-pit porphyry copper mine near Santiago; ~200,000 tonnes/year Cu). Anglo American's 2024 restructuring — driven by a rejected BHP takeover bid at ~$39B — included a plan to spin off or sell its platinum, coal, and nickel businesses to focus on copper, iron ore, and crop nutrients. This restructuring signals Anglo American's strategic view that copper is the defining metal of the energy transition. Anglo American's copper production is approximately 660,000-750,000 tonnes/year (combined mines), representing ~4% of global copper mine supply.

Teck Resources Limited (Vancouver; NYSE: TECK; ~$9B revenue) is one of the world's largest integrated zinc producers and a major Western indium producer. Indium is recovered as a byproduct at Teck's Trail Operations in Trail, British Columbia — one of the largest integrated zinc and lead smelting complexes in the world. Teck produces 99.995%-minimum-purity indium at Trail with an annual capacity of approximately 75 tonnes, representing ~22% of US import supply. Teck has expanded its indium processing capability to meet ITO manufacturer demand. Trail Operations processes zinc concentrates from Teck's Red Dog mine (Alaska) and third-party sources. Teck sold its steelmaking coal business to Glencore in 2024, sharpening its focus on copper and zinc — both critical mineral supply chains.

UK-listed global refractory and molten metal flow control company; ~£1.8B revenue; produces continuous casting refractories (slide gates, nozzles, stopper rods) and steel plant ceramics. Flow control is Vesuvius's specialty — the nozzles that control molten steel flow from ladle to tundish to mold in continuous casting.

Japan's largest refractory company; Nippon Steel subsidiary; produces magnesia-carbon bricks, high-alumina refractories, and monolithics for steel, glass, and cement industries. Kita-Kyushu Japan is primary production site; strong position in Japanese domestic market and export to Asian steel mills.

World's largest publicly traded metal and electronics recycler; ~75% of earnings from North America; processes and exports ferrous and non-ferrous scrap from 250+ facilities across US, Australia, New Zealand, UK. Major supplier of shredded scrap to EAF steelmakers in Turkey, South Asia, and East Asia.

Third-largest US steel producer; second-largest domestic heavy rail producer via Columbia City, Indiana Structural and Rail Division. Rail capacity: ~300,000 tons/year; heat-treating capacity for 350,000 tons of head-hardened premium rail. Produces 320-foot long rails (same as Pueblo). All major US Class I railroad approvals. SDI's Columbia City facility also produces structural steel (wide-flange beams). SDI expanded Columbia City from 1 million to 1.6 million tons/year total capacity. First domestic US rail producer to receive simultaneous approval from all Class I railroads.

Largest private ferrous and non-ferrous scrap processor in Europe; operates 150+ sites across UK, Germany, Netherlands, Poland; processes ~8 MT of scrap annually; major exporter to Turkish EAF mills via Rotterdam. Private company (Philip Sheppard family).

Major US ferrous scrap processor; Nucor Corporation subsidiary (Nucor acquired DJJ in 2008 for $1.44B to vertically integrate scrap supply for its EAF mills); operates 50+ scrap yards across the US Midwest and Southeast; Nucor's internal scrap supply secures ~30% of its raw material needs.

One of the few remaining large-scale US producers and exporters of metallurgical coal; operates two underground mines in the Warrior coalfield of Alabama, exporting primarily to European and Asian steelmakers.
