Cobalt and Molybdenum Metals (catalyst precursors)

Chinese mining giant that is the world's largest cobalt miner as of 2024. Operates Tenke Fungurume (TFM) and Kisanfu (KFM) mines in DRC. Produced 114,000 tonnes cobalt in 2024, representing ~41% global market share.

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.

U.S. copper mining and smelting company (NYSE: FCX; HQ Phoenix, AZ; ~$23B revenue); largest publicly traded copper company in the world. Freeport operates copper mines in Arizona (Morenci — world's largest copper mine by production; Bagdad, Safford, Sierrita), New Mexico (Chino, Tyrone), Indonesia (Grasberg — world's largest single copper deposit), and Peru (Cerro Verde). Freeport refines copper into cathode via two pathways: (1) conventional smelting at its Miami, Arizona smelter (processes concentrate from Morenci and purchased concentrate), and (2) SX-EW (solvent extraction / electrowinning) cathode production directly from oxide ore at Bagdad AZ, Safford AZ, Chino NM, and Tyrone NM. Freeport also owns Atlantic Copper (Huelva, Spain — largest copper smelter in Europe by concentrate throughput) via its European subsidiary. Grasberg (Indonesia) is operated via PT Freeport Indonesia, a joint venture with the Indonesian government (51% ownership). Freeport is the largest single copper producer in North America.

Major diversified mining and commodities trading company; produces sulfuric acid as byproduct at its copper, zinc, and lead smelters globally (Australia, Canada, Kazakhstan, South Africa, Philippines, Peru, etc.). One of the world's largest merchants of sulfuric acid from smelting operations. Also one of the world's largest sulfur traders — trades recovered sulfur from refineries and intermediates it to fertilizer manufacturers. Glencore's dual position as a smelter byproduct H2SO4 producer AND sulfur trader gives it market intelligence across both supply sources.

Huayou Cobalt Co., Ltd. (Quzhou, Zhejiang Province; SZSE: 603799; ~¥60B+ revenue) is the world's largest producer of battery-grade cobalt sulfate — estimated 25-30% of global CoSO4 supply. Huayou controls the full cobalt value chain: mining and concentrating cobalt ore in the DRC through its Mikas and Huacobalt DRC subsidiaries (Katanga Province, near Kolwezi), shipping cobalt hydroxide intermediates to Quzhou, refining to cobalt sulfate at the Quzhou facility (capacity ~70,000 tonnes cobalt content annually across all cobalt products), and selling to NMC cathode precursor manufacturers in China, Japan, and South Korea. Huayou is CATL's primary cobalt sulfate supplier. In 2021-2023, Huayou aggressively expanded upstream DRC cobalt hydroxide capacity and downstream cathode precursor (PCAM) production, integrating vertically from mine to precursor. Huayou's Quzhou facility is the single largest cobalt chemical refinery in the world. The company is listed on the Shenzhen Stock Exchange and is partially state-aligned via CIC (China Investment Corporation) linkages.
