Producers and processors: the fifteen miners and refiners who set the critical minerals supply floor

What it is

The producers-and-processors beat covers fifteen companies whose mines, smelters and refineries set global critical-minerals supply. The roster spans three tiers: diversified miners for whom critical minerals are one segment among several (BHP, Rio Tinto, Vale, Glencore); state-owned or state-linked champions whose output decisions carry explicit policy weight (Codelco in Chile; CMOC, Zijin Mining, Ganfeng, Tianqi and Huayou Cobalt in China; Nornickel and Rusal in Russia); and commodity specialists whose balance sheets move almost entirely with one material (Albemarle and SQM on lithium, Freeport-McMoRan on copper). The output of these fifteen firms touches every EV factory floor, every grid-storage project and every defence supply chain that depends on processed metal, which is why pricing decisions made in Santiago, Guangzhou or Norilsk surface in policy debates in Washington, Brussels and Canberra.

History

The sector's current shape formed between 2010 and 2022. China directed state capital into lithium and cobalt refining, vaulting Ganfeng, Tianqi, CMOC, Zijin and Huayou Cobalt from regional operators to global suppliers. By 2024, China processed roughly 70% of world lithium and cobalt. The IEA's 2025 Global Critical Minerals Outlook put the top three refining nations at an 86% average market share across key minerals, up from 82% in 2020, heavily concentrated in China. The 2016-2022 lithium boom enlarged Albemarle and SQM; Chile's 2023 National Lithium Policy made Codelco the state instrument for asserting Chilean control over both copper and lithium. The 2023 lithium price collapse forced restructuring across Albemarle (US$1.2 billion net loss in 2024), SQM, Ganfeng and Tianqi, while CMOC and Zijin, cushioned by state balance sheets, used the downturn to expand in the Democratic Republic of the Congo (DRC) and Serbia.

Current state

Three live tensions define the beat as of mid-2026. First, the US Section 232 refined-copper review, proposing duties of 15% in 2027 rising to 30% in 2028, would hand pricing power to Codelco and Freeport-McMoRan as the largest US-market copper suppliers, tracked in the COMEX inventory squeeze and the Section 232 deadline. Second, CMOC's TFM copper-cobalt mine in the DRC faces government quota disputes in the TFM standoff, periodically throttling cobalt output and tightening the global cobalt market alongside Glencore's Katanga assets. Third, Western sanctions have reoriented Nornickel's and Rusal's export flows toward China: the Aughinish alumina dispute is testing whether the EU can hold sanctions pressure on Russian-owned refining capacity located inside Ireland.

Relationships

Albemarle and Tianqi share control of Australia's Greenbushes mine, the world's largest hard-rock lithium deposit, jointly setting spodumene supply even as they compete downstream in processed lithium. SQM's Q1 2026 results reflect the first full quarter under the restructured SQM-Codelco joint venture in Chile's Salar de Atacama, reshaping how the world's largest lithium brine reserve is priced and allocated. In the DRC, CMOC and Glencore are the two dominant copper-cobalt operators, competing for logistical corridors and government quota allocations on overlapping ground. Zijin Mining has acquired copper and gold assets in Serbia, the DRC and Papua New Guinea, overlapping Freeport-McMoRan's copper footprint at several projects. Ganfeng's solid-state battery and Argentine lithium work shows how Chinese producers are integrating downstream toward cell chemistry, not stopping at refined salt. Huayou Cobalt sits at the midstream junction, converting DRC cobalt ore into precursor cathode material sold both to Chinese manufacturers and Western automakers building non-China supply chains.

What to watch

The key signals: whether the US Section 232 copper duty arrives in mid-2026 and at what rate; whether DRC's quota disputes with CMOC and Glencore escalate toward forced contract renegotiation; whether Nornickel's pivot to Chinese buyers becomes permanent, bifurcating the palladium-nickel market; and whether Australian political pressure forces a domestic smelting stage on the Albemarle-Tianqi Greenbushes joint venture before export. The World Bank projects production of graphite, lithium and cobalt could rise nearly 500% by 2050, a scale that makes the capital-allocation decisions of these fifteen companies among the most consequential in the global economy.
