Oklahoma critical minerals refining push: infrastructure and power notes for engineers

30 Second Briefing
Oklahoma is positioning itself as a critical minerals processing hub rather than a mining state, anchored by Emirates Global Aluminium’s proposed US$4 billion primary aluminium smelter at the Port of Inola on the McClellan–Kerr Arkansas River system and backed by surplus low‑cost power from wind and natural gas. USA Rare Earth is building a vertically integrated rare earth magnet plant in Stillwater with about US$1.6 billion in public and private funding, while Stardust Power (NASDAQ: SDST) is advancing a lithium refinery in Muskogee with Sumitomo offtake and key permits secured. The cluster targets defence and aerospace demand around Tinker Air Force Base and other installations, aiming to plug the “missing middle” between raw mineral supply and finished components.
Technical Brief
- State strategy explicitly prioritises refining, magnet manufacturing, recycling and smelting over primary extraction to capture mid‑stream margins.
- Federal incentives linked to the CHIPS and Science Act and similar programmes are a key part‑funding mechanism for these plants.
- For other US states, Oklahoma’s model illustrates how power‑rich, non‑mining regions can anchor mid‑stream critical‑minerals capacity.
Our Take
Oklahoma’s push into refining for lithium, rare earths and aluminium sits within a cluster of recent ‘critical minerals’ coverage that is otherwise dominated by upstream projects in Latin America and major miners like Rio Tinto and BHP, signalling that midstream US capacity remains relatively sparse in our database.
The state’s roughly 65% energy surplus and natural gas base positions facilities at the Port of Inola and along the McClellan–Kerr Arkansas River Navigation System to compete with Gulf and Mississippi River industrial hubs, especially as power-intensive aluminium and magnet plants seek lower-cost, lower-volatility power in the United States.
With USA Rare Earth and Stardust Power both targeting magnets and batteries, this Oklahoma build-out complements the security-focused critical minerals themes flagged in our January 27, 2026 piece on US-backed supply chains, and likely strengthens the case for offtake-linked support from defence-related users around Tinker Air Force Base and other military installations in the state.
