Reinventing America’s critical minerals supply chain: mid‑stream focus for mine planners

30 Second Briefing
The US “One Big Beautiful Bill” allocates US$7.5 billion to critical minerals and is backed by a further US$1 billion in Department of Energy funding for lithium, nickel, rare earths, gallium and graphite, but the impact will hinge on directing money to mid‑chain extraction, refining and processing rather than simply expanding mining. Arizona holds 71% of US copper reserves, yet in 2024 the country consumed 52,000 tonnes of graphite while importing about 60,000 tonnes, with zero domestic production and 90% of rare earth refining controlled by China. Emerging projects such as Ucore’s rare earth facility in Louisiana, USA Rare Earth’s LCM metallisation and strip‑casting assets, and Idaho plants processing Sheep Creek ore show where funding tied to energy‑efficient refining, digital ore characterisation and circular recovery could materially de‑risk grid and storage supply chains.
Technical Brief
- Scaling mining, processing and refining technologies is flagged as lower capex/complexity than semiconductor fabrication build‑outs.
- Funding is urged towards advanced refining that reduces both energy and water intensity versus legacy hydrometallurgical flowsheets.
- Circular flowsheets recovering critical minerals from tailings, slags and end‑of‑life products are prioritised over new greenfield pits.
- Digital tools are singled out for optimising extraction and processing efficiency, implying heavier use of real‑time ore characterisation and control.
- For other jurisdictions planning critical mineral strategies, the piece implies that mid‑stream processing and recycling hubs may yield higher resilience than pure mine expansion.
Our Take
The DOE’s $1 billion spread across five initiatives sits at the upper end of project-scale public support in our Mining coverage, signalling that Ucore’s Louisiana rare earth facility and Montana’s Sheep Creek deposit are being treated as strategic infrastructure rather than conventional mine developments.
With Arizona already supplying 71% of US copper and China controlling about 90% of rare earth refining capacity, the US focus on domestic refining and processing mirrors Latin America’s recent IDB–EU-backed push to capture more value in copper, lithium and rare earths rather than exporting raw concentrates.
The fact that none of the graphite used in the US in 2024 was domestically produced, while DOE is backing two new battery-grade lithium processing projects, suggests graphite anode material could be the next major bottleneck targeted by federal funding after lithium and rare earth elements.
