However amid the push to dig extra, one query will get far too little consideration: Who will truly course of what comes out of the bottom?
Between mining and the completed product lies a fancy chain of separation, refining and superior manufacturing. For the reason that Nineteen Nineties, nonetheless, the US has misplaced a lot of its important mineral processing capability.
Rebuilding home mineral provide chains will rely not solely on useful resource availability and funding, but additionally on whether or not the U.S. can rebuild the technical experience and industrial programs required to course of these supplies on a big scale.

How America misplaced its lead
The USA was a world chief in uncommon earth minerals from 1965 by way of the mid-Nineteen Eighties. It produced about 15,000 metric tons a 12 months, about 3 times the quantity produced by the remainder of the world.
The Mountain Cross mine in California equipped nearly all of the world’s uncommon earth parts utilized in electronics and the protection {industry}. American metallurgists, chemical engineers and processing amenities had important experience in its manufacturing and processing.
Nevertheless, environmental harm, together with wastewater pipeline leaks that launched radioactive wastewater into the Mojave Desert in the course of the Nineteen Eighties and Nineteen Nineties, and tightening rules elevated working prices in the US. Throughout that interval, a lot of the world’s manufacturing base for uncommon earth parts shifted to China, the place labor prices had been decrease and environmental rules had been much less stringent.
As manufacturing grew overseas, U.S. manufacturing of uncommon earth parts fell sharply – to close zero by the early 2000s, in keeping with the U.S. Geological Survey.
Lately, as a lot as 90% of the uncommon earth minerals extracted in the US and allied nations have been shipped to China for processing. In 2024, the U.S. relied on imports for about 80% of its uncommon earth compounds and metals.
Why bringing processing again just isn’t easy
The U.S. authorities is now pushing to extend home important minerals manufacturing, citing nationwide safety. However constructing a processing facility just isn’t like opening a warehouse.
These amenities require years of allowing, extremely specialised gear and a workforce educated in metallurgy, chemical engineering and industrial programs operation. The time from funding choice to manufacturing can stretch throughout a decade.
The U.S. at present has two home uncommon earth mining places. One is in southeast Georgia, which extracts uncommon earth parts as a byproduct of heavy mineral sand mining. The opposite is Mountain Cross, which produces bastnaesite, a uncommon earth carbonate mineral. The mines produced about 51,000 metric tons of uncommon earth mineral concentrates in 2025, whereas the U.S. imported about 21,000 metric tons of uncommon earth compounds, most of them from China, in keeping with 2025 U.S. Geological Survey information.
The U.S. has additionally misplaced experience. Mining and mineral engineering teaching programs now produce just a few hundred graduates per 12 months, nicely under the degrees of previous a long time. The variety of accredited applications has declined because the Nineteen Eighties. Many school members are nearing retirement.
Trade projections estimate that the mining workforce might want to develop considerably within the coming years to satisfy rising demand. Specialised expertise in areas corresponding to uncommon earth separation, metallurgical testing and environmental programs design require years of coaching and sensible expertise. And whereas mining can produce high-paying jobs, the {industry} additionally has a status for environmental harm and dangerous circumstances.
Environmental compliance is a part of the talent set
Processing important minerals is a soiled {industry}. That reality has made it harder for processing and refining corporations to function within the U.S.
For instance, separating uncommon earth parts usually includes chemical processing with acids and solvents. When waste streams are poorly managed, these processes can produce poisonous wastewater and air air pollution and contribute to soil erosion. In components of China the place uncommon earth manufacturing expanded quickly within the Nineteen Nineties and 2000s, contamination from mining and processing has polluted rivers and broken close by farmland, and the wastewater can seep into soil and groundwater.
Within the U.S., trendy amenities should meet strict federal and state requirements for air high quality, water discharge and waste administration that elevate the price of processing. These rules had been developed in response to environmental disasters, just like the Cuyahoga River fireplace of 1969, when industrial oil and waste on the river burned, and dangerous waste crises just like the Love Canal catastrophe that led to landmark environmental legal guidelines.
Working a refinery or separation facility in compliance with regulatory requirements as we speak requires experience in air pollution management, waste therapy and sustainable course of design. That requires a workforce expert in supplies science and engineering and with data of environmental programs. With out environmental experience, operational dangers, regulatory challenges and undertaking delays can enhance, affecting long-term viability.
Easy methods to construct a US provide chain
Rebuilding U.S. provide chains would require greater than increasing extraction.
Canada’s important minerals technique provides an instance. It connects mining tasks to battery and electrical automobile manufacturing by funding processing amenities, growing regional provide chain hubs and investing in workforce coaching applications tied to these industries.
Australia has mixed important minerals insurance policies with incentives and public financing to encourage home mineral processing, whereas additionally increasing college and vocational coaching in mining, metallurgy and mineral processing.
The USA has most of the key substances wanted to rebuild its processing capability, together with analysis universities and employees with transferable industrial expertise. Land-grant and technical universities may develop applications that combine mining, supplies science, environmental restoration and recycling. In areas corresponding to Appalachia, the place coal’s decline has left employees with expertise however few job alternatives, retraining applications for brand spanking new mineral restoration jobs may assist individuals transition to a brand new {industry}.
A number of federal applications help components of this transition, together with analysis hubs that develop new extraction and processing applied sciences, apprenticeship initiatives and university-industry partnerships. Nevertheless, these efforts are unfold throughout a number of businesses, with restricted coordination to align priorities and funding.
The actual bottleneck
America’s important minerals technique is usually mentioned by way of geology and geopolitics – the place assets are situated and who has entry to them.
However provide chains rely upon individuals and programs. That’s America’s actual bottleneck in making a home provide chain.
A profitable home provide chain would require employees who know the way to separate neodymium from praseodymium, function solvent extraction circuits and keep hydrometallurgical crops inside regulatory requirements. These are extremely specialised expertise that take years to develop.
The USA has important mineral assets and rising coverage help. Now, it wants to concentrate to the workforce and industrial capability wanted to remodel these assets into usable supplies.
This hole developed over a long time. Addressing it can possible require sustained funding alongside broader mineral coverage modifications corresponding to allowing reforms and funding in home processing amenities.
