We’re Mining the Metals We Still Import

If even 1 percent more of these discarded metals were collected, the U.S. could dramatically reduce imports. If recycling and recovery infrastructure grow together, the U.S. could achieve long-term independence.

"Does the Nation’s mine waste contain valuable critical mineral resources? The U.S. Geological Survey says “yes.” Identifying and recovering critical minerals from legacy and modern mine waste may help generate a resilient domestic supply of vital resources while aiding in remediation efforts."

The 1% That Changes Everything

A recent report published in Science highlighted a surprising reality in U.S. mining: valuable metals are being dug up and then thrown away. When mining companies extract primary metals such as gold, copper, and iron, the surrounding rock often contains rare earth elements and other critical minerals. Instead of being captured, these metals are typically discarded in waste piles or tailings facilities.

According to the research, recovering just 1 percent of certain rare earth elements already being unearthed (but not collected) would be enough to replace current U.S. imports. In other words, the United States is already mining a significant portion of the metals we currently buy overseas. We’re just not recovering them.

This finding has major implications for the metal recycling industry, the U.S. supply chain, and the global market for strategic materials.

What This Means for the Metal Recycling Industry

The recycling industry has long played a critical role in reducing dependence on foreign sources of strategic metals. However, rare earth elements (REEs) have always been difficult to recycle because they are used in small quantities across complex products like electronics, EV motors, wind turbines, smartphones, and magnetic assemblies.

If U.S. mining operations begin capturing rare earth by-products at the source, the metal recycling industry could see meaningful shifts:

A Stronger Domestic Supply Chain

If U.S. mining can supply even part of America’s annual rare earth demand, recyclers would have more reliable domestic feedstock to work with. This reduces vulnerability to global supply shock from countries such as China, which currently dominates rare earth refining.

More Efficient Recycling Markets

Once more REEs are captured rather than discarded, recyclers will be able to:

  • Source more consistent volumes
  • Create standardized recovery processes
  • Lower per-unit processing costs

This stabilizes pricing and encourages investment in new recycling infrastructure.

Expansion of Domestic Processing Technologies

Recycling facilities could adopt separation and purification systems typically seen only in primary mining and refining. This would allow recyclers to move further up the value chain by producing battery-ready and magnet-grade materials instead of only recovered metals.

Economic & Strategic Benefits

A more complete U.S. recovery system both in mining and recycling could:

Benefit

Impact

Reduced reliance on foreign imports

Increased national security & supply stability

Lower waste and environmental impact

More responsible use of mined resources

Stronger industrial competitiveness

Supports EVs, electronics, renewable energy manufacturing

Job growth in recycling & processing

Skilled domestic workforce expansion

Benefit

-Reduced reliance on foreign imports

-Lower waste and environmental impact

-Stronger industrial competitiveness

-Job growth in recycling & processing

Impact

-Increased national security & supply stability

-More responsible use of mined resources

-Supports EVs, electronics, renewable energy manufacturing

-Skilled domestic workforce expansion

Rare earth metals are essential for:

  • EV motors
  • Solar panels
  • Wind turbine generators
  • Computer hard drives
  • Aircraft & defense technologies

The cleaner, stronger, and more resilient the U.S. supply chain becomes, the faster the country can scale renewable energy, transportation electrification, and advanced manufacturing.

Why Recovery & Recycling Together Is the Future

Mining alone cannot meet long-term demand, not without environmental and land-use consequences. Recycling alone cannot meet demand either, because product lifecycles are long and many devices are not yet at end-of-life. But together? By-product recovery + metals recycling = a sustainable domestic supply chain. We have already mined the metals. We simply need to keep them.

D Block Metals’ Role in the Circular Metal Economy

At D Block Metals, we specialize in recovering high-value metals from obsolete electronics and industrial waste, refining and processing strategic metals for reuse, and supporting organizations in sustainable material disposal and sourcing.

As the U.S. begins adopting by-product recovery at mining sites, the volume and consistency of rare earth-bearing material available to recyclers will increase and we are prepared to scale with it.
