U.S. discards critical minerals amid mining operations

U.S. discards critical minerals it mines, study finds.

Why it matters

  • U.S. mines enough critical minerals annually but discards them as waste.
  • Recovery could reduce reliance on imports and improve sustainability.

By the numbers

  • Study examined 70 elements used in tech, defense, and energy.
  • Recovering <10% of cobalt and <1% of germanium could meet U.S. needs.

The big picture

  • Critical minerals discarded as byproducts in mining operations.
  • Policy and research needed to make recovery economically feasible.

What they're saying

  • Refining costly and environmentally challenging; future potential in landfill mining.

Caveats

  • Economic feasibility of recovery remains a hurdle.
  • Requires detailed analyses and policy incentives.

What’s next

  • Research on recovery technologies and mineral-specific solutions.
  • Policies to incentivize investment in recovery infrastructure.
