Mining Without New Holes in the Ground
One of the more overlooked developments in this shift is how much of the new supply is coming from materials that already exist above ground.
Research conducted by Georgia Tech on
byproduct recovery shows that using coal ash, kaolin tailings, and mine waste allows one to recover rare earths without additional mining.
11 million tons
of potentially recoverable rare earths could be held in U.S. coal ash alone.
Coal ash could potentially hold 11 million tons of recoverable rare earths in the US alone, meaning that it has
almost eight times the current amount of rare elements reserves on land, according to University of Texas
research.
This new method of obtaining rare elements should be viewed positively from an environmental perspective and is also beneficial to businesses that rely on the availability of rare materials in the future. As the need for permits becomes much lower with such products, new materials can be made available much sooner than with traditional mining.
This approach matters for businesses beyond its environmental appeal. Projects with a smaller land footprint typically face fewer permitting delays and less regulatory friction, which means new supply can come online faster than it would through conventional mining.
For companies trying to plan around future material availability, that speed is a meaningful advantage.
