Future Prospects

Plans for such collaboration is already being considered. For example, the Environmental Protection Agency might work with the United Nations to fund for research on electronic recycling ("Rare Earth Elements"). Research has already improved existing recycling techniques; bioleaching is used to extract precious metals from rare earth magnets.

RARE EARTH ELEMENTS: A REVIEW OF PRODUCTION, …

Rare earth elements (REEs) are a group of 15 chemical elements in the periodic table, specifically the lanthanides. Two other elements, scandium and yttrium, have a similar physiochemistry to the lanthanides, are commonly found in the same mineral assemblages, and are often referred to as REEs. REEs have not been mined in the United States for about 20 years, and prior to that time, the amount ...

What if we ran out of minerals? | HowStuffWorks

Minerals make up most of what we use to build, manufacture and stand on — including rocks and soil — so if we really ran out of minerals, we'd all be scrambling for a spot on the planet's shrunken surface areas.. But if you were worried about running out of a single mineral important for industry, then you probably can breathe easy. Most of the minerals we use a lot are very abundant.
