The U.S. was 100% net import reliant on rare-earth elements in 2018, importing an estimated 11,130 metric tons of compounds and metals valued at $160 million. Eighty percent of those imports were sourced from China, according to the U.S. Geological Survey.
Are there rare earth minerals in the US?
Only one rare earth mine, at Mountain Pass, CA, has ever been developed in the United States. The cost of putting together a REE mine can cost up to a half a billion dollars or more.
Heres a look at the 10 countries that mined the most rare earths in 2020, as per the latest data from US Geological Survey.China. Mine production: 140,000 MT. United States.

Where do rare earth minerals come from?
Rare-earth ore deposits are found all over the world. The major ores are in China, the United States, Australia, and Russia, while other viable ore bodies are found in Canada, India, South Africa, and southeast Asia.
Sharks possess electrical sensors, called the ampullae of Lorenzini, that look like tiny freckles on their snouts. In 2004, Eric Stroud found that magnets repel sharks, possibly by overwhelming their electrical sensors, and now he says his team has found that some rare earth metals appear to have the same effect.
