Rare Earths Are Actually Everywhere

Despite their name, rare earth elements are not actually rare at all. These seventeen metals are surprisingly common in the Earth's crust, often appearing in higher concentrations than silver or gold.

The term rare came about because these elements are extremely difficult to separate into pure metals. They are almost always found mixed together in complex ores, requiring intense chemical processes to isolate. Because they are so hard to extract and refine, they become expensive and strategically vital. You likely interact with them daily, as they are essential ingredients in your smartphone, high-tech magnets, and electric car batteries.
