California's Mountain Pass Mine started as a disappointment. Prospectors looking for uranium eyed the site with high hopes, but the ore samples that they sent to the U.S. Geological Survey proved poor in the radioactive metal. The site turned out to be rich, however, in rare-earth elements. Valued today for their utility in high-tech ...

Phoenix Tailings is the first company to actually process usable rare earth metals here in the US and work towards a steady rare earth supply chain. "In the 1980s, earth metal processing left the United States and Western Europe, relocating to developing countries with lower labour costs and fewer environmental regulations," said Myers.

What Smith sees as the new bull market for rare earths comes a decade after the market dropped sharply after hitting record highs. Smith said that there are fundamental differences between the rally he sees today and the one 10 years ago. Smith explained that 10 years ago the rally in rare earths was driven by geopolitical factors as China held ...
In trying to build more rare earth capacity, the US government has offered millions in grants for mining companies to expand their operations. However, most of the concentrates obtained through ...

The rare-earth-rich solution collected on the other side is further processed to yield rare earth oxides at purities exceeding 99.5%. That's remarkable considering that typically, 70% of a ...
The authors note the irony that precious gems and other minerals highly valued by humankind — including so-called "rare earth" minerals required to make electronics — don't meet the definition of rare as far as Planet Earth is concerned. ... (see endnotes), fewer than 100 of which make up 99% of Earth's crust, with a handful of ...
Major automakers are seeking new ways to make electric vehicle (EV) motors that depend less on rare earth minerals. China controls most mining and processing of a group of 17 metals known as rare ...
