MONAZITE ORE COULD SUPPLY EV MOTOR MAGNET METALS, IF THE THORIUM WASTE CAN BE HANDLED

spectrum.ieee.org19 min read

Summary from the TLDR Hardware newsletter

Monazite ore is 45 to 70 percent rare earths by weight and carries all four elements motor magnets need (neodymium, praseodymium, dysprosium, and terbium), making it a leading path around China's roughly 90 percent market share. The catch is thorium, whose waste must be stored indefinitely. Energy Fuels already produces neodymium-praseodymium oxide plus pilot dysprosium and terbium at its Utah mill, while Saskatchewan's government-backed plant has produced little after six years and over CA$100 million.
