Episode notes
Rare Earth Chemistry and Naming
- Rare earth elements comprise 15 to 17 chemically similar elements mostly found together in deposits.
- The term "rare earths" is misleading; they are mostly lanthanides grouped due to similar chemistry and occurrence.
China's Rare Earth Export Controls
- China controls the heavy rare earths and export controls target the rarest seven elements with dual-use military and civilian applications.
- Supply concentration and China's dominance give them leverage in these critical heavy rare earths like dysprosium and terbium.
Rare Earth Supply Concentration
- Only five mines produce about 85% of global rare earth supply, mostly light rare earths.
- Heavy rare earths demand is met mainly by ionic clay mining, which is less traditional and environmentally challenging.
