Rare Earth Element Mining for Electronics (Neodymium, Dysprosium — Radioactive Thorium, Tailings Contamination) — household safety profile

High risk

Rare earth elements (REEs) — neodymium, dysprosium, lanthanum, cerium, and 13 others — are essential for electronics: neodymium magnets in hard drives, speakers, earbuds, and EV motors; europium and terbium in display phosphors; lanthanum in camera lenses.

What is this product?

Rare earth elements (REEs) — neodymium, dysprosium, lanthanum, cerium, and 13 others — are essential for electronics: neodymium magnets in hard drives, speakers, earbuds, and EV motors; europium and terbium in display phosphors; lanthanum in camera lenses. Global REE production: 350,000 tonnes in 2023, with China controlling 60% of mining and 90% of processing. REE ores (monazite, bastnaesite) naturally contain radioactive thorium (Th-232) and uranium (U-238) — mining and processing concentrate these radionuclides in tailings. Bayan Obo (Inner Mongolia), the world's largest REE mine, has a tailings lake containing an estimated 200,000 tonnes of radioactive thorium. Lynas Malaysia refinery (world's largest outside China) generated controversy over radioactive waste disposal — communities reported elevated thorium in local waterways. In-situ leaching of ionic clay REE deposits (southern China) uses ammonium sulfate — contaminating groundwater and causing landslides. REE processing requires harsh acid/alkali steps (HCl, NaOH, HF) generating toxic wastewater. A single wind turbine uses 600 lbs of REEs; an EV motor uses 2-5 lbs of neodymium.
