Scientists may have discovered a new source of rare earth

Rare earth elements make up a minuscule portion of phosphate rock. But the mining and fertilizer industries churn out millions of tons of phosphogypsum, so the trace amounts of these metals pile up. Around 100,000 tons of rare earth elements get dumped alongside the phosphogypsum discarded by the fertilizer industry.
