What is it?
Neodymium's near-twin, so alike that magnet makers usually do not bother separating the two and sell them together as didymium.
Why does it matter?
Pr substitutes directly for Nd in magnet alloy, which effectively enlarges the magnet-metal pool. It also colours welding goggles and glass yellow-green.

Where it comes from in the rock
All ore minerals →These are the minerals that actually carry praseodymium. A deposit is only an orebody if one of them is concentrated enough to pay for digging it up.
Bastnäsite
The world's principal light rare-earth mineral, mined from carbonatites. Low in thorium, which makes it easier to…
Monazite
A rare-earth phosphate found in heavy mineral sands. Carries thorium, so it is radioactive enough to be regulated.
