Interesting Facts
- Neodymium is not found free in nature, hence it is not a native metal.
- Neodymium metal found in minerals like Monazite and Bastnaesite.
- Galena mineral contains almost 87% of Lead metal in it, Galena is sulfide mineral.
- The best available source of Lead metal today is by recycling automobile batteries.

Uses & Benefits
- Neodymium-Iron-boron alloy is used to make permanent magnets.
- It is used in microphones, Mp3 player, loudspeakers, mobile phones, etc.
- It is also used in insecticides, hair dyes and as an anti-knocking additive for petrol. But all these are banned by the government as Lead metal is known for detrimental to health.
