Facts

Interesting Facts
  • Platinum is the rarest metal from the Precious metal categories..
  • Commercially Platinum is produced as a byproduct in ores of nickel.
  
  • Neodymium is not found free in nature, hence it is not a native metal.
  • Neodymium metal found in minerals like Monazite and Bastnaesite.
