Facts
Interesting Facts
  • Major mining countries of Uranium include Russia, Australia, Namibia, Canada and Niger and total 33% Uranium are mine in Kazakhstan.
  
  • Manganese is an essential trace element in all forms of life.
  • Manganese metal oxidizes very easily, but it does not fuse that easily.

Uses
Uses & Benefits
  • The main use of this metal include nuclear fuel which is used to generate electricity yin nuclear power stations.
  • Synthetic elements like transuranium are made from Uranium metal.
  
  • This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
  • Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
