Facts

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