Facts
Interesting Facts
  • The main source of Cobalt is as a by-product of copper and nickel metal mining.
  • Cobalt metal can be obtained from other elements like Oxygen, Sulfur and Arsenic.
  • It s also used in electroplating process as it exhibits anti cession properties.
  
  • The only metal which burns in Nitrogen is Titanium.
  • Titanium is also known as corrosion resistant metal.
