Facts
Interesting Facts
  • 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.
  
  • Vanadium is a highly reactive metal, hence it is not found free in nature.
  • Vanadium can be found in almost 65 different types of minerals.

Uses
Uses & Benefits
  • 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.
  
  • Its ally with steel is used very tough and hence it is used in armor plates, axles, piston rods, tools and crankshafts.
  • Its oxide is used as pigments for glass and ceramics.
