Facts
Interesting Facts
  • Copper rarely found in its pure form in nature.
  • Copper Sulfate is mostly used in agricultural poison and as an algicide in water purification system.
  
  • 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.

Uses
Uses & Benefits
  • It is use for coinage and bullion.
  • Most of copper element is used in manufacturing electrical and electronic equipments such as wirings and components. It is also used in construction and industrial machine.
  
  • 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.
