How is Lead Obtained?

  • Lead is obtained from a method with many other metals
      1. Ore is heated in air (converts the ore to lead oxide PbO2)
      2. PbO2 is heated with pure carbon
      3. The carbon takes oxygen away from PbO2
      4. Leaves pure lead
  • Lead can be further purified electrolytically (passing an electric current through a compound)
  • Lead can also be obtained from recycling
      1. Process in which a material is retrieved from a product that is no longer used
      2. Extracted
