  Extracting Lead Materials from Ore

  Extracting Lead Materials from Ore. Lead is a dense soft low melting metal. Lead is the densest common metal except for gold and this quality makes it effective in sound barriers and as a shield against X rays.Lead resists corrosion by water so it makes a long lasting roofing material.. Only about half of the lead materials used today are produced from mining the rest
