    Lead is one of the few elements which can be found in nature in pure form. There is a sample of elemental lead with pyrochroite is displayed in the Smithsonian Museum of Natural History. This large sample is about 18x30 cm and is from Langban Mine, Filipstad, Varmland, Sweden.

    Metallic lead does occur in nature, but it is rare. Lead is usually found in ore with zinc, silver and (most abundantly) copper, and is extracted together with these metals.
