Copper made from the Bingham Canyon Mine adorns the Capitol's dome -- a feature that provided much of the building's majestic beauty. The dome is turning green, rather than bright and shiny like a penny, because of oxidation, the process of the copper being exposed to the elements. Modern life is very dependent on copper -- a major Utah export -- because it is an important component in everything from electronics to plumbing and vehicles to household appliances. |
