Open Pit Copper Mine Tour

Excellent tour of an active open-pit mine and the milling complex where the copper-rich rocks are crushed and ground into fine sand, then added to water and special chemicals to create a slurry from which the copper is floated and skimmed from the top.

The discovery center has several educational videos fully explaining the process. Outside the center is a nice collection of vehicles and other mining equipment for viewing and photo ops.

Visit the exhibit center and video theater, then take a tour of the Asarco Mission Mine, the only open copper pit mine tour in Arizona. Stand at the edge of the open-pit mine, then view the copper mill in operation.

[Kirk Ehnisz, 02/11/2019]

The pit is two miles wide, and the observation point has classic binocular viewers. Claimed: "About six times the amount of earth moved to dig the Panama Canal has been mined here."
