Bingham Canyon Copper Mine

TIA Daily reader Jay Palmer writes:

"I see that you do not have any items for Utah in your sightseer's guide to human achievements. To correct this deficiency, I think that the Bingham Canyon copper mine belongs on the list. This open-pit copper mine is now 100 years old, and at 2-1/2 miles wide, is the largest man-made excavation in the world."

"The mine has produced a total of over 15 million tons of copper to date, as well as large quantities of by-product molybdenum, silver and gold. During World War II, this one mine produced 1/3 of the copper used by the Allies; the mine has been the site of some important innovation in the mining industry. (The source of the latter information is an article in American Heritage of Invention & Technology, vol 16, number 3. It's a good article on the mine and the men who developed it, but marred by the author's groveling to environmentalism.)"

"Standing at the overlook within the Bingham Canyon Mine, you can see, hear, and feel the breathtaking and awesome magnitude of the largest man-made excavation on earth. While you watch the action in the mine, a descriptive narration recorded in several languages explains the operations."

"From the overlook, you can watch 240 and 320 ton capacity haulage trucks deliver copper ore to the in-pit crusher, where the material is reduced to the size of soccer balls before being loaded onto a five-mile conveyor that carries the ore to the Copperton Concentrator."
