What type of mine is the largest?



  1. 0 Votes

    Open pit mines seem to be the answer: these are giant holes dug in the ground to extract minerals. The biggest one is the Hull Rust mine near Hibbing, Minnesota, which is five miles long, two miles wide, and 535 feet deep. The deepest mine is the Bingham Canyon Mine, near Salt Lake City, which is 0.75 miles deep.

    Note that the Hull Rust mine is 535 FEET deep, not miles; it is one of the largest iron mines. The largest open-pit mine of any type in the world is Chuquicamata, Chile.
