Copper Mining and Processing Life Cycle of a MineSuperfund

Surface mining, which includes strip mining, openpit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the predevelopment steps are complete. Underground mining uses shafts and tunnels to access deeplyburied mineral deposits, while the overlying rock is left in place.
