Copper Mining and Processing: Resources and Glossary

heap leaching: Generally, an industrial mining process in which a valuable metal is extracted from a heap, or pile, of crushed ore For copper oxide ore, heap leaching is the first stage in the process of hydrometallurgy, in which a chemical solution is applied to a heap of crushed ore, through which it percolates, dissolving the copper

Copper Mining and Processing: Life Cycle of a Mine |

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 This type of mining is usually more expensive and complex, and requires a lot of additional planning for convenience and safety Solution mining

Copper Mining and Processing: Background | Superfund
