For copper sulfide ore, froth floatation is the first stage in the process of pyrometallurgy, in which air bubbles are introduced into a mixture of finely crushed ore with water and a chemical that aids attachment of the bubbles to the particles of copper, which are recovered as a floating froth.
Copper Mining and Processing: Life Cycle of a Mine
Surface mining, which includes strip mining, open-pit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the pre-development steps are complete. Underground mining uses shafts and tunnels to access deeply-buried mineral deposits, while the overlying rock is left in place.
