    Surfacemining– strip, open pit, mountaintop removal

    Surfaceminingis a form ofminingin which the soil and the rock covering the mineral deposits are removed. It is the other way of undergroundmining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surfaceminingis basically employed when deposits of commercially viable minerals or rock are found closer to the surface ...

    There are four mainminingmethods: underground, open surface (pit), placer, and in-situmining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placerminingis used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
