· Posts about Mining written by Leticia Neves. Open pit mining: Commonly used for copper, iron, gold, diamonds and coal. Whenever the mineral to be exploited is gravel, sand, clay, and stone like limestone, granite, marble and slate, the pits are called used when the mineral is spread widely and evenly throughout a rock formation, or when the earth is unsuitable for tunneling.

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