  • How Is Graphite Extracted? Sciencing

    Apr 25, 20170183;32;Open pit mining involves extracting rock or minerals from an open pit or burrow. Open pit methods are used when the ore is close to the earth and the surface material covering the deposit is thin. Quarrying is a form of surface mining employed to obtain graphite by breaking the rocks either by drilling or by using dynamite explosives to cut open the rocks and compressed air or water to split it.

  • Coal Mining and Processing Energy Trends Insider

    Coal Mining and Processing. Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top soil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.
