Surface Mining Process | Steps In The Mining Process & Surface
Surface mining is a mining process where the rocks and soil overlying the mineral deposits are removed. It is often the preferred form of mining for most mining companies. This is because removing the terrain surface, or overburden, to access the mineral beneath is often more cost-effective than gouging tunnels and subterranean shafts to access

Iron Ore Mining – The process of iron ore mining %y
Iron ore mining is the process of extracting iron from its natural form, which is found in rocks and minerals. The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that there is no waterlogging or runoff. The next step is to drill holes into the rock, so that explosives can
