Mining and mineral processing | The lithosphere | Siyavula

Surface mining (open pit mining) This type of mining takes place from the surface of the Earth. In open pit mining, the topsoil is removed first and placed on the side of a trench. Then the surface layers of rock are removed to expose the deeper, valuable mineral layers. The valuable rocks are then blasted into smaller rocks using explosives.

Equipment Selection for Surface Mining: A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
