Ore Reserves Suitable For Surface Mining

Mining Surface Mining Most suitable for large ore bodies and for low grade, disseminated ore bodies. Usually ore bodies are mined by a combination of surface and underground methods. Initial mining is by surface methods, but as mining deepens, the amount of waste to be removed increases soon economical to go underground.

Surface mining Wikipedia

"Strip mining" is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden).It is most commonly used to mine coal and lignite (brown coal).Strip mining is only practical when the ore body to be excavated is relatively near the surface.

Mining Surface mining Britannica

Mining Mining Surface mining: It has been estimated that more than two-thirds of the world’s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.

Surface Open-pit Mining Mineral Processing & Metallurgy

First of all let’s define what we mean with surface mining. Surface mining means the extraction of mineral deposits or coal reserves or stones of different kinds that are outcropping the earth’s surface or located at shallow depth from it. The economic depth for surface mining can range from 100 metres to 1 kilometre and over. The surface mining can be classified depending on the location

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
