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.
