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