Mining Mining Surface mining It has been estimated that more than twothirds of the worlds yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.
