These differ from one another in the mine geometries created, the techniques used, and the minerals produced. Open-pit mining often but not always results in a large hole, or pit, being formed in the process of extracting a mineral. It can also result in a portion of a hilltop being removed. In strip mining a long, narrow strip of mineral is uncovered
