Open-Pit Mining

Open-pit mining is a surface-mining operation, in which rocks or minerals are extracted from the Earth by creating an open hole, or pit, in the Earth's surface. These pits are generally 1km deep beneath the Earth's surface, and are used to exploit low-grade ore bodies. This type of mining is used only when the minerals to be extracted are ...
