An opencast or open pit mine is used to extract valuable deposits close to the earth''s surface. Here the fragmentation, loading, materials handling and production control require heavy equipment. To maximise extraction volume and minimise the space for infrastructure, slopes within open pit mines can be steep.

Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
The most common approach to extracting metalbearing ore from a porphyry copper deposit is by openpit mining, although such mines also typically include some underground activities. This astronaut photograph illustrates three openpit mines located westnorthwest of the town of Green Valley, Arizona.
