Used for near-surface, laterally continuous, bedded deposits such as coal, stratified ores such as iron ore, and surficial deposits (nickel laterite or bauxite). The pits are shallower that open-pit mines, and the overburden is hind-cast directly into adjacent mined out panels. Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation.

Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths. Open-cut mining means the surface extraction of clay, bauxite, sand, gravel, soil, shale or other materials for commercial purposes Operator means any person engaged in or controlling an open-cut mining or stream channel mined in this manner.

Environmental Inpact of Open PIT Mining Case of Bauxite Mining in Guinea -- A Review -- Mohamed Keita1 and Oumar Traore2 1Mining Department, China University of Mining and Geology, China. 2Geology Department , Odessa national university Mechnikova Ukraine. Abstract Bauxite is an important mineral for our society. Bauxite mining is becoming an Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and An open pit mine is typically excavated with a series of benches to reach greater depths. Open pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with front-end loaders and loaded onto dump trucks, which then transport the ore to a milling
