Bauxite is collected from the ground in an open-pit mining operation. It doesn't sit very deeply in the earth's crust, so some energy can be saved on drilling. However, to recover all the aluminum in an area, swaths of land must be bull-dozed to reveal the dirt and ore underneath. Once collected, the bauxite ore has to be refined.

Global Bauxite Mining to 2020. Bauxite is a rock made up of laterite soil, which is the primary raw material used in the production of alumina and aluminium metal. It is mainly found in tropical areas, where intense decomposition aids in its generation. Generally, bauxite is found in a thin layer, typically 2-5 meters close to the surface.

Bauxite forms by the weathering of aluminum-rich and silica-poor rocks in hot, humid, climates, at places with good drainage. Under the proper conditions, weathering disintegrates the aluminium silicate minerals, and dissolves and removes the silica, creating bauxite. The mined US bauxite deposits have all been in the southeastern United States.

Bauxite is mined by surface methods (open-cut mining) in which the topsoil and overburden are removed by bulldozers and scrapers. The topsoil is then stored and later used for revegetating and restoring the area after mining is completed. The underlying bauxite is mined by front-end loaders, power shovels or hydraulic excavators.
