Mining and Refining Process

The bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers. Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina refineries, which are generally located close to bauxite

Bauxite The Aluminum Association

When the land is cleared prior to mining, the topsoil is stored so it can be replaced during rehabilitation. During the strip-mining process, bauxite is broken up and taken out of the mine to an alumina refinery. Once mining is complete, the topsoil is replaced and the area undergoes a restoration process.

Bauxite mining in the United States Wikipedia

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.
