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.

The methods used in mining bauxite differ somewhat in different countries and with different types of deposits. In deposits occurring in the form of extensive surface blankets or in beds and lenses interlayered with unconsolidated sediments, such as are being mined in Arkansas and in northern South America, quarrying is a common method of mining.
