Bauxite mining - Murdoch University Research Repository
Bauxite mining is generally a relatively shallow, surface mining operation which removes a near surface 2-10 m layer of aluminium-rich material (Bardossy and Aleva 1990; Hickman et al. 1992). Bauxite develops over almost all types of geology but over one-third of the world's bauxite is formed on sedimentary rocks.
