Mining and Refining – Process - World Aluminium

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. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of ...
