Mining and Refining – Process World AluminiumBefore 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 postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.Alcoa BauxiteAlcoa has ownership in seven active bauxite mines globally and operates four of them, making us among the largest bauxite producers in the world.
