L'extraction de la bauxite, principal minerai à partir duquel est produit l'aluminium, comporte non seulement des risques importants pour l'environnement mais elle est aussi très énergivore. Les « boues rouges » issues de la transformation de bauxite en alumine, puis en aluminium, contiennent des métaux lourds, des hydrocarbures de fluor ...
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 ...
