Histoire des mines de bauxite — Wikipédia
L'Histoire des mines de bauxite a vu la production mondiale dopée par celle du produit fabriqué en aval, l'aluminium, même si les gisements sont souvent éloignés et difficiles à identifier. Jusqu'aux années 1950, l'extraction de ce minerai était réservé à un nombre limité de producteurs, essentiellement en Europe et aux États-Unis, mais leur nombre a fortement augmenté lorsque de,bauxite - Traduction française – Linguee,Although setting up the bauxite mining site started a year ago, plans for this project have been in place for over four years. viettan.org. viettan.org .
