Extraction de l'uranium — Wikipédia

Le minerai d'uranium est extrait selon quatre techniques, dites conventionnelles : • l'exploitation en galerie souterraine : le minerai est atteint grâce à des galeries à l'instar des mines de charbon. En 1990, 55 % de la production mondiale provenait de mines souterraines, mais cette technique a diminué de façon spectaculaire pour ne représenter plus que 33 % en 1999 et 28 % en 2010 po
