Entre la roche et le produit

Traitement et affinage

L'exploitation minière n'est que la première étape, et rarement la plus difficile. Le goulet d'étranglement dans presque toute chaîne d'approvisionnement en matières critiques n'est pas celui qui extrait le minerai — c'est celui qui est capable de le transformer en quelque chose d'utilisable.
