Kinetic study in selective reduction of limonitic and saprolitic nickel ...
2022.11.22 La saprolite et la limonite ont un comportement différent dans le procédé de réduction carbothermique en raison des différences dans leurs structures atomiques. Ce travail examine l’étude cinétique de ces deux types différents de minerais de nickel latéritiques.
