  • Rare Earth Flotation Fundamentals: A Review

    Rare Earth Flotation Review Literature on the flotation of rare earth oxide minerals is a relatively limited. This is especially true with regard to fundamental flotation research, although, as the demand for rare earths continues to grow, the amount of research in the field is increasing rapidly.
