Rare Earth Flotation Fundamentals: A Review - AJER

Froth flotation relies on the separation of these minerals based on differences in their surface properties. Unfortunately, this is where the difficulty in rare earth flotation lies, i.e. both the desired and gangue minerals are oxides. Thus, efficient separation of one oxide from another can prove extremely complex.
