froth flotation of light rare earths

Rare Earth Flotation Fundamentals: A Review

2017-12-14  O) has also been found as source of domestic rare earths (Cui 2015). 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
