The separation of rare earth minerals from each other is difficult due to their similar atomic structures and surface characteristics. The effectiveness of flotation is primarily controlled by the surface properties of the minerals and is significantly related to the collector adsorption at the mineral-water interface.

Flotation is the most common beneficiation process used for separating minerals, but for rare earth minerals (REMs), performance can suffer due to the dilute nature of the rare earth elements. Furthermore, the REMs tend to possess smaller grain sizes, making the use of traditional flotation cells difficult if total liberation is needed. Consequently, improved …
