Gravity separation is used in mineral processing to separate minerals based on differences in their specific gravity . REEs are good candidates for the gravity separation method as they have relatively large specific gravities (4–7) and are typically associated with gangue minerals (primarily silicates) that is significantly less dense [1,12].
