Apr 01, 2018 After grinding the raw ore to a specified particle size, the rare earth mineral particles agglomerated during flotation to form aggregates due to the flotation collector. These hydrophobic aggregates were collected within the flotation froth fraction, and most of the gangue remained in the bulk and were treated as tailings.
