Some challenges associated with gravity separation of the Bayan Obo ore are that gangue minerals ( barite) have similar specific gravities to the desired rare earth minerals and report to the concentrate stream. In addition, gravity separation is ineffective at separating very fine particles resulting in large losses of rare earths (Ming, 1993
