However, column flotation is not efficient for treating fine coal containing significant amounts of mixedphase particles. Fortunately, enhanced gravity separation has proved to have the ability to treat the mixedphased particles more effectively. A disadvantage of gravity separation is that ultrafine clay particles are not easily rejected.
