    Flotation performance is highly dependent on particle size. For best performance, a particle size in the range of 20 to 100 m is required. Poor recovery of fine particles is typically associated with entrainment, whereas poor recovery of coarse particles is associated with inertial forces that prevent the large particles from being recovered.
