recovery (R) is the sum of the recovery by flotation (R float) and the recovery by entrainment (R ent). Water and suspended solids enter the froth in the wake of the air bubbles. Coarse particles are usually not present just below the froth due to sedimentation, and hence recovery by entrainment decreases as particle size increases.
