In a flotation cell, entrainment occurs simultaneously along with true flotation. Unlike true flotation, entrainment is not chemically selective and it occurs without a direct attachment of particles to bubbles. Therefore, both valuable and gangue minerals experience entrainment. Fig. 1 describes the mass transfer throughout a flotation cell.
