Entrainment of Gangue Minerals in Froth Flotation

Aug 31, · Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a twostep process, one at the upper layer of the pulp to the flotation froth, and the other from froth to the
