froth flotation is the use of the physical and chemical properties of the surface of the ore the use of chemical separation of useful ore in the process of froth flotation useful minerals are separated by floating them in the foams and the way of keeping gangue minerals in the pulp is called positive flotation while the way of floating gangue minerals in the foam is called reverse flotation.
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.
