Common Questions About Froth Flotation Process …
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.
