Common Questions About Froth Flotation Process Technology - Mining-pedia

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 is called reverse flotation.>

A flotation model has been validated against the survey data obtained from a copper rougher flotation circuit with a circulating load. The model was developed using the hydrophobic force as a kinetic parameter, which made it possible to use the contact angles of the free and composite particles as input parameters so that the model can predict both recoveries and grades.
