Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.
Flotation: The finely ground ore slurry is mixed with a flotation agent. The flotation agent type and amount will be selected according to the specific ore properties. Send the slurry into the flotation machine. The gold particles will be adsorbed on the air bubbles due to their unique properties, while other minerals will sink to the bottom.
