The problem with froth flotation is that certain gangue minerals have hydrophobic surfaces and undesirably float contaminating the precious mineral concentrate. To negate the hydrophobic minerals tendencies to float, depressants are used. They physically adsorb onto the surface of gangue minerals rendering the particles hydrophilic and "non-floatable".
