    The reagents provide an attraction between the surface of the copper minerals and the air bubbles. As the bubbles rise to the surface, they carry the copper minerals with them, leaving gangue minerals in the cell to be discarded as tailings. Collection of the froth from the surface of the flotation cell yields a copper concentrate.
