In the flotation process, air is bubbled through a suspension of fine iron ore in water to which a small quantity of flotation reagent is added. This reagent modifies the surface of either the iron oxide or the principal gangue component, normally silica, so that these particles attach themselves to the air bubbles and are carried to the surface, where they are removed as a froth.
