Flotation is a widely used process for separating valuable minerals from their ores. The method relies on the ability of certain minerals to attach to air bubbles, while other materials remain submerged in water. By adding specific chemicals known as reagents, the process can be optimized to improve the recovery and grade of valuable minerals.

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.
