Types of Flotation Cells. The world of mineral processing is diverse, and so are the types of flotation cell types. From the robust mechanical flotation cell to the efficient column cell flotation, each type serves a specific purpose. Mechanical cells use a mechanical agitator to mix the ore pulp and introduce air, creating bubbles.
