Feb , what are flotation cells flotation cells are used to separate minerals in a liquid solid suspension of desired and undesired materials the desired solids are separated by making them hydrophobic, so they will attach to air bubbles that are created with either air injection or agitation along with a reagent these solids flow over into a
