What Are Column Flotation Cells?

2019-2-6 · 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 launder for capturing.

1 Froth Flotation – Fundamental Principles

2009-8-27 · The basis of froth flotation is the difference in wettabilities of different minerals. Particles range from those that are easily wettable by water (hydrophilic) to those that are water-repellent (hydrophobic). If a mixture of hydrophobic and hydrophilic particles are suspended in water, and air is bubbled through the suspension, then the hydrophobic particles will tend to attach to the air bubbles and float to the surface, as shown in Figure 3. The froth layer that forms on the surface will then be heavily loaded with they hydrophobic mineral, and can be removed as a separated product. The hydrophilic particles will have much less tendency to attach to air bubbles, and so it will
