Industrial flotation processes and applications: An understanding of the current state of industrial flotation processes and their applications is a valuable asset for anyone learning about flotation.

Air Flotation: This type of flotation uses air bubbles to separate the particles. The air bubbles are generated by aerators or blowers and the particles get attached to the air bubbles leading to the separation of particles from the aqueous solution.

Column Flotation: In this type of flotation, the feed slurry is introduced in the column and air is blown at high pressure through the base of the column leading to the formation of a froth layer. The particles attach to the froth layer leading to separation.

Foam Flotation: In this type of flotation, a froth is generated on top of the liquid by the addition of a foaming agent. The particles attach to the froth leading to the separation of the particles.

Dissolved Air Flotation: In this type of flotation, air is dissolved under high pressure in the aqueous solution. The dissolved air bubbles get attached to the particles leading to the formation of a froth layer and subsequent separation of the particles.

Electro Flotation: In this process, electrodes are placed in the slurry leading to the formation of bubbles which attract the particles leading to their separation from the aqueous solution.

Magnetic Flotation: This type of flotation is used for the separation of magnetic particles. A magnetic field is applied to the slurry leading to the separation of magnetic particles from non-magnetic particles.

Reverse Flotation: In this process, the valuable mineral particles are floated and the unwanted mineral particles are left behind leading to the separation of the particles.

Ion Flotation: In this type of flotation, the particles are separated based on their charge. Anionic or cationic surfactants are used to create an ionic charge on the surface of the particles leading to separation.

Oil Flotation: In this type of flotation, an oil layer is added to the slurry. The particles attach to the oil layer leading to the formation of a froth layer and subsequent separation.

Precipitate Flotation: In this type of flotation, chemical reagents are added to the slurry leading to the formation of a precipitate. The particles get attached to the precipitate leading to their separation from the aqueous solution.
