What is a Flotation separator?

Flotation, sometimes known as froth flotation, arose in the realm of mineral processing. For many years, various particulate solids other than minerals have been extracted from water using this effective gravity separation method, which is based on the idea of using rising gas bubbles as the transport medium, with the attachment of bubbles to particles transferring the solids from the body of water to the surface. Flotation, as opposed to settling, is a solid–liquid separation process that is used with particles that have a lower density than the liquid they are in. The treatment of water and wastewater is one of the most common flotation applications. It is a common concentration method for selectively separating hydrophobic components from hydrophilic waste gangue. In a more straightforward sense, froth flotation is one of the most widely used mineral beneficiation techniques.

Froth flotation is a process for separating commercially essential minerals from contaminants and other minerals in ore/mineral beneficiation by collecting them on the surface of a froth layer.

Principle of flotation separator

Flotation is a versatile process for physically separating particles in a mineral/water slurry based on differences in air bubbles' propensity to preferentially attach to specific mineral surfaces. The particles are then transported to the surface with connected air bubbles. The particles that have not been thoroughly wetted remain in the liquid phase. Since, chemical additives can be used, flotation can be used for a wide range of separations treatments that selectively modify mineral surfaces to give them the characteristics needed for the separation.

They are hydraulically operated, allowing for efficient oil recovery from water streams while maintaining total process containment. The fully enclosed flotation process ensures operator and environmental safety. They use microscopic gas bubbles (usually 50 microns in diameter) to separate and recover oil and fine solid particles from water. Oil and tiny solid particles in the water stream cling to these gas bubbles and float to the surface to be skimmed off. By recirculating a side stream of clean water from the exit, the gas bubbles are distributed into the incoming water flow. Gas is induced into the recycle water due to the high velocity.

What are the methods of Flotation separator?

1: True flotation - This process is crucial and important since it is just this step that determines the extraction of pure water, while the other two processes defines the separation efficiency between the water and the gangue.

2: Entrainment - In this process, air bubbles are transported through liquid water, causing froth to form, resulting in the formation of air bubbles.

3: Aggregation - The froth traps the particles in this step.

What are the benefits of Flotation separator?

1: Chemical consumption is minimal or non-existent- Here the chemicals get easily removed because they get drowned easily.

2: Low manpower for operations and maintenance- It is a natural process where denser particles get settle down and hence not much manpower is needed.

3: Oil removal to a minimum – Through the skimmer process after flotation oil can be easily removed so overall it is a very important process.

4: Fine solids removal – All the solids being denser can easily be removed.

Conclusion

The term "floatation" refers to a group of operations known as "adsorptive bubble methods." Separation methods are divided into foaming and nonfoaming categories. Surfactants must be added to foaming processes in order to create a relatively stable foam or froth, which subsequently acts as a carrier fluid during particle removal. Solid hydrophobicity, bubble to particle size ratio, and the amount of turbulence in the fluid are the most essential properties in determining the success of a flotation process.
