creating a froth for flotation. important to the flotation process is controlling the surface tension of the interface among the bubbles, the aqueous solution, and the hydrophobed particles. this is achieved by a combination of the design of the flotation machine (called a flotation cell) and the use of a second class of surfactants known as frothers.

frothing, also known as froth flotation, is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue. in its simplest form, froth flotation is a method whereby minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals, water and air bubbles.

Chapter 9: Collection And Attachment Of Particles By Air

9.1 introduction. froth flotation has a long history (over 100 years) of development and widespread applications. essentially, the process involves the attachment of finely dispersed hydrophobic particles to air bubbles to produce so-called three-phase froths on the surface of the flotation cell with the hydrophilic particles remaining dispersed in the suspension.

another flotation variant is electro-flotation. the two processes differ primarily in the way the gas bubbles are produced. in terms of the separation of solids from gases the phrase “dust separation” is also used. the solid phase may, on the one hand, be a usable material, on the other hand, it may be an unwanted material ( gas purification).
