Solved Problem 3. In froth flotation, air is bubbled ...

In froth flotation, air is bubbled through an aqueous solution or slurry to which a foaming agent (soap) has been added. The air-soap bubbles carry finely dispersed solids and hydrophobic materials such as grease and oil to the surface where they can be skimmed off in the foam. In this example, an ore-containing slurry is to be processed in a

Flotation Froth - an overview | ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
