Ans : Froth flotation makes it easier to obtain valuable minerals, like copper and lead-bearing minerals, from rocks. Along with mechanised mining, it has made it possible to make money by extracting valuable metals from much less valuable ore than before. Ans :A flotation cell is a piece of equipment used to froth float ore in water.

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
