Of these beneficiation methods, froth flotation is especially suited for dealing with low grade ores due to its higher selectivity compared with other enrichment processes. Froth flotation is a three-phase separation process in which a target mineral in an aqueous suspension is first rendered hydrophobic using “collectors”.

Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold.

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.
