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.
