The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.

In the froth flotation method, depressant are used to separate two ores. In case of separation of ores such as and , a chemical compound called sodium cyanide with chemical formula is used. The sodium cyanide reacts with and forms and settles at the bottom. The other ore forms froth and remains at the top and later it is separated. Learn more ...
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.

Film-flotation, as exemplified in the Macquisten and in the “Wood machines, does not seem to have the same wide application as does froth-flotation; hence little need be said about them. FILM-FLOTATION. Macquisten tubes have such small capacity that a single tube is small enough for test-work on a few pounds of ore at a time (see Fig. 54).
