Froth flotation is a physicochemical separation technique that exploits the difference in the surface wettability of mineral particles (Wills and Finch, 2016).From a heterogeneous mixture of solids, hydrophobic particles are made to attach to gas bubbles and subsequently carried to the froth phase and recovered as a froth product (typically …
Froth Flotation Process
Froth Flotation is a very important process in the field of mineral processing which is utilized for the purpose of extraction of minerals from Ore. It is a part of surface chemistry in which we selectively separate the minerals from the unwanted material. This process is used in a variety of industries and is very crucial in each one of them.

1 Froth Flotation – Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
Flotation
The Inspiration Copper Co. uses flotation as the prime process, and its 800 tons per section is treated by 24 roughing-cells and 4 cleaners. In this case the cells are run in series, the primary cells treating the original feed and the secondary cells re-treating only the slime from the primary tailing after the sand has been removed.

Agitated cells are commonly used. Flotation columns are also practical, as their footprint is small and a proper height will allow for effective multi-stages separation (Moon and Sirois, 1983), akin to the operation of a distillation column with counter-current flow of coal- carrying bubbles up and ash-laden water down. Addition of wash water ...
