Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

In recent years, developments in control strategy for banks of flotation cells have included process control based on mass pull. Mass pull, or the flowrate of solids reporting to the concentrate, is affected by changes in froth structure and stability which are in turn affected by changes in operating parameters such as air flowrate and froth depth.

Froth flotation Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral.

Figure 5. Copper flotation recovery by size (P. D Munro and S.E Munro (2015) derived from public data presented by Rio Tinto staff with Cadia East data added) The recovery of coarse copper sulphide composite particles via flotation is a function of inherent ore body mineralogical properties, surface chemistry and hydrodynamic conditions such as:

decompose in acidic environment and hence, results lower flotation recovery. Through proper control of pulp pH, one sulphide can be selectively floated from other. As regards other reagents used in sulphide flotation, depressants like sodium cyanide, ZnSO4, sodium meta bi-sulphite are common.

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.
