Froth flotation is a process for selectively separating 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.
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.

Froth flotation is the most widely used separation process in modern paper mills. During the last 10 years, the development of flotation de-inking cells has been pursued more aggressively than the technologies of any other segment of the pulp and paper industry.
Flotation Process . Typically three different types of chemicals are used in the froth flotation process collector frother and modifier First the collector is added to the iron ore slurry to selectively coat the iron oxide particles making the surface hydrophobic The slurry then goes to a
Dec 20, 2018 Cyanidation of froth flotation flotation concentrate A small amount of concentrate is obtained from gold-silver quartz vein sulfide ore by flotation, and then cyanide treatment is carried out. Compared with the whole slime cyanidation process, the froth flotation method concentrate process has the advantages of no fine grinding of all ores, saving power
Flotation involves adding process reagents to flotation cells. This encourages the attachment of desired product to fine air bubbles. The bubbles surface and paddles scoop the froth off of the top of the cell. Product recovery rates in flotation are key to maximizing a mills production.
