    Good flotation frothers have branched hydrocarbon radicals and form loosely packed gaseous films at the liquid/gas interface. Their hydrophile lipophile properties must be properly balanced and for most good frothers the HLB values are close to 6. This allows them to co operate actively with the adsorbed collector in the moment of particle to bubble attachment.

    Froth flotation

    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.
