    Flotation Froth - an overview | ScienceDirect Topics

    The most widely accepted method for upgrading ultrafine coal is froth flotation. Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig. 17). A chemical reagent, called a

    Abstract. The upgrading of phosphate ores using froth flotation method has been practiced for at least 65 years.Extensive research work has been carried out in the last 25 years, on various phosphate-containing ores.Despite of extensive research and industrial experience, there are some challenges remaining in particular in beneficiation of siliceous, calcite, and heavy mineral containing
