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 frother, is normally added to promote the formation of small bubbles.

Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.

Jul 06, 2017 Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity (how much they are attracted to water) and is enhanced through the use of surfactants. Surfactants are chemicals that act as a wetting agent to attach to particles and increase their attractiveness to air bubbles.

of flotation is to have the desired mineral in solution attach to an air or nitrogen bubble and form a froth layer, which is periodically scraped off and collected. Bastnaesite is a hydrophilic mineral, so collectors are required to make the mineral hydrophobic. The hydrophobic minerals can then attach to the air bubbles and form a froth.
