Draw the figure showing froth flotation process

Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering “system”, in that the various important parameters are highly inter-related, as shown in Figure 1

    Froth Flotation - an overview | ScienceDirect Topics

    The froth flotation process is commonly employed for the selective separation of a mineral species from a liquid–solid suspension of both valuable and unwanted gangue mineral particles. The valuable mineral species (which needs to be separated) is rendered hydrophobic by controlling its surface chemistry to provide the potential conditions for the attachment of the particles to air bubbles

    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

    Mar 27, 2016 The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which are floated are sulphides of

    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. It has been described as the single most important operation used for the recovery and upgrading of sulfide ores . The development of froth flotation
