  • Froth Flotation an overview ScienceDirect Topics

    Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in Colloid and Interface Science, 2005. Related terms: Adsorption; Agglomeration; Chlorine

  • 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.

  • Flotation Froth an overview ScienceDirect Topics

    The use of froth in flotation is twofold. Firstly, froth is used to convey the mineral laden bubbles from the froth-pulp interface to the concentrate launder. Secondly, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp (Figure 13). The froth cleaning process can be improved by applying spraying (wash) water upon the surface or inside the upper layer of the froth.
