    FROTH FLOTATION known as liberation, which then has to be separated from the desired mineral. The ore is ground into a fine powder and mixed with water to form a slurry, the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical. The particular chemical depends on which mineral is being refined. As an example, pine oil is used to extract copper.

  • Flotation Reagent

    Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).

  • Froth floatation process

     · Bubbles tend to collapse when the liquid that makes up the walls drains away and the walls weaken. The walls can be strengthened by choice of surfactant (and addition rate) and by adding thickeners like water-soluble gums (e.g., xanthan) or polymers or glycerol (also for children''s bubbles).

     · Flotation relies on differences in surface properties of different minerals to achieve separation. The study of these surface properties is known as surface chemistry. In flotation, it is necessary to understand the surface properties of minerals. Most importantly, surfaces can be either hydrophilic (water loving), or hydrophobic (water fearing).

    Froth Drainage. The use of froth in flotation is twofold. First, froth is used to convey the mineral-laden bubbles from the froth–pulp interface to the concentrate launder. Second, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp ( Figure 13).
