    OverviewScience of flotationHistoryIndustriesPrinciple of operationFlotation equipmentMechanics of flotationChemicals of flotation

    To be effective on a given ore slurry, the collectors are chosen based upon their selective wetting of the types of particles to be separated. A good collector will adsorb, physically or chemically, with one of the types of particles. This provides the thermodynamic requirement for the particles to bind to the surface of a bubble. The wetting activity of a surfactant on a particle can be quantified by measuring the contact anglesthat the liquid/bubble interface makes with it. Another important measure for attachment of bubbl

    2009-08-27· 1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

  • Flotation Froth an overview ScienceDirect Topics

    Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

    The froth floatation device (10) includes a floatation column (12) partially filled with packing (24) which defines a large number of small flow passages extending in a circuitous pattern between the upper (14) and lower portions (16) of the column. A conditioned aqueous pulp of mineral ore, such as iron ore is introduced into the midzone of the column (12) through a pulp inlet (18).
