  • TECHNICAL NOTES 9 FLOTATION - Mineral Tech

    or less stable and mobile layer of froth will persist on the surface of the slurry which will gather and recover a proportion of the adhering mineral particles. 8.1 A Kinetic Approach to Flotation Modeling Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process.

  • What is the role of depressant in froth floatation process?

    In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.

  • Recovering Gold through the Froth Flotation Process .

    Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.

  • flotation – Mining Mill Operator Training

    Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.

  • 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.
