    Sep 29, 2003· Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent and dissolved ions in water. The physical and chemical interactions determine the outcome of the flotation process.

  • COAL FLOTATION Mineral Processing & Metallurgy
    Coal Flotation with non-ionic SurfactantsExperimental Materials and MethodsResults and DiscussionSummary and ConclusionsIn coal flotation, the most commonly used collectors are oily materials collectors such as diesel oil and kerosene. For higher rank coals, the reagent consumption in flotation is low because of the high natural hydrophobicity of the coal. However, for low-rank coals (containing a greater amount of oxygen), flotation performance with these oily collectors is poor and large amount of collectors are required in order to obtain acceptable coal recovery.Polyethoxylated nonyl phenols constitut

  • Physical and chemical interactions in coal flotation

    Sep 29, 2003· 1. Introduction. Conventional froth flotation for fine coal cleaning suffers mainly from two problems: (i) a lack of selectivity for fast floating high rank coals due to the flotation of middlings and entrainment of mineral fines in the froth, and (ii) low recoveries for heavily oxidized or low rank coals due to poor adhesion between bubbles and particles.
