    COAL FLOTATION - Mineral Processing Metallurgy. Coal Flotation with Non-Ionic Surfactants. In 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.

  • 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 constitute a m...
