    OverviewIndustriesHistoryPrinciple of operationScience of flotationFlotation equipmentMechanics of flotationChemicals of flotation

    Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and

  • Flotation Collectors - Mineral Processing Metallurgy

    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).
