  • Flotation Surfactant Applied And Interdisciplinary Physics

    Flotation Surfactant Applied And Interdisciplinary Physics

    Flotation is the process of seperation of mixed liberated particles from each other if there are sufficent differences in their wettability. The ore is ground into a fine powder and mixed with water to form a slurry. The desired mineral is rendered hydrophobic lacking affinity for water by the addition of a surfactant. The hydrophobic grains of mineral-bearing ore escape the water by ...
