  • FLOTATION Thermopedia

    Foaming methods require the addition of surfactants to generate a relatively stable foam or froth which then acts as a carrier fluid during particle removal. The properties most important in determining the success of a flotation process are solid hydrophobicity, bubble to particle size ratio, and the extent of turbulence in the fluid.
