Froth flotation method of separation

Over the last few years, new methods for plastic separation in mining have been developed. Froth flotation is one of these techniques, which is based on hydrophobicity differences between particles. Unlike minerals, most of the plastics are naturally hydrophobic, thus requiring the addition of chemi

  • FLOTATION

    FLOTATION

    Flotation is a generic term for a number of processes known as adsorptive bubble techniques , Lemlich (1972); these are classified into foaming and nonfoaming separation methods. 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

    Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution
