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.
