Apolar Physically-Adsorbed Agents In Froth Flotation

Mechanism of the action of nonpolar physically adsorbed reactants in froth flotation is under discussion in the paper. It is shown that their basic influence on flotation includes removing of the kinetics restrictions of the flotation complex formation. Experimental data and practical evidence reported in the paper sustain the proposed mechanism. There are discussed potential dependence of the kinetics of dixanthogen formation on platinum and its influence on the induction time (IT).
