Electrochemistry of sulfides. Theory and practice of flotation

📒 The development and results of electrochemical studies in the field of sulfide flotation are discussed and generalized. The role of oxygen and redox transitions on the sulfide surface in the kinetics of sorption of thiol collectors and the formation of hydrophobic layer on the surface of sulfide minerals is shown. The regularities of autooxidation of thiols catalyzed by cobalt phthalocyanines are described. The effect of inhomogeneity of mineral surface on the wettability of minerals is considered. Theoretical aspects and practical potentialities for enhancing the contrast of physicochemical and flotation properties of sulfides and the reagentless methods for optimization of flotation of polymetallic and gold-bearing sulfide ores are considered. The monograph is intended for the researchers and engineers engaged in the flotation and hydrometallurgy.
