BEHAVIOUR OF α-NITROSO-β-NAPHTHOL IN HEMATITE FLOTATION

Based on theoretical calculation of electronegativity of groups of flotation reagent andmethod of infrared adsorption spectroscopy,the collection and adsorption of α-nitroso-β-naphthol in hematite flotation have been studied.The chemical adsorption seems to bepredominant owing to formation of pentacyclic nitrosyl chelate compound by atoms ofnitrosyl bond in α-nitroso-β-naphthol together with Fe(Ⅲ)on hematite surface.Mean-while,the nonuniform multilayer physical adsorption is also occurred.
