Abstract Based on theoretical calculation of electronegativity of groups offlotation-reagent and method of infra-red adsorption spectroscopy, the collection andadsorption of α-nitroso-β-naphthol in hematite flotation have been studied. The chemicaladsorption seems to be predominant owing to formation of pentacyclic nitrosyl chelate com-pound by atoms of nitrosyl bond in α-nitroso-β-naphthol together with Fe~(3+) on hematitesurface. Meanwhile, the non-uniform multi-layer physical adsorption is also occurred.
