  • The flotation mechanisms of molybdenite fines by neutral oils were investigated through microflotation test,turbidity measurements,infrared spectroscopy,and interfacial interaction calculations.The results of the flotation test show that at pH 2-11,the floatability of molybdenite fines in the presence of transformer oil is markedly better than that in the presence of kerosene and diesel oil.The addition of transformer oil,which enhances the floatability of molybdenite fines,promotes the aggregation of molybdenite particles.Fourier transform infrared measurements illustrate that physical interaction dominates the adsorption mechanism of neutral oil on molybdenite.Interfacial interaction calculations indicate that hydrophobic attraction is the crucial force that acts among the oil collector,water,and molybdenite.Strong hydrophobic attraction between the oily collector and water provides the strong dispersion capability of the collector in water.Furthermore, the dispersion capability of the collector,not the interaction strength between the oily collectors and molybdenite,has a highly significant role in the flotation system of molybdenite fines.Our findings provide insights into the mechanism of molybdenite flotation.

      Abstract
    • The flotation mechanisms of molybdenite fines by neutral oils were investigated through microflotation test,turbidity measurements,infrared spectroscopy,and interfacial interaction calculations.The results of the flotation test show that at pH 2-11,the floatability of molybdenite fines in the presence of transformer oil is markedly better than that in the presence of kerosene and diesel oil.The addition of transformer oil,which enhances the floatability of molybdenite fines,promotes the aggregation of molybdenite particles.Fourier transform infrared measurements illustrate that physical interaction dominates the adsorption mechanism of neutral oil on molybdenite.Interfacial interaction calculations indicate that hydrophobic attraction is the crucial force that acts among the oil collector,water,and molybdenite.Strong hydrophobic attraction between the oily collector and water provides the strong dispersion capability of the collector in water.Furthermore, the dispersion capability of the collector,not the interaction strength between the oily collectors and molybdenite,has a highly significant role in the flotation system of molybdenite fines.Our findings provide insights into the mechanism of molybdenite flotation.
