摘要：
By the analysis of oleinic acid flotation of fluorite and hematite, it is inconsistent to use thermodynamic approach to explain the flotation effect by the chemical adsorption of the reagent only. The authors propose a hypothesis that collecting ability of a flotation reagent relates with the activity of its physical adsorption at the air-liquid interface. The hypothesis is supported with the data on flotation of rutile, zircon and fluorite. Capability of surface pressure of film generated by molecules or ion-molecule associates as the criterion of collecting ability of a flotation agent is defined.
