Rudolph, Martin published the artcileSpecific surface free energy component distributions and flotabilities of mineral microparticles in flotation-An inverse gas chromatography study, Category: catalysis-chemistry, the publication is Colloids and Surfaces, A: Physicochemical and Engineering Aspects (2017), 380-388, database is CAplus.

In fundamental flotation studies often the contact angle with water is used to describe wettability of a mineral surface and it is correlated with flotability. A more fundamental parameter however is the sp. surface free energy related to the contact angle via Young’s equation. Inverse gas chromatog. (iGC) has recently been proven to be a suitable method to determine sp. surface free energy components and their distributions of particulate surfaces. In this study the pure minerals quartz (SiO2), fluoro-apatite (Ca5[F,(PO4)3]), and magnetite (Fe3O4) are examined for flotabilities and surface energy component distributions considering different methods of sample treatment and the effect of the collectors sodium oleate and dodecyl ammonium acetate. The parameter of specific net free energy of interaction between bubbles and particles immersed in water ¦¤Gpwb resulting from the complex surface energy analyses is introduced and used to evaluate the hydrophobicity of the mineral surface in correlation to microflotation recoveries. The results lead to the hypothesis that only small fractions of the surface and their change of wettability by flotation reagent adsorption will inherently define the flotability of minerals. Consequently, the main purpose of the amphiphilic collector mols. seems to be the reduction of high sp. surface free energies of small fractions of the surface that lead to a strong attraction between particle surface sites and water mols. rather than the hydrophobization of the entire mineral surface, a new paradigm in flotation science.
