Abstract

A new surface-thermodynamic conception of apolar and polar interfaeial interactions, operating between hydrophilic and/or hydrophobic mineral surfaces, was proposed for the van der Waals and polar (structural) surface force components. Using this model, the interaction energy functions calculated for two interacting paramagnetic model spheres showed that the polar forces play a dominant role in magnetic flocculation.
