Study on interaction energy between flotation reagent and mineral surface

Abstract

The interaction between a flotation reagent and mineral surface not only depends on the bonding atom, but also depends on the adjacent atom of mineral surface, a flotation reagent and the medium in the system of flotation. Energy equation of a reagent interacting with mineral surface has been deduced from this model. Results of the studies indicate that the interaction energy between mineral surface and a reagent is about several dozen kJ/mol, and the relationship between adsorbing concentration of xanthate on mineral surface and interaction energy is the exponent form.
