Abstract :
The chemical adsorption of a complexing collector as the sodium oleate onto fluorite is highlighted by high frequency dielectrical measurements (0.4 – 120 MHz). Physical adsorption of collector acting by electrostatic effect as dodecylamine and dodecylsulfate has no influence on the dielectric properties of mineral pulp. The dielectric method allows to analyze the adsorption phenomena during the monolayer formation.
