Grinding carried out at ordinary temperature on diverse micas (muscovite, lepidolite, phlogopite) involves considerable temperature lowerings of ions OH⁻ and F⁻ liberation. The fluor dissolution cinetic into the water at 80 °C appears also very favoured by previous grinding.Des broyages effectués, à la température ordinaire, sur divers micas (muscovite, lépidolite, phlogopite) entraînent des abaissements considérables des températures de libération des ions OH⁻ et F⁻ . La cinétique de mise en solution du fluor dans l'eau à 80 °C apparaît aussi très nettement favorisée par l'activation mécanique préalable.Grèzes-Besset Raoul, Mouysset-Espagne Marguerite.
