After only 5 min grinding, it is observed a significant decrease in the energy required for the total dehydroxilation of the three minerals, especially as far as chrysotile in concerned, as a consequence of strong structural alteration in the 1:1 silicate layer. In fact, after 5 min of grinding, the original stacking layers rolled to assume the characteristic fibrous habit of chrysotile were delaminated; therefore, the .

Methods: Sepiolite (SepSp1), nontronite (NAu2), Montmorillonite (SAz2 and SWy1) were obtained from the clay minerals society. Samples were analyzed with their native exchangeable cations and one aliquot of SWy1 was exchanged with Fe3+ to increase the total iron content. All samples were ground and dry sieved to <45 µm.
