Kinetic study of acid attack on sepiolite; textural changes
Etude cinetique de l'attaque acide de la sepiolite; modifications des propietes texturales
Clay Minerals (March 1986) 21 (1): 69-84
The influence of different operational variables used during the acid treatment (HCl) of sepiolite on the rate of extraction of Mg ions and textural properties of the resulting products is described. A model is given from which kinetic parameters and the activation energy of the process are calculated.
