Measurements were made of the effect of temperature on the rate at which Mg, Fe, and Al were dissolved from clinochlore, a Mg-rich orthochlorite mineral, by acid. The Mg, Fe, and Al were dissolved at the same rate with the same activation energy of 21 kcal/mole. The data indicated that the reaction proceeded from the particle edges inwards and was controlled by diffusion.
