Arsenic sorption on mechanically activated minerals such as magnetite Fe 3 O 4 (Kiruna, Sweden) and olivine (Mg,Fe) 2 SiO 4 (.heim, Norway) has been studied and compared in this work. Experiments were carried out with non-activated and mechanically activated samples. The activation of both minerals was performed in a planetary mill at different milling conditions. The specific surface area and consequent sorption activity were enhanced by mechanical activation. The using of olivine seems to be better than magnetite from the point of view of milling time, which is necessary for achievement of the same sorption effect.
