Arsenic Sorption on Mechanically Activated Magnetite and Olivine

Zdenka Bujňáková / Erika Turianicová / Peter Baláž

Arsenic sorption on mechanically activated minerals such as magnetite Fe3O4 (Kiruna, Sweden) and olivine (Mg,Fe)2SiO4 (Ǻheim,Norway) has been studied and compared in this work. Experiments were carried out with non-activated and mechanically activatedsamples. The activation of both minerals was performed in a planetary mill at different milling conditions. The specific surface areaand consequent sorption activity were enhanced by mechanical activation. The using of olivine seems to be better than magnetite fromthe point of view of milling time, which is necessary for achievement of the same sorption effect.
