The influence of attrition milling on carbon dioxide sequestration on magnesium–iron silicate / Martin Fabian in Minerals engineering, Vol. 23 N° 8 (Juillet 2010)  

Public ISBD [article]  inMinerals engineering > Vol. 23 N° 8 (Juillet 2010) . - pp. 616–620 Titre : The influence of attrition milling on carbon dioxide sequestration on magnesium–iron silicate Type de document : texte imprimé Auteurs : Martin Fabian, Auteur ; Maya Shopska, Auteur ; Daniela Paneva, Auteur Année de publication : 2011 Article en page(s) : pp. 616–620 Note générale : Génie Minier Langues : Anglais (eng) Mots-clés : Olivine Mechanical activation Mössbauer spectroscopy Carbon dioxide Adsorption Résumé : Present work evaluates the structural changes in olivine (Mg,Fe)2SiO4 (deposit Åheim, Norway) generated by mechanical treatment as well as its adsorption properties for carbon dioxide. The high-energy attrition milling was applied for mechanical activation. Identification of the mechanically-induced changes in the mineral was carried out applying various techniques: scanning electron microscopy, Mössbauer spectroscopy, specific surface measurements, carbon dioxide adsorption and Fourier-transformed infrared spectroscopy. The observed changes in the physico-chemical properties illustrate the possibility of the applied activation to modify the surface and/or bulk properties of olivine. Sensitivity for atmospheric CO2 sequestration as well as sequestration of CO2 by chemisorption can be derived from the obtained results.
