摘要: Abstract This study investigates the effect of dry mechanical activation olivine as a pre-treatment step prior to wet milling with respect production specific surface area. Milling experiments combining two modes (i.e. and wet) were performed using laboratory planetary mill. The area milled products was determined by N 2 -adsorption (BET), whereas their crystallinity studied X-ray diffraction (XRD). Combining subsequent makes it possible produce at rates that exceed those can be obtained alone. Whereas value 26.28 ± 1.28 m /g after 30 min milling, 25 min followed 5 min resulted in 64.44 ± 2.13 m /g. concept could represent significant energy savings, enable combine high an activated structurally disordered surface.
