Carbon dioxide storage in olivine basalts: Effect of ball ...
2015-3-1 · The ball milling process was carried out in a Fritsch Pulverisette 6 planetary mono mill. The olivine basalt was subjected to wet milling in an 80 mL tungsten carbide bowl using deionized H 2 O or ethanol as process control agent (PCA). The ball-to-powder mass ratio was 20:1 w/w, the fluid-to-powder mass ratio 1:10 or 1:2 and the rotation speed 300 rpm.
