TOPAS results for a fluorite sample ground in a jar of new design (3-lifter jar, 32 h at Ω = 200 r min−1, main disc/jar coupling ; Broseghini, 2017). (a) The powder pattern was modelled by assuming two separate fluorite fractions, respectively, nanocrystalline and sub-microcrystalline, with MgO and ferritic steel as contaminants. (b) The size distribution of the two fluorite fractions: fine fraction (blue) and coarse fraction (green). |
