Figure 6
The mean March–Dollase ratio for the albite phase obtained from Rietveld refinements using XRD data of five pyrite concentrate powders milled for different times. A March–Dollase ratio of 1 indicates random powder orientation with respect to the chosen unique reflection direction [013]. Reflection intensities in very low milling time samples with poor particle statistics may also be partially modelled by this parameter. Error bars represent sample standard deviations of the mean values for the five repeats at each milling time. Values are given in Table S3. |
