Direct barite determination using SEM/EDS-ACC system: …
The total barite concentration, C total, and the particle size distribution are measured with the SEM/EDS-ACC system and the mean barite mass is calculated from Eq. (1), assuming 100 wt.% barite: (3) M barite =1/C total. The mean mass of barite crystals thus calculated for sample KTB03 is 10.0±0.5 pg (Table 2).
