In the oil-based WARP project the barite is milled to a particle size specification where typically 60 of the particles are less than 2 micron. The particle size distribution is measured by a particle size analysis on a Malvern Mastersizer 2000 using optical model Rl1.7 Absorption 0.05 and Rl1.46. The high-density slurries produced are then .
