Analysis of the settled barite samples revealed that most particles are larger than those in API barite. The size of barite particles rarely exceeds 75 µm (Ofei et al. 2023), so this observed trend toward larger particle sizes in the settled barite samples is noteworthy. This shift could be attributed to the sedimentation and settling ...
