Abstract In the weighting drilling fluid, barite will adsorb the free water and additives in the drilling fluid, which often worsens the performance of the drilling fluid. In order to optimize the performance of drilling fluid, a method for measuring the specific surface area of powder in liquid phase based on low field nuclear magnetic resonance …

The pelagic barite precipitation in the seawater column is tightly associated with the biological pump, and thus the barite Ba isotope composition (δ 138/134 Ba) has been advocated as a novel paleo-productivity proxy. However, pelagic barites in sediments are susceptible to diagenetic processes that may modify primary δ 138/134 Ba signals …

Using 1-octadecyl ester-1, 2-benzenedicarboxylic acid (OEBA) as a collector, the flotation separation of fluorite, calcite and barite was investigated in this paper. The micro-flotation results showed that OEBA efficiently floated out fluorite and barite from calcite at pH ∼ 9.0, and barite from fluorite at pH ∼ 11.0.
