Barite has a wide range of δ 34 S values, between 9.3 and 31.5‰ (Table 2; App. Table A2; Fig. 8). Significant variation in δ 34 S values was observed between the different mineralization styles. Barite from the carbonate-hosted mineralization at Lavrion has δ 34 S values from 9.3 to 19.8‰.
API barite was easy to settle down, and under a certain pressure difference, mud cake could be quickly formed which decreased the filtration volume (Fig. 8). API barite/WBDFs showed a bimodal distribution (Fig. 10 and Table 4) which contributed to the less filtration loss. The particle size distribution of mMB/WBDFs showed a unimodal peak.

The saturation indices of barite (SI barite) in the initial solution were fixed at 4.2 by adjusting the Ba 2 + concentration to keep the same initial precipitation rate of barite for experiments. SI is defined as SI = log(IAP/ K sp ), where IAP and K sp are the ion activity product and solubility product of the mineral, respectively.
