Production of Barium Sulfide from Low-Grade Barite Ores

The manufacture of barium sulfide or barium salts (BaS, BaCl2, Ba (OH)(2), among others) requires high-purity barite ores (>90%). In this study, a new method to produce barium sulfide from low-grade barite ores (60% purity) is proposed. The method involves gravitational concentration of barite ore on a shaking table followed by mechanical activation of the…
