Barite Powder Selection
If the dosage of the barium salts is small, a removal ratio of sulfuric acid ions is reduced. If the dosage of barium salts is large, barium remains as an impurity disadvantageously. The barium sulfate obtained from the solid liquid separation process has high purity, and may be commercially sold as a separate product after washing and drying.28 zinc sulfide (ZnS) and 72 barium sulfate (BaSO. 4), which is used as a white pigment in paints. Barium sulfate is produced from high grade (75–98 ) ore in association with granite and shale, crushed, and then beneficiated by washing, jigging, heavy media separation, tabling, floatation, or magnetic . separation (Stokinger 1981 USGS 2004).
