  • Barite USGS Publications Warehouse

    An estimated 1.3 million tons of barite (from domestic production and imports) was sold by crushers and grinders operating in seven States. Typically, more than 90% of the barite sold in the United States is used as a weighting agent in fluids used in the drilling of oil and natural gas wells.Prevention of hematite settling using synthetic layered,611· Hematite (Fe 2 O 3) is used as a weighting material to increase the density of the drilling fluid. Hematite has a higher density (5.05 g/cm 3) compared with barite (4.2 g/cm 3 ). Because of the high specific gravity and particle size, hematite can separate and settle down at higher temperatures (> 250 °F).
