Baryte or Barite
*BaSO4*
This mineral only exists in crystalline form due to the presence of sulfer and oxygen as binders.
Characteristics of Baryte:
Barite (baryte) is a mineral composed of barium sulfate (BaSO4). The mineral barite (BaSO4) is the principal ore for the element barium, which has the chemical symbol Ba. The heavy metal barium is silvery, soft, highly reactive, and does not occur in its elementary form in nature. Barium is commonly found within the mineral barite, bound with sulfur and oxygen. Baryte often occurs as white or colorless tabular crystals and occasionally yellow/brownish or blue tone crystals can be found. The exploration for and development of petroleum and natural gas resources accounts for nearly 95 percent of domestic consumption and about 90 percent of global consumption of baryte.
Geological Setting: Commonly found as a gangue mineral in metallic ore deposits of epithermal or mesothermal origin; but it may also be found as lenses or replacement deposits in sedimentary rocks, both of hypogene and supergene origin.
Uses of Baryte:
Barite is considered a "critical mineral" in domestic metallurgical applications that serve energy technologies (Fortier and others, 2018). The mineral barite is a key component in drilling mud, which is used in the oil and gas industry to prevent blow-outs, where high pressures at depth can force material upwards through the drill shaft. Mined barite is ground to a fine powder and mixed with mud to make a heavy slurry. The mud is then poured down the drill hole creating a plug around and above the drill bit. Because barite is soft, it does not damage the drill bit, but due to its high specific gravity, barite effectively counteracts upward pressure, confining the oil or gas and reducing the likelihood of a blow-out.
Elemental barium is an additive in optical glass, ceramic glazes, and other products. Barite is used as a weighing agent in a variety of other applications, including paper, brakes, and even playing cards. It is commonly used in the production of paints, rubber, and as a filler or to improve brilliance and clarity. The medical industry uses barite for radiation shielding, or to increase contrast in radiographs.
