What is Barite?

Barite, or Bayite, (BaSO4) is a mineral consisting of barium sulfate. Barite itself is generally white or colorless, and is the main industrial source of barium. Barites, when pure, contain 58.8% barium and 41.2% sulphate. Barites can sometimes contain Strontium (Sr), and forms a complete solid solution series to the mineral Celestine (SrSO4).

Specific gravity (SG) of 4.5 g/cm3 is Lead to count Barite as a heavy mineral. High density, chemical inertness and abundance make Barite a precious mineral for drilling fluids. Increasing weight of drilling mud is the most important application of Barite.

Barite Occurrence

Barite often fills vacant spaces between crystals in sediments and sedimentary rocks. It is especially common in heavily weathered limestone and dolostone. Many of the economic Barite ores are produced from these residual deposits.

Barite is also found as concretions in sand and sandstone. Barite fills sandstone with crystallization within the interstitial spaces between sand grains. Sometimes crystals of Barite in sandstone have very interesting shapes. These structures are called “Barite roses”.

Barite is also a common mineral in hydrothermal veins. It is found in association with ores of antimony, cobalt, Copper, Lead, manganese and silver. In a few cases Barite is deposited at hot springs.

Economic Classification

The industrial specifications for different use of barites vary widely, even among manufacturers or industries. In order to assess the quality of barite ores from the studied fields, the measured geotechnical and geochemical properties are compared with some generally acceptable standards for processed barite. American Society for Testing and Materials (ASTM) and American Petroleum Institute (API) are two organizations provide a general specification standard for Barite Ores.

Barite Usages:

Most of produced Barite is used as a weighting agent in drilling muds. These dense muds are pumped down the drill rod, exit through the cutting bit and return to the surface between the drill rod and the wall of the well. This flow of fluid does two things:

  1. Cooling the drill bit;
  2. Suspending the rock cuttings produced by the drill and carrying them up to the surface.

Barite is also used as a pigment in paints and as weighted filler for paper, cloth and rubber. The paper used to make some playing cards has Barite packed between the paper fibers. This gives the paper suitable density that players need to play easily.

Barite is the major source of barium, which is used to make a wide variety of barium compounds. Some of these are used for x-ray shielding. Barite has the ability to block x-ray and gamma-ray emissions. Barite is used to make high-density concrete to block x-ray emissions in hospitals, powerhouses, and laboratories.

Barite compounds are also used in diagnostic medical tests. If a patient drinks a small cup of liquid that contains a barium powder in a milkshake consistency, the liquid will coat the patient’s esophagus. An x-ray of the throat taken immediately after the “barium swallow” will image the soft tissue of the esophagus (which is usually transparent to x-rays) because the barium is opaque to x-rays and blocks their passage. A “barium enema” can be used in a similar way to image the shape of the colon.
