Barite (or baryte) is a mineral composed primarily of barium sulfate.
... Properties of Barite (Barytes)
Hardness: 3 on Mohs scale
Density: 4.50 g/cm3 (Measured) 4.50 g/cm3 (Calculated)
... Environmental Concerns
Although the metal barium is toxic, barite itself is non-toxic due to the extreme insolubility of barite.
Many barite deposits also contain heavy metals such as lead. ...
... What is Barite or Baryte (Barytes)?
Barite is also called Baryte or Barytes. It is a mineral which is usually white or colorless (transparent). The name Baryte is derived from the Greek word for “heavy” which is “Barys” (barus).
What is Barite (Baryte) made of?
Barite is a non-metallic mineral made up of Barium Sulphate. The chemical formula of Barite is BaSO4.
Some Interesting Facts About Barite (Barytes)
The Greek origin of the name (Barus)which means “heavy” refers to the rather high specific gravity of Barite (specific gravity = 4.5) in-spite of being a non-metallic mineral.
This unusually high specific gravity of Barite makes it a highly sought-after mineral with specialized uses in different industries as varied as Gas and Oil Drilling to Cosmetics Manufacture. ...
Barite (baryte, barytes; BaSO4) is the most abundant barium mineral in the Earth's crust. It has orthorhombic symmetry, forms good crystals and has good cleavage (perfect along 001). It is relatively insoluble in water. It is isostructural with celestite (SrSO4) and there is a complete solid solution series between BaSO4 and SrSO4, although natural compositions are usually near the end members. PbSO4 (anglesite) is isostructural with BaSO4 (barite), so a complete solid solution between these two end members would also be expected; some natural samples do occur that are intermediate in composition. At room temperature, about 6% Ca2 + can be accommodated in the BaSO4 structure. About 8% Ba2 + replacement of Ca2 + is the limit of solid solution tolerated by the CaSO4 (anhydrite) structure. ...
Barytes (or barite) is the naturally occurring mineral form of barium sulphate. Its main properties are its high specific gravity (4.5), very low solubility; it is non-toxic, and also chemically and physically unreactive.
It is extracted by both surface and underground mining, followed by simple physical processing methods to produce correctly sized product and to remove extraneous materials. ...
Barite (spelled baryte in British publications) was named from the Greek word baros which means weighty, a reference to its unusually high specific gravity. (Specific gravity is a mineralogist’s measure of the density of a mineral; this is done by comparing the weight of the mineral to the weight of an equal volume of water.) ...
Baryte, barite or barytes (UK: /ˈbærʌɪt/, /ˈbɛəraɪt/) is a mineral consisting of barium sulfate (BaSO4). Baryte is generally white or colorless, and is the main source of the element barium. The baryte group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba,Sr)SO4.
Names and history
The radiating form, sometimes referred to as Bologna Stone, attained some notoriety among alchemists for the phosphorescent specimens found in the 17th century near Bologna by Vincenzo Casciarolo.
The American Petroleum Institute specification API 13/ISO 13500, which governs baryte for drilling purposes, does not refer to any specific mineral, but rather a material that meets that specification. In practice, however, this is usually the mineral baryte. ...
