GENERAL
DESCRIPTION & APPLICATIONS
|
Barite
is the most common barium mineral. It is a sulfate of
barium found in nature as in tabular crystals, granules,
or compact masses and has a high specific gravity (4.5).
Its colors are variable (white, blue, green, yellow
and red shades) and crystal system is orthorhombic.
Barite occurs widely throughout the world. It often
occurs in hydrothermal ore veins with lead, and zinc
minerals. It is insoluble in water and practically insoluble
in the most chemical reagents under ordinary conditions.
Barite is used the chief source of barium and its chemical
compounds. Ground barite is used as a filler in the
manufacture of linoleum, oilcloth, paper and textile
manufacturing, rubber, and plastics. Ground barite is
used in the oil industry, e.g., as filtering and deodorizing
agents in the refining of petroleum and, mixed with
other materials, as drilling muds to protect the cutting
bit while drilling. Bleached barite (white barite) is
used in making paint as a white pigment. |
