“Barite” is a mineral and it’s name originates from the Greek word “Barus” meaning heavy. It is a mineral that can be found along with limestones and sandstones. The physical properties of this mineral indicates that it has specific weight (γ) of 4.1 to 4.6 and is heavier than most non-metal minerals.
- Barite is widely used as a weighting agent in drilling mud. It is mostly applied to sustain well stability by maintaining mud weight to prevent blowouts.
- Barite has the ability to prevent emission of X-rays and gamma rays. Therefore it is used to make high-density concrete to prevent X-rays from being emitted in hospitals, power plants, and laboratories. The anti-radiation feature is also used in internal photography of the human body.
- Used as filler in plastic, pulp, and rubber industries.
- Absorbs radioactive radiation due to its high specific weight.
- Production of cement blocks.
- Barium Sulfate is mostly used in the rubber companies, pulp and paper, textile, and leather industries.
- Barium Carbonate is utilized for polishing ceramics.
- Barium Oxide is mostly applicable in the glass manufacturing and metallurgy.
- Due to the exclusive physical properties of Barite, it is mainly used as filler and diluent to increase viscosity. Barite is not the only mineral used in the medical industry and other minerals such as Bentonite, Calcite, Magnesite, etc., have medical applications too.
