Barite is a mineral composed of barium sulphate (BaSO4). It receives its name from the Greek word “baryte” which means “heavy.” This name is in response to barite’s high specific gravity of 4.5, which is exceptional for a non-metallic mineral. Baryte is generally white or colorless, and is the main source of barium. The baryte group consists of baryte, Celestine, anglesite, and anhydrite. The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and manufacturing uses. Barite also serves as the principal ore of barium.
The term Barytes is derived from the Greek baros meaning heavy. Barite is found in the southern parts of India Barytes (or barite) is a naturally occurring mineral form of barium sulphate. It is extracted by both surface and underground mining. Its main properties are its high specific gravity 4.2 4.5, very low solubility; it is non-toxic, and also chemically and physically non-reactive, low abrasiveness and opaqueness to x-rays.
it is available in lumps and powder form.
In rubber industry, the products less than 600 mesh is used as the filling of rubber products to save cost. It improves the intensity, acid, alkali and water proof. The grinded barite powder is important additive to improve its hardness, wear resistance and anti-aging properties. It makes better the reinforcing action of caoutchouc and synthetic rubber too.
In plastic industry, it is used as the filling of plastic ABS (Acrylonitrile – Butadiene – Styrene) to make the products with bright color. It boosts the intensity, stiffness and abrasive resistance of the plastic.
In medicine, it can be used as barium meal material for the intestines and stomach reflection, and also the filling for plaster.
