The
term barytes is derived from the Greek “baros”
meaning heavy. Ashapura is in this field since last
10 years. Ashapura is exporting Barites to UK, Texas,
Gulf etc. Barite is found in the southern parts of India.
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.
Barytes
is supplied in crude/lump form. Barytes, after suitable
grinding and pulverizing, has many uses. It is mainly
used in oil-well drilling and it is estimated that 90%
of the barytes produced in the world is used only for
drilling purposes. It is also found useful in the manufacture
of white pigment or extender in pigments and barium
chemicals, in the glass industry and as filler in rubber,
leather, textile and paper goods.
Drilling
fluids consume some 85% of the world's total barytes
consumption, making them easily the largest market.
The main functions are :
|
Increase
drilling fluid density with minimum solids |
|
Control
formation pressure |
|
Stabilise
the borehole |

Barytes is used as a weighting agent for drilling fluids
in oil and gas exploration.This meets the American Petroleum
institute (API) specification 13A section 2 requirement.
In
dope and painting, it can be used as filling and can
take the place of some expensive material such as basofor,
crypton, titanium dioxide, activity, monox etc. Control
the viscosity of the paint compatibly to make the products
with bright color, goodstability.
In
plastic industry, it is used as the filling of plastic
ABS to make the products with bright color. It also
can improve the intensity, stiffness and abrasive resistance.
In
rubber industry, the products less than 500 mesh can
be used as the filling of rubber products to save cost.
It can improve the intensity, and acid, alkali, and
water proof, and also has benefit for the Natural Rubber
and Synthetic Rubber.
In
medicine, it can be used as barium meal material for
the intestines and stomach reflection, and also the
filling for plaster and dope to extend the time limit.
In
the papermaking industry, high-refined barites powder
can be used as the filling of white paperboard and coat
paper, improve the whiteness and percentage of coverage.
In
cosmetics, it can be a substitute of titanium dioxide,
for its whiteness, gentleness and harmless ness to skin.
