What is
Barite?
• Chemistry: BaSO4, Barium Sulfate
• Class: Sulfates
• Group: Barite
• Uses: ore of barium, in heavy muds in
oil-well drilling, to increase
brilliance in glass-making industry, as
filler for paper, cosmetics, textiles,
linoleum, rubber goods, paints.
• Specimens
Barite, barites, or heavy spar, a white,
yellow, blue, red, or colorless mineral.
It is a sulfate of barium, BaSO4, found
in nature as tabular crystals or in
granular or massive form and has a high
specific gravity. The mineral is widely
distributed throughout the world. It
often occurs in veins with lead and zinc
minerals. It is insoluble in water, and
this property is made use of in testing
for the sulfate radical. It is
practically insoluble under ordinary
conditions in all the usual chemical
reagents. Barite is used as a commercial
source of barium and many of its
compounds. Ground barite is used as
filler in the manufacture of linoleum,
oilcloth, paper and textile
manufacturing, rubber, and plastics.
Finely ground barite is used to make a thixotropic mud for sealing oil wells
during drilling. Prime white, a bleached
barite, is used as a pigment in white
paint but is not as satisfactory as
blanc fixe, a chemically precipitated
barium sulfate, or lithopone, a mixture
of barium sulfate, zinc sulfide, and
zinc oxide. Barites is a material with
environmental protecting function, it
has a lot of advantages, such as a
strong inertia, good stability, acid and
alkali proof, moderate rigidity, high
specific gravity, high whiteness, absorb
in harmful radial. So, it is widely used
in the fields of all kinds of dope,
middle and high-grade paint, engineering
plastic, medicine compounding chemical
industry, rubber, paper-making, pottery,
cosmetic etc. Barite is a common mineral
and makes very attractive specimens. It
often is an accessory mineral to other
minerals and can make a nice backdrop to
brightly colored crystals. At times
bladed or tabular crystals of Barite
form a concentric pattern of
increasingly larger crystals outward.
This has the appearance of a flower and
when colored red by iron stains, these
formations are called "Desert Roses".
Because Barite is so common, it can be
confused for other minerals. Celestite
(SrSO4) has the same structure as barite
and forms very similar crystals. The two
are indistinguishable by ordinary
methods, but a flame test can
distinguish them. By scrapping the dust
of the crystals into a gas flame the
color of the flame will confirm the
identity of the crystal. If the flame is
a pale green it is barite, but if the
flame is red it is celestite. The flame
test works because the elements barium (Ba)
and strontium (Sr) react in the flame
and produce those colors.
Barite
General Information
Barite, a name that was derived from the
Greek word "barus" (heavy), is the
mineralogical name for barium sulfate.
In commerce, the mineral is sometimes
referred to as "barytes." The term
"primary barite" refers to the first
marketable product, which includes crude
barite (run of mine) and the products of
simple beneficiation methods, such as
washing, jigging, heavy media
separation, tabling, flotation, and
magnetic separation. Most crude barite
requires some upgrading to minimum
purity or density. Barite that is used
as an aggregate in a "heavy" cement is
crushed and screened to a uniform size.
Most barite is ground to a small,
uniform size before it is used as a
filler or extender, an addition to
industrial products, or a weighting
agent in petroleum well drilling mud
specification barite. Although barite
contains a "heavy" metal (barium), it is
not a toxic chemical under Section 313
of the Emergency Planning and Community
Right-to-Know Act of 1986, because it is
.
Barite generally occurs in the white
massive variety (often appearing earthy
when weathered), although some clear to
bluish, bladed barite crystals (Plate
18) have been observed in several vein
deposits, and various nodular zones have
been observed. Rosettes are common in
many Iranian mineral veins. Feathery
barite is also known from Iran.
Barite is extremely insoluble in acid
and water and is therefore chemically
inert. It is the principal source of the
element barium. Barite is the most
abundant of the semi-commercial
vein-forming minerals in Iran. Until
World War I, barite was mined along with
fluorite and sphalerite. Limited barite
mining was attempt during the 1960's in
other counties Commercial barite was
recovered as a by-product of the
fluorspar industry Iran during World War
II and during the 1960's.
Barite Geology [BaSO4]
A dense sulfate mineral that can
occur in a variety of rocks, including
limestone and sandstone, and is commonly
used to add weight to drilling mud.
Barite is of significance to
petrophysicists because excess barite
can require a correction factor in some
well log measurements.

Barite Uses
Drilling
Weighting material with a specific
gravity of 4.37 used to increase the
apparent density of a liquid drilling
fluid system. Barite [BaSO4] is the most
common weighting agent used today. It is
a mined material ground to an API
specification such that particle sizes
are predominantly in the 3 to 74 micron
range.
Drilling Fluids
A dense mineral comprising barium
sulfate [BaSO4] that commonly occurs
with a range of accessory minerals, such
as quartz, chert, dolomite, calcite,
siderite and metal sulfides. Used as a
weighting agent for all types of
drilling fluids, barites are mined in
many areas worldwide and shipped as ore
to grinding plants in strategic
locations. Pure barium sulfate has a
specific gravity of 4.50 g/cm3, but
drilling-grade barite is expected to
have a specific gravity of at least 4.20
g/cm3 to meet API specifications.
Contaminants in barite, such as cement,
siderite, pyrrhotite, gypsum and
anhydrite, can cause problems in certain
mud systems and should be evaluated in
any quality assurance program for
drilling-mud additives.
Barite Industrial Applications
Barites is supplied in crude/lump
form. Barites, after suitable grinding
and pulverizing, has many uses. It is
mainly used in oil-well drilling and it
is estimated that 90% of the barites
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.
Painting
Industry
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, good stability.
Plastic
Industry
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.
Rubber
Industry
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.
Pharmaceutical Industry
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.
Paper-Making Industry
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.
Cosmetics Industry
In cosmetics, it can be a substitute
of titanium dioxide, for its white and
gentle, and harmless to the skin.

Barite Specifications
Drilling fluids consume some 85% of the
world's total barytes consumption,
making them easily the largest market.
The price of drilling grade barytes
depends primarily on demand from the oil
and gas exploration industry and on the
price of oil. After 2003 an oil glut
could force oil prices down and reduce
barytes demand, but experience shows
that many other factors, such as the
severity of the northern hemisphere
winter and political conflict in the
producing countries, could change this
picture. Environmental concerns in
offshore drilling will also impact on
future barytes prices, as quality
demands become more stringent. Barytes
that is co-produced during base metal
mining and flotation may become
increasingly difficult to market, and
alternatively, metal-free material will
be in greater demand. This should push
barytes prices up. The USA is easily the
largest barytes consumer, accounting for
40% of world demand in 2001, most of
which is imported. China is the other
major barytes consumer, accounting for
14% of world demand, although in this
case demand is met from domestic
production. Oil and natural gas are
expected to increase their share of
total energy requirements from 62% in
2000 to 67% in 2020, which will increase
demand for drilling grade barytes in
exploration and development.
