Barite (Micronized) 100 gr

BARITE

Barite mineral, which has a natural barium sulfate composition  Since ancient times it has attracted the attention of humanity due to its high specific gravity. It was drawn and called heavy spat, The name Barlt is derived from the Greek word "Barus" , meaning heavy. In nature, it is found as fibrous masses, sometimes lamellar fibrous, rarely as concretions. Thin There are also grainy or earthy looking ones. Matte, sometimes translucent Barite has a glassy or resinous luster .
Barite is usually white in color, but it can be yellow, brown, pink, light green, light blue, gray. and black colored ones is encountered. Barite crystal crystallized in the orthorhombic system has a tabular shape and is cleaved in three directions. They mostly show polysynthetic duplications . The hardness of barite is 2.5-3.5, its specific weight varies between 4.3-4.6, its melting point 1580" is. Chemical composition BaSO4
It is in the form of and contains 65.70% BaO, 34.30% SO3 . The barium content is 58.8%. Apart from the barite mineral, which is most commonly found in nature, barium is replaced by strontium and calcium. The genera into which it was introduced are barita - selestît and barito. - it is called calcite. Apart from these, Viderite (BaCOa) genus is quite common, Salslyan (BaO.Âİ2O3.2SİO2 ) It is rarer. They contain. Sometimes barite containing hydrogen carbide  emits an odor when hit with a hammer. Barite is in water. It almost never melts. Cold Barite, which is insoluble in acid, can dissolve slightly in boiling sulfuric acid

Barite (BaSO4) is a mineral composed of barium sulfate. It is usually white or colorless, but can sometimes be yellow and grey. barium parent is the source. Its glowing form is sometimes called the Bologna Stone.
Barite is usually lead - zinc in limestones. It occurs in veins, hot spring deposits and together with hematite ore. It is often found together with anglesite and celestite minerals. Mohs hardness 3. Refractive index 1.63. Specific gravity 4.3-5. Its crystal structure is orthorhombic.


USAGE AREAS OF BARITETE
The first use of barite was due to its specific gravity and white feature. It was used in the paint, paper and pine industries due to its use, and after 1926, barite barlte since it started to be used in oil and natural gas exploration. The demand has increased rapidly . Barite is mainly used to thicken mud in oil drilling . This mud removing the remains of the drilling, lubricating the drills and rods, lubricating the borehole walls. healthy- solidification and Oil It helps to balance the development of pressurized gas when the expected levels are approached . Drilling mud also as it gets deeper the increasing It creates a balance against its weight. The specific gravity of barite is 4.5, soft being corrosive It is the ideal material used for this purpose because it does not dissolve in water, does not dissolve in water and has a very low price. It ensures that. Around the world 80% of the barite used is consumed in the oil industry. Oil The amount of barite used in drilling depends on the permeability of the formations passed and the gas pressure encountered. is associated with. For example, 3000 mt in oil basins in the south of the USA. For a drilling at a depth of 40 tons of barite, in the North Sea 1000-2000 meters
200-350 tons for a natural gas drilling, oil with high gas pressure in Iran  regions 350 m. depth 100 tons of barite is consumed for the production of barite. Barite is used as an additive in paper, canvas, floor linoleum, rubber and ebonite industries. is used. Increasing brightness in the glass industry, in the production of lenses and TV tubes, and matting the plastic in the plastic industry. To be able to give. agriculture drugs Barite is used as an inert material in its production. .

One of the important areas of use of barite is the paint industry. oil painting It is used as a whitening pigment and thinner in production, but it is used as a constant in the production of quality paint. white and especially lithopone is preferred, Lltopon is a white pigment. Barite is first reduced with coal to obtain BsS. This Reduced Barite sulphide, called black ash, By reacting with zinc sulfate, Litopone is obtained, which is a mixture of synthetic BaSO4 and ZnS. Lithopone mostly paint It is used in the industry and to some extent in the textile, linoleum and paper industry. Known as hard white and chemically pure, Synthetic BaSO4 is obtained by the reaction of BaS with NaSO4 . . Fixed white bya is used in paper photographic paper and medical radiography. Barium sulfate is the basic raw material used in the production of many barium salts consumed in the chemical industry. barium carbonate, barium chloride, barium hydroxide It is used in the production of compounds such as, in the liquidation of sugar, in the electronics, plastics, pesticides industries. Barium dioxide reacts with chlorphoidric acid. It has been used for a long time to produce oxygenated water. Barite, It is used in the production of fireworks because its flame gives a green color .

In recent years, heavy concrete made with the addition of barite has been used in nuclear power plants and gamma from its properties of absorbing rays  It started to be consumed in large quantities due to barite trade, usage It is made in accordance with the specifications required in the fields . Collecting the usage areas into 3 main groups It is possible :

Making Reduced Barite
In the preparation of Utopon, hence the dye and chemistry BaSO4 tenor of barite ore used in industries is 94 • 95%, SiO2 The content must be less than 2% and trace amounts of fluorite . By the presence of silica formation of barium silicate, The efficiency of barium sulphide negative It affects. Fluorite, on the other hand, damages ovens. iron oxide and Strontium sulfate should also be present at less than 1%. Iron oxide in the production of hard white contains trace amounts  must be.

Barite in Drilling
The specific gravity of the barite to be used for this purpose must be at least 4.2, BaSO4 tenor of 94-95% and salt content less than 0-1% is required.
The amount of iron oxide may be 2-3%, but it may be higher due to the corrosive effect of silica  It is inconvenient to have it. It is required that 90-95% of the ground barite be fine enough to pass through a 325 mesh sieve.

Barite to be used in the glass industry contains 96-98% BaSO4 , less than 02% Fe2O3 and trace amounts It must contain TIO2 . Barite used in the tire industry consists of copper and It is undesirable to contain manganese compounds as it impairs the durability of the tire.

In Nuclear Power Plants  Barite
For the production of special heavy concrete used in nuclear power plants The specific gravity of the added barite is 4.2 and it does not contain sulfur minerals
must. Sulphides can cause cracking in cement over time. In heavy concrete construction In order to completely remove the clay from the barite to be used, it must be washed thoroughly. It is sufficient to break the barite to the size of sand and gravel. Apart from all this, barite is fraudulent It also becomes a tool for work. Ground white products such as flour, wax, glue Barite is mixed with materials to make them heavier.

According to its usage areas in industry, barite ore is mostly obtained from quarries. After it is extracted, it is subjected to some refining processes to increase its tenor and quality. Baritene specific èurrun weighs 4.4  fluorite and sulfur minerals using gravimetric methods (JIG, shaking table). Barite ores containing barite can also be purified by flotation. Residue ores produced from deposits
It is subjected to washing to clean it from clay.

Some barite used in the paint industry contain iron, They are washed with sulfuric acid to remove manganese and copper oxides. Barite piece, granule and Sold as ground



Areas of use

The use of barite is generally divided into three: Drilling material (90%), chemical (7%) and filling material (3%).

In its rough form, or simply by washing, sifting, sifting, Barite is the first product to undergo simple processes such as flotation and magnetic separation. finds buyers. The majority of barite in its rough form has a minimum purity and It is processed until it reaches density. Used as heavy cement After barite is crushed, it is sieved and brought to the same size. Most of barite It is ground and used as an additive in industrial products or as an additive in oil or natural gas. It is used as a weight-bearing additive when drilling wells. World Barite used in drilling is according to API 13A international standard, It is produced in Turkey according to TS 919 standard.
