Barite is a non-metallic mineral product containing barium sulfate (BaSO4 ) as the main component.Pure barite is white and shiny. It is often gray, light red, light yellow, etc. due to the influence of impurities and impurities. Crystallization Quartite, which is quite good, can also appear as a transparent crystal. The barite has a hardness of 3 to 3.5 (Mohs) and a specific gravity of 4.3 to 4.7, and has the characteristics of large specific gravity, low hardness, and brittleness. Barite is chemically stable, insoluble in water and hydrochloric acid, non-magnetic and toxic.
Why Barite Powder Processing Plants Will Change Your Life? Barite powder processed by barite powder processing plant is a very important non-metallic mineral raw material with a wide range of industrial uses?
1. Drilling mud weighting agent?
When drilling some oil and gas wells, the drilling mud and clay generally used have a specific gravity of about 25, and the specific gravity of water is 1. Therefore, the mud weight is low, and sometimes the mud weight cannot be balanced with the underground oil and gas pressure. , causing a blowout accident. In the case of high underground pressure, it is necessary to increase the specific gravity of the mud. Adding barite powder to the mud is an effective measure to increase the specific gravity of the mud. The barite used for drilling mud should have a fineness of more than 325 mesh. If the barite is not fine enough, it will precipitate easily. The barite for drilling mud requires a specific gravity of more than 4.2, the BaSO4 content is not less than 95%, and the soluble salt is less than 1%.
2. Zinc bismuth white pigment?
Zinc bismuth white is a commonly used high-quality white pigment, can be used as a raw material for paints and paints. Heating barium sulfate, using a reducing agent to reduce to barium sulfide (BaS), and then reacting with barium sulfate (ZnSO4 ) to obtain a mixture of barium sulfate and zinc sulfide (BaSO4 accounts for 70%, ZnS accounts for 30%) Zinc bismuth white pigment. The preparation of zinc-white barite requires a BaSO4 content of greater than 95% and should not contain visible colored debris.
3. Various antimony compounds?
Quartz can be used as raw materials to produce chemical raw materials such as antimony oxide, barium carbonate, barium chloride, barium nitrate, precipitated barium sulfate and barium hydroxide.
Chemically pure barium sulfate is the standard for measuring whiteness; barium carbonate is an important raw material for optical glass, which introduces BaO into glass, thereby increasing the refractive index of glass and improving other optical properties; Barium chloride is an agricultural pesticide; barium nitrate is used in the fireworks and glass industries; barium permanganate is a green pigment.
4. Barite for filler industry?
In the paint industry, barite powder filler can increase film thickness, strength and durability. Zinc antimony pigments are also used in the manufacture of white paints, which have more advantages than lead white and magnesium white. Barite used in the paint industry requires sufficient fineness and high whiteness.
The paper industry, rubber and plastics industries also use barite as a filler, which increases the hardness, wear resistance and aging resistance of rubber and plastics.
Barite fillers for rubber and papermaking generally require BaSO4 to be greater than 98% and CaO to be less than 0.36%. Magnesium oxide, lead and other components are not allowed.
5. Mineralizer for cement industry?
The use of barite and fluorite composite mineralizer in cement production has obvious effects on promoting C3S formation and activation of C3S, and the quality of clinker has been improved. The early strength can be increased by about 20 to 25%, the late strength is increased by about 10%, and the clinker firing temperature is lowered from 1450° C to 1300 ± 50° C. When the amount of barite is 0.8 to 1.5%, the effect is the best. In the production of white cement, after the barite and fluorite composite mineralizer, the firing temperature is reduced from 1500°C to 1400°C, the free CaO content is low, and the strength and whiteness are improved. Adding an appropriate amount of barite to the cement raw meal using coal gangue as raw material, the cement strength of the clinker saturation ratio, especially the early strength, can be greatly improved, which is the comprehensive utilization of coal gangue. The production of low calcium, energy saving, early strength and high strength cement provides a beneficial way.
6. Anti-radiation cement, mortar and concrete?
Using barite to absorb X-rays, using barite as bismuth cement, barite mortar and barite concrete, instead of metal lead plate shielding nuclear reactor and construction Research, hospital anti-X-ray buildings.
Tantalum cement is made of barite and clay as the main raw material, and is obtained by sintering to obtain clinker composed of dimuth silicate as the main mineral, and then adding appropriate amount of gypsum to grind together. The specific gravity is higher than that of ordinary Portland cement, which can reach 4.7-5.2. The strength number is 325-425. Due to the large specific gravity of the concrete, it can be combined with heavy aggregates (such as barite) to form a uniform and dense anti-X-ray concrete.
Barite mortar is a kind of mortar with large bulk density and barrier effect on X-rays. It is generally required to use Portland cement with low hydration heat. Commonly used cement: barite powder: barite sand: coarse sand The ratio is 1:0.25:2.5:1. • Barite concrete is a kind of concrete with large bulk density and shielding ability for X-rays. Cementitious materials generally use Portland cement with low hydration heat or special cement such as high alumina cement, strontium cement and strontium cement. Portland cement is the most widely used. Commonly used cement: barite crush: barite sand: water mix ratio is 1: 4.54: 3.4: 0.5/ 1: 5.44: 4.46: 0.6/ 1: 5: 3.8: 0.2 three kinds.
For anti-radiation mortar and concrete barite, the content of BaSO4 should not be less than 80%, and the impurities such as gypsum, pyrite, sulfide and sulfate should not exceed 7%.
Rubber and asphalt mixture containing about 10% barite have been successfully used in parking lots and are a durable paving material. At present, the tires of heavy road construction equipment have been partially filled with barite to increase the weight and facilitate the compaction of the filling area.
Barite and oil are blended and applied to the cloth to make tarpaulin; barite powder is used to refine kerosene; in the pharmaceutical industry, it can be used as a digestive tract contrast agent; it can also be used for pesticides, leather making, fireworks, etc. In addition, barite is also used as an extraction metal crucible for use as a getter and binder for televisions and other vacuum tubes. It is alloyed with other metals (aluminum, magnesium, lead, calcium) for bearing manufacturing.
