1. Drilling mud weighting agent  In some oil and gas well drilling, 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 generally has a fineness of more than 325 mesh. If the fineness of the barite is insufficient, precipitation is likely to occur. The barite for drilling mud requires a specific gravity greater than 4.2, the BaSO 4 content is not less than 95%, and the soluble salt is less than 1%.  Convex Shaped Magnet,Ndfeb Shaped Magnet,Tile Arc Shaped Magnet,A Horseshoe Magnet Dongguan Zhenglong Magnet Co., Ltd , https://www.zlctmagnetism.com
2, zinc bismuth white pigment 钡 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 (ZnSO 4 ) to obtain a mixture of barium sulfate and zinc sulfide (BaSO 4 accounts for 70%, ZnS accounts for 30%) Zinc bismuth white pigment. The preparation of zinc-white barite requires a BaSO 4 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 industrial use In the paint industry, barite powder filler can increase the thickness, strength and durability of the film. 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 improves the hardness, wear resistance and aging resistance of rubber and plastics. 
Barite fillers for rubber and papermaking generally require BaSO 4 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 掺 The use of barite and fluorite composite mineralizer in cement production has obvious effects on promoting C 3 S formation and activation of C 3 S, 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 using 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. In coal gangue material as the cement raw meal by adding an appropriate amount of barite, can cement clinker is lower than the saturation intensity, especially early strength has been greatly improved, which for the utilization of gangue, for the production of Low calcium, energy saving, early strength and high strength cement provide a beneficial way. 
6, anti-ray cement, mortar and concrete using  barite having an X-ray absorbing properties of cement made with barite prepared barium, barite barite mortar and concrete to shield a nuclear reactor instead of the metal grid and Construction of scientific research, hospital anti-X-ray buildings. 
Tantalum cement is made of barite and clay as the main raw material. After sintering, the clinker composed of dimuth silicate as the main mineral is added, and the appropriate amount of gypsum is added 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 1:0î€25:2î€5:1.  barite concrete is a greater volume weight, having an X-ray shielding ability of concrete, cementitious materials are generally low heat of hydration of Portland cement or a high aluminum cement, cement, barium, strontium, special cement and cement. Portland cement is the most widely used. The commonly used cement: barite crushed stone: barite sand: water mixture ratio is 1:4î€54:3î€4:0î€5; 1:5î€44:4î€46:0î€ 6; 1: 5:3î€8:0î€2 three. 
Anti-rays do barite mortar and concrete, BaSO 4 content must not be less than 80%, the gypsum contained therein, pyrite, sulfides and sulfates and other impurities should not exceed 7%. 
7. Road Construction 橡胶 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.
8. Others  Barite and oil are blended and applied to the cloth base 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.
