Barite is a non-metallic mineral composed mainly of barium sulfate (BaSO₄), belonging to the orthorhombic crystal system. It is the most common barium mineral, with excellent characteristics such as high density, chemical stability, and acid-base resistance. Known as the "industrial MSG," it holds an important position in national economic development.
Barite has a Mohs hardness of 3-3.5 and a specific gravity of 4.3-4.7. Pure barite appears white with a glossy finish. Due to different impurities, it can appear gray, light red, light yellow, etc. Barite powder is widely used in oil drilling mud weighting agents, chemical barium salt raw materials, paint fillers, medical contrast agents, building materials, and glass manufacturing.
Statistics show that approximately 1 ton of barite powder is consumed for every 30 meters drilled in oil drilling, and global annual demand continues to grow. Liming Heavy Industry has been deeply involved in the powder processing field for nearly 40 years, providing you with full particle size processing solutions from coarse powder (0-3mm) to micro powder (3μm).

Equipped with high-efficiency dust collection and noise reduction systems, it has excellent environmental performance and meets the stringent requirements of high-end fine chemical and electronic material industries.
Barite has become an indispensable key mineral resource in the industrial field due to its unique physical and chemical characteristics
Density 4.3～4.7g/cm³, 1.5-2 times that of ordinary rock. This characteristic makes it the preferred material for drilling mud weighting agents.
Insoluble in water and acids, extremely stable chemical properties, high temperature and corrosion resistant, maintaining original performance even in harsh environments.
Mohs hardness 3～3.5, easy to crush and grind, suitable for efficient powder processing using Raymond mill, vertical mill, and other equipment.
Barite contains no harmful elements, is non-toxic and non-radioactive, and can be used in food-grade and pharmaceutical-grade applications, meeting environmental safety standards.
Has excellent absorption capacity for X-rays and γ-rays, widely used in medical contrast agents and nuclear industry protection materials.
Pure barite has high whiteness and large refractive index (1.63-1.64), making it an ideal raw material for producing high-quality white pigments such as zinc barium white.
Barite powder plays a pivotal role in several key industries including petroleum, chemical, building materials, and pharmaceuticals
Oil drilling is the largest consumer of barite, accounting for more than 80% of global barite consumption. During oil and gas well drilling, barite powder is added to drilling mud as a weighting agent to effectively balance underground oil and gas pressure and prevent blowout accidents.
Statistics show that approximately 1 ton of barite powder is consumed for every 30 meters drilled, generally requiring a fineness of 200-325 mesh (75-44μm) and BaSO₄ content ≥90%.
Barite is an important raw material for manufacturing various barium compounds. Using barite as raw material, various barium salt products such as barium carbonate, barium chloride, barium sulfate, and barium hydroxide can be produced, widely used in electronics, glass, ceramics, metallurgy, and other industries.
Barite powder is widely used in the building materials industry as concrete aggregate, radiation-proof cement, road building materials, etc. Due to its high-density characteristics, barite concrete is extensively used in radiation protection projects for nuclear power plants and hospital X-ray rooms.
Medical barium sulfate (barium meal) is the most commonly used contrast agent in gastrointestinal X-ray examinations. After ultrafine grinding and high-purity treatment, barite is made into barium sulfate suspension, which can clearly display the outline of the digestive tract under X-ray, helping doctors make accurate diagnoses.
Precipitated barium sulfate, as a high-grade filler in the paint and coating industry, has advantages such as fine particle size, high whiteness, good dispersibility, and acid-base resistance. It can significantly improve the hiding power, weather resistance, and scrub resistance of coatings.
